Understanding the nature of cannabis and the benefits it can provide is essential to successful greenhouse cultivation. Is it a good idea to add cannabis to your garden? The best gardening advice and tips can be found here.

What Is Cannabis?

This controversial item is a term for a family of plants including Cannabis sativa, Cannabis indica, and Cannabis ruderalis, all of which have psychoactive properties.

Drugs, commonly known as marijuana, are produced by harvesting and drying the plant’s flowers. With each new state that legalizes marijuana, the vernacular for these plants evolves to reflect the new norm. Common parlance now refers to cannabis as the weed.

There are those who insist a more appropriate name be found for it. There are those who think it should be neutral, especially when compared to words like “pot” and “weed,” which many people associate with negative connotations of illegality. The topic of race is also brought up in some of the comments.

What Are The Health Benefits Of Cannabis?

Many people have reservations about using cannabis or marijuana because of the addictive properties that have been linked to it. However, it will yield a number of positive outcomes when put to use in the realm of health.

Aids in weight loss

The use of cannabis has been linked to reduced body fat. People who use cannabis tend to maintain a healthy weight, which can be attributed to the drug’s role in insulin regulation and the body’s ability to burn fat more efficiently.

Improves respiratory system

Growing cannabis means you have access to herbs that help your lungs breathe better. In contrast to tobacco smoke, which can irritate lung tissue, cannabinoids in cannabis may actually have the opposite effect and enhance breathing. It doesn’t do any harm and actually aids in enhancing the lungs’ capacity to function.

Fights cancer

Cancer prevention is one of cannabis’s most notable health benefits. Cannabinoids have been linked to a reduced risk of developing cancer, and there is evidence to suggest they may help combat the disease.

Regulates diabetes

Regulating glucose levels in diabetics is another area where cannabis has been shown to be helpful. Cannabis’s known effects on insulin explain why it can control blood sugar and ward off diabetes. Cannabinoids in cannabis have been shown to improve blood circulation, blood sugar control, and blood pressure regulation.

Helps to treat seizures

CBD, also known as cannabidiol, shows promising results in the treatment of epilepsy. Studies on the effects of cannabis on people who have been diagnosed with epilepsy are ongoing.

Promotes treatment for glaucoma

Patients with glaucoma may experience discomfort due to the increased pressure on their eyeballs. As a short-term solution, it can help alleviate symptoms by lowering intraocular pressure.

Provides relief for sclerosis

Cannabis has been found to be helpful for the pain associated with multiple sclerosis. Muscle spasms associated with MS can be excruciating, but cannabis can ease the discomfort.

How Do You Grow Cannabis In A Greenhouse?

Is greenhouse cannabis cultivation subject to any regulations? Absolutely. In recent years, the trend of “grow your own” cannabis has swept the gardening world by storm. Many people find that it is easier to cultivate these seeds in the greenhouse than in a specially constructed indoor space.

The process is simpler for these farmers than tending to cannabis plants in open fields. Greenhouses are widely regarded as the most effective means of defending plants from the weather, grazing animals, and predatory insects.

Further, indoor gardens provide an extended growing season, allowing you to harvest your cannabis earlier than you could outdoors. Harvesting these plants in the greenhouse gives you a better chance of success despite the harsh autumn weather. Growers in many parts of the world are now able to cultivate high-quality cannabis seeds thanks to the many benefits of greenhouse cultivation.

There are things to think about when cultivating cannabis.

Greenhouse capacity

If you are currently planting or constructing the facility with the eventual intention of relocating to the greenhouse, you should plan ahead so that the greenhouse can be supplied with a high volume of vegetation for plants no taller than 24 inches.

Greenhouse plants are a necessity when planning an indoor facility for the cultivation of mother plants, clones, or vegetative crops. By doing so, you can protect the young plants from unnecessary stress while still getting the most out of your efforts. When plants enter their flowering phase, they are susceptible to disease for about 10 weeks.


When designing your greenhouse, one of the most crucial factors to consider is the material used for the roof. Different types of greenhouse covering with varying ultraviolet inhibitor percentages are available from different manufacturers.

To slow down the breakdown of the coverings and whatever they protect, these inhibitors are essential. They also aid in regulating heat loss and gain, as well as leaf and canopy temperatures, both of which can be detrimental to plant health when temperatures rise above 75 degrees Fahrenheit, the point at which photosynthesis is effectively halted.

Heating procedures and cooling processes

Greenhouses are known to provide cultivators with the right advantages if planned and managed correctly. Before making the switch to greenhouses, it’s important to learn all you can about the variables that affect greenhouse yields.

