Grow hemp in an older greenhouse and you’ll be warned to avoid making a mistake by looking at the potential issues that can arise. Even though you have recently purchased hemp raw materials, it is possible that your greenhouse has been with you for several years and these resources are still in use.

Today’s talk is interesting because you’ll learn how hemp affects the earth, what to watch for when cultivating hemp, and how it affects the soil. To learn more, continue reading.

Growing In Older Greenhouses

Greenhouse farming has numerous advantages, including extending the plant’s growing season, increasing crop variety and decreasing pests and other risks from the outside environment.

The Problems Of Growing Hemp In An Older Greenhouse - Krostrade

However, in certain cases, you have greenhouses that have been in your possession for a long time. Quality and capability might decline just like many other things. Hemp requires a lot of soil and other resources, which means it will always be available.

Considerations include:

  • Planting all year round
  • Production of seeds and seed improvement
  • Lengthened harvesting times
  • Produce that has been fine-tuned
  • Termite and pest control
  • Regulations in your area have increased.
  • There are a limited number of resources available.

Once you’ve got these hemp plants in old greenhouses, you won’t have any issues.

How Does Hemp Affect The Environment?

You need to rethink the relationship between hemp and sustainability. Hemp has a wide range of applications that contribute to its long-term viability. Hemp-based products, for example, may be recycled and reused, and they are 100 percent biodegradable when properly disposed of. It has been proposed that hemp can help reduce climate change because of the way it processes ecological materials.

Hemp can be environmentally sustainable for a number of reasons. Hemp is resistant to pests and diseases since the use of these compounds, as well as fungicides, contributes to the improvement of biodiversity. Soybeans and cotton don’t need pesticides to thrive, but hemp, especially in highly commercial environments, must.

Then, hemp saves water as well. Hemp, on the other hand, is a crop that does not necessitate the use of water. Older greenhouses, on the other hand, may limit the flow of water and so interfere with the irrigation system needed to grow hemp. As a result, in order to grow hemp, a fresh greenhouse is required.

Deforestation has been slowed by hemp, according to some reports. Hemp reduces deforestation because it is recyclable, which reduces the amount of land lost to deforestation on a global scale.

What Are The Features That Hemp Growers Should Consider?

Well-Built Structure

You need a sturdy and up-to-date structure in place. It is possible that the greenhouse is too old to support the production of hemp, therefore addressing the question of what are the difficulties of growing hemp in an older greenhouse.

When building a greenhouse, it is imperative that it be capable of withstanding the most extreme weather and climate shifts.


There are greenhouses with advanced features like an environmental-controller that aren’t all the same. Do the crops benefit from it?

Growers may keep an eye on their plants without having to keep an eye on the growth area of the greenhouse at all times.

Accurate Heating And Cooling Systems

The greenhouse acts as a self-contained heating and cooling system. Farmers and gardeners alike need to be aware that temperature has a substantial impact on crop health. It has to be precisely right for this to work. Crops can’t develop to their full potential in either extreme cold or heat.

Efficient Lighting

If you’re driving by a greenhouse, you may be surprised by the lighting. Lighting plays a major role in ensuring that the fruits and vegetables get the amount of light they need without increasing the overall cost. The process of photosynthesis is dependent on sunlight, and without it, it may be affected.

What Does Hemp Do For The Soil?

In a greenhouse ecosystem, hemp and soil operate in harmony. For a variety of reasons, hemp plays an important role in crop rotation. In addition, even if it is an annual crop, the roots will penetrate deep into the soil, helping to stabilize the soil and reduce erosion.

A more delicate sort of growth is possible when this occurs.

Is Hemp Really Better Than Cotton?

If you’re growing hemp because you want to be able to use it medicinally, your options are somewhat limited. However, if you’re growing hemp just for the fun of it, addressing the question, “Is hemp better than cotton?” is a good place to start.

