What To Know When Growing In A Greenhouse: 5 Factors To Consider
Seasons and planting zones
Generally speaking, you can work in the greenhouse all year long. In the spring, you can begin sowing the seeds, while some flowers and other plants thrive better in the summer. Another advantage of planting in the fall is that you can avoid the winter frost by making modifications indoors.
Different states and regions, on the other hand, will encounter a wide range of situations. When it comes to greenhouse farming, this is where you’ll benefit from studying the planting zones. In what areas may you grow crops?
USDA planting zones are assigned to each state. To discover if your crops will thrive in your area, you need to know the planting or hardiness zone. You’ll be able to choose a cultivar or variety that’s perfect for your state before planting in a greenhouse because you’ll know what temperatures and rainfall to expect in each planting zone.
Temperature, humidity, and ventilation control
You may now modify the greenhouse’s temperature and humidity in accordance with your expected conditions and the tolerance of your plants and produce. Using the range and checking in the greenhouse on a regular basis will ensure that your plants, harvest, vegetables, and flowers are flourishing at their optimal temperatures.
A thermometer is all that is needed to ensure that you are getting accurate indoor temperature readings. A heating or cooling system can be used to alter the temperature once you have the figures in hand. Heat adjustment can lengthen your growing season, for example, if your plants are struggling in the winter.
Your plants will fare better in the summer with a cooling system. It will simply follow the current weather conditions if you don’t alter the temperature inside. When it comes to temperature management, greenhouses give you a lot of flexibility over what you can afford.
The control of humidity and failure to monitor it will cause a thirst for plants, diseases, and pests in the greenhouse. Humidity can be improved by misting while ventilation can be improved via vents or a modest fan. Changing the humidity and ventilation according to the season is also recommended.

The plants, illnesses, and pests in the greenhouse will be thirsty if the humidity is not properly controlled and monitored. Humidity can be improved by misting while ventilation can be improved by using vents or a modest fan. Change humidity and ventilation with the seasons for optimal results as well!
Watering systems
The amount of water your plants demand will determine which watering system to use and how it should be used. Overwatering or underwatering the plants can both be harmful to their health and should be avoided. Watering the roots rather than the leaves is a better strategy for preventing disease.
Pest management
As long as proper precautions are taken to minimize contamination, such as pruning, humidity control, and sanitation, pest management in the greenhouse is a breeze. However, don’t freak out if you spot pests, as this provides you enough time to deal with the problem. Read up on pests that may attack your plants so you’ll be ready if they do.
Why Grow in a Greenhouse?
As the autumnal equinox approaches, the shortened days become more and more apparent. In many parts of the country, it is too cold and dark at the winter solstice to grow much in the fields. In the meantime, greenhouse gardeners are preparing to start seedlings of tomatoes, lettuces, eggplants, and peppers. It is up to the greenhouse gardener to decide whether to start the seedlings in a heated or unheated greenhouse or hoophouse, depending on the latitude, the crop, and a slew of other factors.
Learn how greenhouse growth can fit into your business strategy if it sounds like a remedy for your midwinter blues and a chance to generate some extra money all year long…
The Greenhouse Advantage: Extended Season; Higher Quality; Higher Yield
When it’s too cold outside to plant vegetables, flowers, and herbs, you can grow them in a greenhouse instead. High pricing can be seen at some marketplaces if you’re looking to buy out-of-season veggies like tomatoes and cucumber.
Tomatoes, for example, have significant winter production costs; therefore, you should only get started if you are confident that there is a market for your product and that the price you choose will generate an adequate return on your investment. Heating and labor will be your two biggest expenses, respectively. Additional illumination may be required, especially if the weather is gloomy for an extended period of time during the coldest and shortest months of the year.
In the event that you have never attempted to grow greenhouse vegetables in the winter, it is imperative that you conduct extensive research to discover whether it is financially feasible for you. Numerous free sites can help you estimate the costs and benefits of your project. If you type “greenhouse tomato enterprise budget” into a search engine, you’ll obtain a plethora of relevant results. Regional universities and cooperative extension agencies’ publications are a good place to start looking.
The USDA’s Virtual Grower is a useful resource for estimating heating expenditures. It asks for information such as the nearest weather station, greenhouse structure type, structure condition, heating system type, and fuel price when running this free software.
Organic farmers in Vermont’s Northeastern region (NOFA-VT) provide a wealth of information about greenhouse crop production costs on their website. These tools include a cost of production worksheet, metrics summaries, and analysis tailored to specific crops.
