Building a grow-operation is a serious undertaking. When we first entered the legal cannabis market, we realized finding a light deprivation greenhouse company we could trust, and a construction company capable of handling our project was a very difficult undertaking for us.

We have since made a point to connect with the best greenhouse, commercial greenhouses, and steel building construction companies in the industry.

No problem, we can help you build what you already bought, or customize your current setup to handle various sized crops you’ll be managing.

A greenhouse is a building that is constructed of either glass or a thick plastic material. Some have retractable sides, adjustable light sections, and offer a variety of protective barriers for agricultural farms. In this case, they are used for growing cannabis and or hemp in legal cannabis states.

The newest type of grow-house on the market, is (as of 2017-18) a light deprivation green house. These are either manually operated or automatic, and have adjustable covers on the sides of the structure which are retractable. The bonus to this is the grower and or farm, has better control over the amount of sun exposure their crop gets, thus being able to control the grow and when they would like their cannabis or hemp to flower.

This is a common commercial greenhouse technology, and is used for many plants that benefit from adjusted daylight hours- including poinsettias, kalanchoes, and chrysanthemums. 

Vertical and horizontal curtains, light traps on fans, and more help cannabis growers use economical commercial greenhouse technology to adjust the environment inside the cannabis greenhouse to the ideal plant environment.

Outside the cannabis industry, light deprivation curtains are referred to as “blackout curtains”. 

Discount Pharms does not supply the greenhouse or the construction work. We work with companies throughout the nation in all legal cannabis states who supply the greenhouses, and also contractors local to each area, who are capable of building the greenhouses. We do this because we realized the companies who sell the greenhouses are not always suited to be able to construct the greenhouse, therefore a big fall-off between the farms having a successful grow due to structural issues was happening and it needed to be fixed asap.

We will process your information and pass  to the most appropriate company and or construction personnel in your area.

We help farms plan the grow process from end to end. It is extremely important to utilize every portion of licensed space on your property to accomodate an important process, as lack of planning can result in not enough space for product to dry, be stored, or places to mitigate bugs and decontaminate before entering the grow itself. Russet mites were a killer to many farms over the last few years, and these are all items we take into consideration when planning out a grow.

Yes, but it isn’t that hemp won’t grow in the United States. The issue is that couldn’t legally grow it in the United States until recently. 

Hemp is the low THC (the component that gets you high) sister to marijuana. 

And with a THC content of 0.3 percent or less in Hemp plants, you simply can’t get high from smoking or ingesting them. 

Yet it still remains a Schedule I drug along with heroin and marijuana that can reach 30 percent or more THC.

If you’re trying to grow 10,000 hemp plants, it will be much easier to find space for those outdoors instead of indoors. 

However, at the end of the day, it comes down to personal preference, and your available resources.

But Hemp plants can be grown indoors just like their cannabis counterparts.

When it comes to lighting a greenhouse, nothing works better than natural light. 

If you use your greenhouse to grow plants in the winter, or if the structure or placement of your greenhouse limits the light that comes in, you may need a supplemental light source. 

To add extra light, you’ll need to purchase either High-Pressure Sodium or Metal Halide Lamps with the proper ballasts, or and LED lighting system.

But be aware that using the wrong kind of light can quickly stunt a plants growth if used at the wrong part of the grow cycle.

Like outdoor cannabis farming, greenhouse cultivation benefits greatly from free sunlight. 

And like indoor cultivation, a greenhouse grow-op completely eliminates crop damage from severe weather like wind, rain, and hail. 

Greenhouses also gives growers and strain breeders a significant degree of environmental control, which allows them to extend the natural growing season for higher quality, and larger yields come harvest-time.

The worst thing you could ever do is let your outdoor plants freeze during the cold months. 

How do you stop this?- Bring them indoors!

Growing cannabis or hemp in greenhouses is a great way to cultivate these amazing plants year-round, and keep them alive in any weather condition. 

You also get the benefit of a free light/energy source that naturally changes to the right light spectrum for optimal growth.

There’s tons of advantages, including but not limited to…

-Being able to grow hemp or cannabis year-round… this is great because hemp can usually only be harvested once a year.

-Having fewer pest problems than an outdoor grow-op… this is much easier to manage in a controlled environment, versus having to deal with an almost limitless amount of variables when it comes to plants being outside.