Hemp, without a doubt, is better for the environment than other agricultural crops. For example, hemp-based fabrics are more trustworthy, more durable, and better insulated than cotton-based textiles, for example. In comparison to hemp, the fabric might be softer and more comfortable to wear on the skin. In addition, the fiber may have a rough texture, which could help protect it from fraying.

There are a few things to keep in mind while trying to cultivate hemp in an older greenhouse if you don’t want to run into too many troubles. You should be able to take your greenhouse farming to a whole new level if you keep these things in mind.

Advantages of growing hemp in a greenhouse

Hemp was removed off the list of Schedule I Controlled Substances by the passing of the 2018 Farm Bill, which was signed into law last year. In 1937, the Marihuana Tax Act rendered hemp illegal because of its resemblance to marijuana. Hemp has been produced for hundreds of years all over the world for its versatility as a textile and for its health advantages. Hemp can now be classed as an agricultural commodity under the 2018 Farm Bill.

Agricultural, construction, automotive, furniture, paper, recycling, textiles, personal care, and food and beverage industries are just a few of the many sectors that hemp may be employed in, according to industry experts. CBD oil extraction and the cultivation of hemp seeds for consumption have become increasingly popular in recent years.

Many people interested in generating CBD or health goods are now cultivating hemp in greenhouses rather than on the open fields where it has historically been cultivated for bulk production of fibers and other industrial items.

Grow your hemp all year

Hemp can only be harvested once a year, even in places with mild temperatures for the majority of the year. When planted in a greenhouse, hemp can be harvested all year round and several times, as it is much easier to control the climate in a greenhouse. Your hemp plants can be moved into vegetative development in the winter and into blooming in the spring or summer, depending on your environmental conditions and the natural sunlight that is allowed in through a greenhouse. In a greenhouse, you may potentially improve your annual CBD production by trimming plants earlier in the vegetative cycle.

Fewer pest problems

Even if you’re growing hemp for CBD production in an indoor greenhouse, pest management is a key concern. However, pest management is much easier in a greenhouse environment. Pests, rats, and even birds can all find their way into the fields where hemp is grown. Many pesticides must be used, which can be pricey and unhealthy for the environment or final product, as a result of this. We can better manage pests in a greenhouse environment since biocontrols are limited and only work where they benefit the crop. Pests that could harm your crops will be kept out of the greenhouse. Using a greenhouse to grow your food means fewer pesticides are needed, and you have more control over what goes in and comes out of the greenhouse. To reduce mold and mildew growth caused by high humidity, make sure you have climate control in place.

If you’ve opted to grow hemp in a greenhouse, there are a few things to keep in mind:

Consider your location

Before making any further decisions, you need to decide where to cultivate your hemp and where to locate your greenhouses. Your available area is an important consideration if you’re starting small and hoping to add more greenhouses along the road. You should also try to locate your building such that it receives as much natural light as possible. This will help you save money on electricity and cut down on the amount of extra lighting you require.

Choose your structure

For your hemp production operation, it is important to choose the most practical and cost-effective greenhouse construction that can be quickly expanded upon if necessary.

Hemp and marijuana grow well in poly-connected greenhouses because they are so adaptable. For large-scale producers, a greenhouse that can be expanded upon is the most cost-effective alternative. In addition to the gutter vents, natural ventilation options like the gothic arch provide excellent condensation control and the most effective and efficient circulation.

Hemp and marijuana can be grown year-round in a Cold Frame greenhouse or a hoop house. With the addition of fans or natural ventilation, hoop houses may be transformed into an excellent beginner greenhouse for any sort of grower.

You will need to consider blackout curtains

The flowering stage of your hemp plants will necessitate periods of pure darkness. During the flowering stage of plants like poinsettias, mums, kalanchoes, or marijuana, blackout or light deprivation curtains are employed to ensure that no light may enter the greenhouse. To force your hemp to flower, you’ll need to provide it with 12 hours of darkness every day. On greenhouse gutters, blackout curtains can be readily fitted from truss to truss. Make sure that your greenhouse’s side walls, doorways, and exhaust fans are all covered to prevent light from leaking in. Light deprivation curtains and various curtain systems can be found here.