Ideal Temperature Control for your Cannabis

It’s worth pausing to consider that the ancestry of cannabis can be traced back to Central Asia and the Indian subcontinent. It’s warm and dry there for most of the year, with mild temperatures overall.

Cannabis first adapted to these types of growing conditions, and despite centuries of cultivation in other climates, the plant still prefers sunny, dry areas.

Temperatures in the cannabis greenhouse should hover around the ideal range of 70 to 80 degrees Fahrenheit (not too hot, but warm enough to keep your plants happy). Assuming you have a greenhouse, the sun’s heat (through the covering) and the plants’ own heat (through the greenhouse effect) should be sufficient to keep your plants warm during cold weather.

If you live in a particularly frigid climate, investing in a high-quality greenhouse heating system that allows you to precisely regulate the greenhouse’s interior and increase the heat as needed may be essential for your cannabis garden. Similarly, during the warmer months, it can be especially important to have adequate cooling and ventilation to avoid a buildup of heat. Your plants will be grateful if you take the time to consider their needs in light of the climate where you live when designing your grow space.

Humidity Controls in an Artificial Indoor Grow Room

There is no guarantee of a favorable temperature range for those who choose to cultivate cannabis outside of a greenhouse, but many plants do manage to flourish and survive in the open air. However, humidity is arguably just as important, if not more so, than temperature when it comes to producing the best cannabis possible.

To prevent your cannabis plants from drying out in the heat, it’s important to maintain an appropriate humidity level. This may also be your best defense against crop-destroying mold. Tending cannabis is a delicate balancing act; the plant’s dense flowers can quickly become diseased if they are exposed to too much moisture. One of the keys to protecting your plants through the changing seasons is maintaining an environment with just the right amount of dryness and humidity.

Typically, seedlings and young plants respond best to slightly more humid conditions, between 60 and 70 percent. By the time your plants have fully flowered (around week 9), it is best to turn the humidity down a little and aim for around 40 percent.

Automatic environmental controls can measure moisture levels and vent or dehumidify as needed, making them a good option for cannabis greenhouses where humidity control is a priority. Setting the optimal humidity level and letting the greenhouse take care of the rest is quick, easy, and beneficial to crop yields.

Safety For Your Cannabis Crop

Your greenhouse is now set up to provide optimal growing conditions, your plants are adequately spaced, and you are on top of your growing and trimming schedule. Your cannabis crop is doing wonderfully, until one day you go out to check on it and find that it has been robbed.

It would be irresponsible to ignore the need for security when dealing with a cannabis grow, as cannabis remains a highly valuable crop. Due to the urgency of the situation, many farmers have been forced to move their operations underground, forgoing the healthful effects of natural light and air in favor of the relative safety of enclosed spaces. You won’t have to make any of those sacrifices when you have a safe cannabis greenhouse.

Blackout of end walls and blackout curtains including light traps can improve light efficiency and are examples of basic camouflage used in secure cannabis greenhouses. More advanced security features include higher side walls, lockable doors, and other accessories to secure the roof and walls.

How long does it take to grow cannabis?

Wylie estimated that a plant would be ready to be picked after 50 to 60 days. The plant must then be dried for a period of 10-14 days after harvesting. After that, he said, growers can either smoke their weed or let the flowers cure for another week or two to improve the quality.

Where can I buy cannabis seeds?

Phoenix Seeds & Clones is a local retailer that sells grow consultations for $75-$200, which comes with 5-20 seeds. Gorilla Cake, Tangie Cookies, and the high CBD Kino Vision strains are just a few of the options available.

Phoenix Seeds & Clones has run out of seeds as of October 19; however, interested customers can sign up for an email list at phoenixseedsandclones.com to be notified as soon as new stock arrives.

Leafly and similar sites also sell cannabis seeds to the general public. As Sundberg cautioned, good seeds can be costly. Only female plants produce flowers, so purchasing seeds is also a risk because you never know how many male and how many female seeds you will get. Feminized seeds are more expensive because they have been modified genetically to produce only female plants.

When shopping, only deal with reputable vendors to avoid getting ripped off. Sundberg suggested the California-based businesses Canna Genetics Bank, which sells seeds from a variety of breeders, and Neptune Seed Bank.

He cautioned that people “have a few rounds that are really disappointing” before they find the best phenotype when growing from seed.

As reported by the Arizona Republic, The Plant Stand of Arizona co-owner Eddie Smith has confirmed that in the near future, seeds for cannabis will be sold from the nursery’s location in south Phoenix.