Planting in a greenhouse in the northern United States or Canada should not begin until February 15th since the low light conditions earlier in the year make the crop more of a danger. Those that have a lot of experience and live in the southern states, on the other hand, may be able to produce all winter long. It is possible to grow a wide variety of crops, including field crops, with little or no heat by the middle of February.
Greenhouse production can be successful if you have a spring market for selling vegetables, especially when combined with early field crops. The amount of field-grown spinach you might have available in April isn’t enough to fill a market stand. Head lettuce from a heated greenhouse, arugula, radishes, and carrots from an unheated hoophouse, however, will help you put up a fine show during the event. For Mother’s Day, think about greenhouse tomatoes, cucumbers, cut flowers, and hanging baskets of flowers and ripening strawberries, in addition to a wide variety of spring veggies.
Growth in a greenhouse allows you to extend your growing season. When crops are protected from wind, rain, and hail they are more likely to produce marketable goods. Additionally, if you can provide optimal growth conditions for each crop, you can expect a larger yield. Many illnesses are kept at bay in greenhouses, including soil-borne pathogens that wash onto plants when it rains. While crops grown in greenhouses may be free of many typical field maladies. Even in greenhouses, problems like foliar disease, aphids, and whiteflies can occur, thus constant monitoring is necessary.
Tools & Supplies for the Greenhouse
Container, in-ground soil, and hydroponics are all methods of growing greenhouse vegetables, herbs, and flowers. Beginners will find it easier to get started with the first option because it requires less watering and fertilizing. There are many advantages to growing in containers, including no weeding and a lower risk of soil-borne infections. As a result, the sort of greenhouse you own could be a deciding factor. A concrete or gravel floor necessitates the use of grow bags, crates, or huge pots as containers for your transplants. You have a choice of systems if your floor is made of soil.

To save time and effort, as well as to avoid difficulties caused by overhead watering, drip irrigation is advised for both hydroponics and non-hydroponics growers. As a weed barrier, plastic mulch can also help conserve soil moisture. It is possible to keep the soil warm without increasing fuel use by using a hoops-supported inner layer of row cover.
A trellis is needed for tomatoes, cucumbers, peppers, and eggplants. In a Lower-and-Lean system, vines can be fastened to the trellis using clips, while Rollerhooks provide for maximum time and space savings. Hortonova netting, for example, can be used to support the upright growth of other greenhouse crops like basil and cut flowers. Educate yourself on the various crop support equipment and accessories available before making a decision on the system that is most appropriate for your needs.
Allows for precise planting of baby leaf greens and salad mix, which saves seed and speeds up the process significantly. In addition, a greens harvester makes short work of chopping up baby lettuce and other greens.
What to Grow in Your Greenhouse, Hoophouse, or Poly Tunnel
In a greenhouse, you can grow just about anything, but that enclosed space is great real estate — with proper variety selection, you can maximize revenues and produce foods that don’t do well outside for you.” At Johnny’s, we specialize in breeding, testing, and selecting seeds for greenhouse cultivation. Read our post on Greenhouse Trial Criteria for additional information on what we’re looking for and which greenhouse performances we suggest.
Tomatoes are the most widely grown greenhouse crop in the United States, perhaps as a result of its high and year-round demand. After lettuce and salad mix, cucumbers are the most common greenhouse crops. There is also a huge market for greenhouse peppers in the United States, which provide a wide range of alternatives while being more specialized in terms of cultural requirements. A continuous year-round demand for microgreens, as well as advantages such as a short turnaround time, relative ease in growing and a considerable ROI make microgreens a viable option.
In a greenhouse, cut flowers can be profitable as well. Among seed-grown flowers, delphinium, lisianthus, and snapdragons are the best bets for windy conditions. Heat-loving plants like celosia are ideal for greenhouse cultivation in colder climes.
While many herbs can be grown year-round in a greenhouse, basil is one of the most popular. Rosemary and thyme, two of the most delicate perennial herbs, can be preserved in the greenhouse as mother plants, then propagated in late winter to sale as container plants or culinary cut herbs in spring. Another useful greenhouse crop is strawberries, which may be grown in hanging containers in order to free up floor space for other crops.
Variety selection is critical for greenhouse success, regardless of the crops you grow. For a variety of factors, plants are deemed suitable for greenhouse cultivation. It’s possible that they’re more resistant to common infections, or that they’ll thrive in a greenhouse’s lower light circumstances. If you’re looking for a large production of cucumbers in a greenhouse, there are numerous types that are both parthenocarpic and gynoecious, which means they don’t need insect pollination to set fruit. Our website and catalogs also feature a red greenhouse icon next to the variety names.