We’ve barely scratched the surface when it comes to hemp’s health advantages. We should expect to see more hemp grown in greenhouses in the future as demand for low THC, high CBD health products grows.

If you’re thinking of growing hemp in a greenhouse, give the pros at GGS a call. They can help you get your idea off the ground.

Should You Grow Hemp in a Greenhouse?

Some hemp crops are more suited to growing inside, while others aren’t. Growers of CBD hemp, on the other hand, may have more success in climate-controlled greenhouses. Fiber hemp crops, on the other hand, thrive better in the open air, where they may stretch toward the sun without having to put in as much effort into flower development.

Although cultivating hemp in a greenhouse can increase yields, it also comes at a price. Moreover, It is vital for farmers to invest in greenhouse renovations in addition to other hemp farming equipment in order to properly cultivate CBD hemp. The upkeep and electrical costs are also increased by these modifications. Those with low start-up funding may want to put off purchasing a hemp-friendly greenhouse setup until they have more money and expertise cultivating hemp.

Benefits of Growing Hemp in a Greenhouse

Hemp can be grown in a greenhouse for a variety of reasons. The first benefit of extending the growing season is an increase in yield. Even if light deprivation curtains and other greenhouse adjustments are needed to lengthen the growth season, growers can continue to grow and harvest CBD hemp all year long. This gives them a leg up on the hemp biomass buyers and brokers in their area, which is a huge advantage. There are less competitors in an untapped market, therefore it’s easier to sell your goods.

Additionally, cultivating hemp in a greenhouse offers protection from pests and invaders, which is another benefit. Although a greenhouse is unlikely to guarantee a pest-free environment, cleaning techniques can help minimize infestations dramatically. Deer and rabbits, as well as those who may mistake hemp for marijuana, can be protected by greenhouses.

Modifications Necessary for Growing Hemp in a Greenhouse

In comparison to growing hemp outdoors, growing hemp inside requires a lot more planning and effort. To maintain vegetative growth or to stimulate flowering at the appropriate moment, CBD hemp requires specific illumination conditions.

Its photoperiodic features are ideal for individuals who desire to manage the size and harvesting of plants. A precise timetable is required for light and dark times. Crop stress can occur if a precise lighting schedule is not followed. Stress on hemp plants can increase THC levels, reduce seed output, and degrade the quality of the finished product.

Hemp Lighting Schedules

Although magnificent CBD hemp flowers can be produced using a natural outdoor light schedule, additional greenhouse modifications are required to lengthen the growing season. Timed blackout curtains and additional illumination are two of the most popular greenhouse modifications used to cultivate hemp. Using increased lighting, farmers can, for example, start seedlings earlier by guaranteeing that they have more than 14 hours of light every day. Premature flowering of seedlings may occur if sufficient lighting is not provided, resulting in a significant reduction in final yield.

To make the most of hemp’s longer growing season, consider using supplemental illumination. As a result, the eventual harvest weight is increased because the plants can grow larger before they begin producing flowers. This strategy, however, necessitates the use of blackout curtains in order to properly timing flowering. In addition, a specific timetable must be followed when using blackout curtains.

The precise lighting cycle of hemp necessitates automated devices, even if growers can employ blackout curtains manually. These systems reduce the likelihood of human mistake by using timers to regulate lighting and curtains on a set timetable.

5 Features Every Hemp Grower Needs in a Greenhouse

As of late, hemp has been making waves in the agricultural community around the country. If you haven’t already, it’s worth your time to learn more about this fast-rising crop.

Hemp, the non-psychoactive relative of cannabis, has long been recognized as an economical source of fiber, seeds, and natural oil, but demand for hemp-derived products, such as CBD, hemp oil, hemp textiles, and many more, has recently surged.

Since the passing of the 2018 Farm Bill, there has been a surge in the number of American farmers interested in cultivating hemp as part of their crop rotations. Many growers utilize a hemp propagation greenhouse to develop huge, reliable, and efficient hemp crops, but the process isn’t as simple as sprinkling seeds and waiting for spring.