Dig It Gardens co-owner Ryan Jerrell said the Phoenix-based nursery will sell cannabis seeds and “starter kits” to novice cultivators in the near future.

Where can I buy a cannabis clone?

Clones can also be purchased from Phoenix Seeds & Clones.

Clone refers to a cutting taken from a living cannabis plant that can develop into a new plant. The new plant is a clone because it shares the same genetic material as the parent plant.

Wylie thinks cuttings are better for beginners than seeds, but due to the novelty of Proposition 207, he is unaware of any legitimate businesses selling cuttings in Arizona at this time.

He suggested planting several seeds at once, labeling each plant, and taking a cutting from each one before they flower if one wanted to clone their own plants. The most fruitful plant can have a cutting grown from it.

What’s the easiest cannabis strain to grow for beginners?

Wylie advised inexperienced growers to start with a hybrid strain, and to avoid strains with the word “OG” in the name or those labeled “exotic,” as these can be difficult to cultivate. He gave the example of the popular 50/50 hybrid Blue Dream as a plant that can withstand both hotter and cooler conditions.

Green Crack, Grape Diamonds, and Cherry Garcia were some of the other hybrids he recommended for novices.

What else do I need to grow a cannabis plant?

The three most important requirements for successful cannabis cultivation, according to both Wylie and Sundberg, are nutrient-rich soil, water, and light.

Dig It Gardens and The Plant Stand both stock FoxFarm soils, a well-liked brand among cannabis farmers. According to Sundberg, the best place to get his favorite blend of Nectar of the Gods, Blend #4, is at PHX Hydro in west Phoenix.

Wylie emphasized that incandescent bulbs are inadequate for indoor cannabis cultivation because the plant requires full spectrum light. He suggested getting a cheap grow light as a first step. In Tempe, you can buy grow lights from Sea of Green Hydrogardens.

As a voice of caution, let me say… You have to learn to crawl before you can learn to walk,” Wylie advised. “Discover how to see your plant through from seed to harvest, then dry and cure it. Next, you can expand upon that foundation. Don’t go out and drop a ton of cash on fancy gadgets.

Living soil, which contains active microorganisms, was called a “game changer” by Sundberg. Arizona Worm Farm is a Phoenix-based supplier of compost, mulch, and worm castings.

Where is the best place to grow my cannabis plant?

Wylie predicted that the vast majority of growers would do their work indoors, in places like closets and garages. Approximately 75 degrees is ideal, he said. He recommended installing a fan to circulate the air in a confined area. A 100-watt grow light and an oscillating desk fan are all you need to get started, he said; all you need is a closet.

Cannabis can be grown almost anywhere if one is willing to make adjustments to their growing conditions, as evidenced by Sundberg’s claim that some people use “grow tents,” which resemble black boxes.

According to Sundberg, cannabis can be grown outdoors in Arizona; the plants bloom in the shorter autumn days of August and can be harvested in the following month. He assured me that it was possible to grow in Phoenix, despite the high temperatures, but that special care must be taken to safeguard the plant.

As a means of maintaining a comfortable soil temperature, he suggested mulching. He recommended using a pot that was at least five gallons in size in order to effectively create a buffer zone around the contents. The pot can be protected from the sun’s rays in a number of ways, including by placing it inside another pot or erecting an insulating barrier around it.

Spraying your plants in the middle of a hot, sunny day is tempting, but the water droplets on the leaves can act as tiny magnifying glasses, causing the plants to roast. As is the case with most plant species, a morning watering is ideal for succulents. If you must water in the middle of the day, he said to do so by discharging the hot water from your hose first and then watering the soil around the plant rather than the leaves.

How much light does my plant need?

Once cannabis seeds are planted, the plant requires a light/dark cycle of approximately 18:6 to grow in its non-flowering vegetative stage. Sundberg suggests beginners start small, so how long the plant stays in this stage is up to the grower’s discretion based on available space.

Following a few days of growth, flowering can be triggered by shifting the lighting cycle to one that consists of 12 hours of light followed by 12 hours of darkness each day. For plants to thrive during the dark period, Sundberg recommends no more than the light of a full moon.

How often should I water my plant?

Wylie advised that plants be watered only when the soil was dry. To check this, growers should insert a finger into the soil about halfway between the plant and the edge of the pot. In the event that the soil is hot and dry, watering is required.

If the water isn’t good, the flowers won’t be either. Sundberg recommends filling a jug with distilled or purified water from one of the many water dispensers around town rather than using tap water for your plants.