Opening up to Year-round Possibilities
As the days become shorter and the colder months approach, you may want to consider growing some of your own food in a greenhouse or hoophouse. It’s not too early to start planning your production and making purchases and planting dates, if you decide to go ahead and do it! You can grow food in a greenhouse year-round, even if you live in a cold climate!
The Greenhouse Effect (Is a Greenhouse a Good Idea for Your Garden?)
Beautiful and practical, greenhouses are a great addition to any gardener’s arsenal. With that in mind, we’ve put together a list of pros and disadvantages to help you decide if you should build or buy one for your garden.
What is the Purpose of a Greenhouse?
Greenhouses act as a barrier between the plants you’re cultivating and the outside world, allowing you to extend your growth season and even improve it. As well as providing protection from the elements, they are also a deterrent to pests. Despite our playful usage of the phrase, the “greenhouse effect” is a serious matter for our global ecology. However, for the home gardener, a greenhouse’s positive impact on plants can be highly beneficial to plants. When it comes to a certain style of conservatory, it’s all about keeping the warmth in. Thermal energy can’t escape a greenhouse because the translucent “walls” block the sunlight, yet heat from the sun warms the ground inside, which in turn warms the air. To combat excessive heat, a greenhouse can be used to generate or manage an atmosphere that is more conducive to plant growth by installing a cooling device.
Types of Greenhouses
Where you live and what you intend to plant will dictate the sort of greenhouse you need to purchase. Greenhouses can be classified in a number of different ways.
The following types of constructions can be classified according to their sensitivity to changes in ambient temperature:
Houses That Aren’t Heated (Temperature: Falls below freezing) Temperatures can fall below freezing in this greenhouse because there is no supplementary heat source installed. Cold buildings are designed to lengthen the growing season by allowing crops to start earlier in the spring and to grow longer in the fall.
Awe-Inspiring Residences (Temperature: 45-50F) Plants that succumb to the cold will be able to survive in this type of greenhouse, which keeps temperatures above zero.
Temperature: 55F Allows for a wider variety of plants to withstand the cold winters in a warmer environment.
Toxic Homes – (Temperature: above 60F) Tropical plants are cared for in warm greenhouses. Supplemental heat is needed to keep them warm.
There are numerous subtypes within each of these broad categories. Greenhouses can range from the simplest to the most complicated. From temperature to water and moisture levels, precise control may be achieved when more technology is used. Insect-proof greenhouses can also be built without walls or screens to keep out pests, such as shade greenhouses.
greenhouses can be judged on the basis of their style of construction as well It’s time to have some fun. A-Frame, Dome, Gothic (arched), Lean-To (may even be made to use the wall of a home or garage as one side), and Quonset are some of the most common styles of greenhouse architecture.
Materials — For the home gardener, the options are nearly limitless. Price, aesthetics, and your intended use will all play a role in your decision. Both advantages and downsides can be found in every situation.
Wood (rots easily), aluminum, iron, and plastic are some of the materials that can be used to support the structure. Curved and flat roofs are available.
Fiberglass (may get discolored), plastic (cheaper but more effective), double-layered polyethylene (change every 2-3 years), PVC, and acrylic are some of the other options (very expensive).
Environmental Control Options – Your budget will have an effect on what you can do in this regard. In a greenhouse, automatic controls are great, but they are also more expensive. Your options for heating equipment include a simple space heater, forced-air heat, radiant heat, steam or hot-water systems, as well as soil heating pipes underneath plants. For larger greenhouses, automatic watering systems are a plus. For the health of your plants, it is also important to arrange for ventilation.
Some Pros and Cons
Options for environmental control – Your budget will have an effect on your options in this area. Greenhouses benefit greatly from automatic controls, but these are more expensive. Space heaters, forced air heating systems, radiant heating systems, steam heating systems, hot water heating systems, and soil heating pipes under plants are all viable heating solutions. Automated watering systems for greenhouses with a lot of space are a plus. Your plants’ health is also dependent on proper ventilation planning.
The Benefits of a Greenhouse:
- Vegetables and fruits that are in season
- Affordability and success rates for organ transplants
- All year round, you’ll be able to get your hands on fresh-cut flowers
- A cozy retreat in the midst of a dreary winter
- To be able to develop things that you otherwise wouldn’t be able to (exotic flowers, tropical fruit)
- As a result, there will be no more conflicts with squirrels and other pests.
- Keep doing what you enjoy for longer periods of time. Enhance a landscape’s beauty and appeal
The Disadvantages of a Greenhouse:
- Building a home can be pricey.
- Heating a home can be a costly endeavor.
- Maintenance and care are required on a regular basis
- Could raise utility and water costs
- This might diminish the overall beauty of a garden.