When it comes to growing hemp, a well-equipped greenhouse can be a tremendous assistance. If you’re planning on establishing a hemp greenhouse, we’ve compiled a list of the five most crucial considerations to keep in mind when doing so.

1. A Reliable, Well-Built Structure that Meets All Building Codes for Snow and Wind Loads

Even if you apply the best growing methods and advice available, your crops will be vulnerable to the elements if the greenhouse construction itself cannot protect them.

As a result, it’s vital that the greenhouse you construct for your hemp plants is capable of withstanding the worst of Mother Nature’s fury.

Well-built greenhouses are capable of withstanding high snow loads and high winds up to blizzard levels without crumbling. When it comes to securing compliance with local construction codes, in most circumstances, this will be required to meet basic strength standards.

Our Rimol Hemp propagation greenhouses are meant to be as easy to secure a building permit for as feasible and are specifically designed with high snow and wind load protection in mind.

As an example, our Highpoint Nor’easter hemp greenhouse offers 2-foot bow spacing to meet typical snow and wind loads, with the possibility to add more structural components for higher load requirements. (See image below) Assemblies at each set of bows add to the highpoint’s strength, while a 6:12 roof pitch composed of high-strength galvanized steel tube prevents snow from piling up.

To ensure that our greenhouses are some of the strongest and most protected for today’s hemp growers, these design components work together to deliver stamped engineering blueprints with each greenhouse so you can receive your building permit without encountering any unforeseen issues.

2. A Top-Notch Environmental Controller

There is no doubt in our minds that cultivating hemp is a labor of love… Most hemp growers, on the other hand, can’t devote the time necessary to constantly monitor their greenhouses and make quick adjustments when necessary.

Using a good environmental controller, producers can keep a careful eye on their plants (and make quick environmental modifications) without having to personally monitor the growing area all day long.

When it comes to hemp cultivation, this is especially true, as the desired yield often necessitates very specific climatic conditions. One of our hemp propagation greenhouse solutions is the Link4 iGrow 800. This environmental controller allows you to automate every part of your greenhouse, from lighting to temperature and humidity.

A single pre-mounted, pre-wired, and pre-tested control panel can monitor all of your greenhouse’s environmental systems (or several greenhouses) with the iGrow 800. This enables producers to remotely monitor and quickly modify the conditions in all growing spaces from any computer or mobile phone talking with the environmental controller.

For growers that want to save time and money when switching from antiquated control systems, a UL-approved, pre-wired environmental controller is a great option.

3. Precise Heating & Cooling Systems

As any farmer knows, temperature has a significant impact on the health of your harvests: if it’s too cold, your plants may lack the energy to reach their full potential; if it’s too warm, your plants may suffer from heat stress or be more vulnerable to pests and diseases.

Temperature and humidity can be difficult to maintain, even in a greenhouse, which is why precise heating and cooling systems are so vital.

Our hemp greenhouses are designed with excellent heating, cooling, and ventilation systems to meet this need precisely for this reason. Controlling the temperature and humidity levels in each hemp greenhouse is made easier by these systems when connected with an environmental controller.

In the case of our Highpoint Matterhorn hemp greenhouse, for example, the cooling and ventilation systems are designed to meet the precise needs of your greenhouse, using high-efficiency, OSHA-compliant fans built to last long and provide three phases of ventilation for precise cooling throughout the growing season. Evaporative cooling can also be used by growers in the hottest months of the year.

Similarly, our hemp greenhouses are equipped with high-quality Reznor heaters, which include all the required technology and controls to ensure that your greenhouse grows at its maximum temperature. Direct spark ignition is used on all heaters in this high-efficiency power vented heater, making it suited for growers in all Plant Hardiness Zones.

Propagation of hemp is a complex and critical process that involves heating and cooling. From the beginning, producers may avoid many of the most common errors and problems faced by many first-time greenhouse hemp growers.

4. A Fully-Automated Light Deprivation System

As every seasoned hemp or cannabis grower knows, light deprivation is a significant factor in the development process. Even if you’re cultivating hemp specifically for the extraction of CBD, an automated light deprivation system is a must-have to provide complete control over your final product’s quality.

It’s possible that precise periods of light deprivation are required to help hemp cultivars reach their target plant size, terpene profile, or CBD concentration based on the photoperiods of their individual cultivars. So, instead of relying on the sun and seasons, many hemp propagation greenhouses use light-proof coatings during specified time periods in order to simulate and maximize these photoperiods.

Human light deprivation systems, on the other hand, necessitate a lot of manual labor and can be prone to light leaks and other inefficiencies, all of which can reduce the effectiveness of your system and harm your hemp plants. Because of this, growers that want to get the most bang for their buck typically turn to automated light deprivation systems.

Fully automated, motorized light deprivation systems are built right into our hemp and cannabis production greenhouses, and they have superior perimeter sealing to fit snugly and reduce light leaks. These automated systems, which are composed of high-quality, flame retardant fabric and have a slope-flat-slope pattern, are highly reliable and effective in blocking light during blackout times. An automated controller with a manual override feature makes it straightforward to regulate these photoperiods.

Farmers who still use manual light deprivation systems to control photoperiods may be expending more time, effort, and resources than they need to, and their systems may still be prone to light leaks and inefficient performance, as well. Hemp plants require precise light levels for optimum productivity, which can be provided by an automated light deprivation system.

5. Energy-Efficient Grow Lights

For as vital as it may be to keep your hemp plants from getting too much light during specific photoperiods, it may also be necessary to add supplemental lighting to your greenhouse during the short winter months to ensure they get enough light.

Adding additional lighting to your hemp greenhouses, however, can result in a large increase in energy consumption, which can result in additional costs for the same crop. In order to make sure your plants are getting the light they need without racking up unnecessary costs, we urge hemp growers to use reliable, energy-efficient grow lights for hemp farming.

Using high-quality, high-efficiency grow lights, Rimol can outfit your hemp greenhouse to suit your lighting demands while keeping energy expenses in check. It is possible to manage photoperiods using these lights, especially when they are used in conjunction with an automated light deprivation system.

Is Greenhouse Hemp Growing for You?

New methods of growing food in a controlled environment (CEA) have revolutionized agriculture. When it comes to growing hemp, it’s only natural that greenhouse technology from the CEA is influencing certain farmers. The usage of greenhouses for the cultivation and manufacture of premium hemp products is becoming more popular among growers who prefer to cultivate their crops in a more controlled environment.

But, are you interested in growing in a greenhouse? Growers of hemp in greenhouses were interviewed by Hemp Grower to learn more about the advantages and disadvantages of this type of farming. For these reasons, greenhouse farming has become more popular.

1. Year-Round Cultivation

Hemp harvests are no longer limited by the seasons thanks to greenhouse technology. Denver-based hemp firm Ambary Gardens grows cannabidiol (CBD)-rich hemp in greenhouses that may be used all year round. Cultivation experts Nick Stay and Josh Howdyshell use light deprivation and additional LED lighting in their 8,000-square-foot plant to assure eternal harvests.

Outdoors, “you’re kind of limited to one opportunity a year, so all your eggs are in one basket,” adds Howdyshell. In order for us to be able to flower year-round, we use light deprivation, which is impossible for an outside grower to do.” Plants are able to blossom at any time of the year if we can reduce the days.”

Hemp Solutions of Minnesota, based in the Minneapolis-St. Paul metro area, has added greenhouse production to its 50 acres of outdoor hemp, according to Paul Frank, CEO and founding partner. The company cultivates flower (primarily for the manufacturing of CBD oil) and also grows and sells clones. Autoflowering strains [that don’t depend on photoperiod] and classic strains may both be grown year-round in our northern climate if they are kept warm enough in the indoors, according to the expert.

2. Seed Production, Breeding and R&D

As well as hoop houses and 100 acres of outdoor hemp farmed for CBD, High Elevation Hemp operates a state-of-the-art greenhouse on Colorado’s Western Slope with a floor area of 9,000 square feet. Martin Muldowney, a co-owner of the enterprise, states that the greenhouse is used mostly for seed production for sale and personal consumption. Preparation for outdoor growing season and airborne pollen is done early in the year.

In order to create our own feminized seeds, we must use light deprivation, he explains. “The light deprivation greenhouse is where we undertake all of our seed production. As a result, we grow all of our crops there.”

Hemp-growing in greenhouses was a natural progression for Wheatfield Gardens, a hydroponic lettuce producer in New York. With this plan, a completely artificial light-lit grow chamber was part of it.

CEO Paal Elfstrum of Wheatfield says the indoor area is critical to seed manufacturing, clones, and new variety trials. He explains, “Hemp is a science that is still in its infancy,” and he’s right. It’s possible to regulate every aspect of the environment in that indoor space, making it ideal for research and development.

3. Extended Growing Seasons

It is likely that future improvements will include light deprivation as well as other methods of increasing the seasonality of Wheatfield’s core hemp output.

When production begins in April, the business will have fewer than half of Wheatfield’s greenhouse acres covered in glass. When it comes to cultivating hemp for CBD, “all outdoor hemp growers in New York need to have a head start on the season,” Elfstrum explains.

Elfstrum’s seasonal greenhouse program allows for several crop cycles by focusing on autoflowering hemp types, which are typically ready for harvest in 60 to 90 days. Indoor growers have an advantage over their outdoor counterparts since they have a few more weeks of spring development and fall maturation.

An early September frost can influence the entire outcome of outdoor crops in Ambary’s location, according to Howdyshell, a risk that can be alleviated with a climate-controlled greenhouse.

It is possible to create controlled environments in greenhouses that are impervious to weather hazards such as wind, hail, and drought. Regardless of whether the clones are going to be used in the field or in a greenhouse, they need a loving atmosphere. According to Howdyshell, it’s “certainly a vital component [for clones], especially for outdoor gardens”.

It is also possible that greenhouse buildings can assist prevent cross-pollination from adjacent fields. Pollen drift, according to Muldowney, is one of the most significant dangers to outdoor gardeners. Because pollen can still enter through vents and other open entry, High Elevation restricts indoor seed production to non-pollen seasons, even with its greenhouse. Hemp smoked by High Elevation can only be found in the company’s greenhouse.

“Outdoors, we’re only cultivating for CBD extraction. Because of the high levels of pollen, it’s becoming impossible in many locations to grow hemp that can be smoked. When it comes to a smokable product, “everything is getting seeded,” he explains. When a plant is pollinated and produces seeds, the percentage of CBD in the plant drops. As a result, you lose a significant amount of muscle mass. It is a threat to the manufacturing of CBD.”

Elfstrum expects cross-pollination issues to rise as hemp acreage designated for fiber and seed purposes grows. When it comes to cannabinoids, “outdoor farmers trying to grow [for] cannabinoids are going to really run into some risks,” he says. Within a 5-mile radius of your CBD farm, your entire crop is likely to be pollinated, resulting in a dramatic drop in cannabinoid content.” Pollen can travel a distance of 10 to 30 miles in most cases, according to Hemp Grower’s research.

Despite Muldowney’s belief that greenhouse farming offers some protection from pollen, he maintains it isn’t a panacea. Also, we [develop] seeds because of this. For the sake of alleviating some of these issues, we’re working hard to supply our area with feminized seed at a reasonable price. In order to be a good neighbor, you must aid your neighbor and help your neighbor comprehend.

5. Optimized Yields

greenhouse farmers have the advantage of overcoming environmental variables, but also have the chance to enhance nature and optimize growing conditions for hemp cultivators in greenhouses.

As a result of not being subject to the whims of the weather, we are able to maintain stable growing conditions. We have better control over soil quality, water utilization, and [pests] in a controlled environment,” Muldowney explains. “Our cannabinoid profiles are improving because the plants are seeing a better environment that is better suited to their requirements.”

An LED-supplemented greenhouse guarantees that the crop receives appropriate light levels year-round at Ambary Gardens, which produces full-spectrum CBD (including all the cannabinoids naturally found in the plant, as opposed to a CBD isolate). Trials at the facility in 2016 contrasted an Ambary hemp strain produced with full-spectrum LEDs to an Ambary hemp strain grown with natural light in 2016. The yield of useful plant material increased by more than 40% as a result of the LEDs, and yields per plant were more consistent as well. Despite the higher costs of lighting and energy use, Howdyshell and Stay claim that the improvements in yields, potency, and efficiency more than made up for those costs.

Howdyshell explains that “by growing indoors, we are simply reducing any unnecessary plant stress.”

Microgrids at Wheatfield Gardens use carbon dioxide as a byproduct of generating electricity and heat (CO2). The greenhouse is then filled with CO2 as a result of this process. The CO2 in the air of a greenhouse or grow room can be depleted swiftly by actively growing plants, according to an article in Hemp Grower’s sister journal Cannabis Business Times. When the concentration drops below 200 parts per million (ppm), plant growth halts…. Cannabis harvests can be increased by 10% to 25% if levels of 800 to 1,000 ppm are used,” according to research.

Elfstrum believes that “hemp responds quite effectively to CO2.” “A much larger plant will be built for us.”

6. Pest Pressure and Control

It’s not possible to completely eradicate pest and disease issues when growing hemp in a controlled greenhouse setting, but it does shift the focus and allow for new methods of controlling them. In the case of pesticide-free hemp farmed using organic agricultural methods, this is extremely significant.

Outdoors, there is a lot of rivalry between good and bad bugs, resulting in a natural equilibrium. ” It’s quiet in the greenhouse because we’ve made it so that these plants may grow in peace.” As a result, “if we’re not vigilant, pests can easily take over if we aren’t careful.” Predatory mites and wasps are only two examples of Ambary’s multi-faceted approach to pest management.

High heat and humidity are perfect breeding grounds for pests and plant disease in confined greenhouses if environmental controls aren’t in place. It’s not all rainbows and sunshine in the greenhouse,” says Elfstrum, who stresses the importance of humidity control in preventing disease. It’s crucial to have good air circulation in the room…. An active approach is needed to prevent the development of a mold farm.”

7. Increased Regulation Ahead

According to Elfstrum, supply chain traceability is a given in the CBD business because of the increased control provided by a greenhouse growing environment.

Lettuce has taught us a thing or two about food safety and standards… “We need to be able to track a problem back to the seed if it affects a head,” he explains. “We understand the significance of this, especially for large merchants that are risking the reputation of their brand… Brands that don’t know where their raw materials come from tend not to sell them in mainstream retail outlets.”

8. Limited Space or Resources

Field production may make more sense for producers whose primary goal is fiber production, according to Howdyshell and Stay’s analysis. For fiber production, you need a lot of land and a lot of plant material. There is just not enough room in a greenhouse for a textile-based crop, therefore it makes sense to grow it outside, explains Howdyshell. In order to justify the energy costs and other such expenses while growing indoors, cultivating for resin—not just CBD but also terpene content and other cannabinoids—helps with the financial return. In that greenhouse setting, we can really make the most of that.”

Muldowney advises hemp producers who are thinking about growing their crop in a greenhouse to first learn about and understand the needs of their target market. Because of the higher price of hemp smokable, he explains, selling indoors makes sense. “If you are just growing for biomass, I would never suggest growing in a greenhouse because your costs are just too high. You must be aware of your expenses and confident in your ability to recoup them through the sale of your product.

Concluding Growing Hemp in a Greenhouse

According to Muldowney, knowing and understanding your market’s needs is essential for any hemp producers considering greenhouse production. Because of the higher price of hemp smokable, he believes that selling indoors makes sense. As a biomass grower, I would never recommend a greenhouse since the costs are simply too high.” If you can’t sell it at a price that works for you, you need to know your costs.
