Marijuana Greenhouse Farm

Having a personal greenhouse tells about how much you love your crop.

It’s like you are always willing to travel one further mile to build an ideal environment if nature doesn’t support it.

And this enthusiasm has gotten fancy with weed growers as they devise more methods for developing a legit ecosystem in the form of marijuana greenhouse.

That’s right— growing marijuana in a greenhouse has become popular in the past decade because 

  1. the authorities have mellowed down with their strict laws regarding weed cultivation in the past few years.
  2. the marijuana businesses have taken a whole new dimensions.

You could also own this sassy-green strain in your backyard or your farmhouse by practising this best greenhouse guide for marijuana.

Considering you have trampled all over the weed regulations in your area, let’s find out how to erect an outdoor marijuana greenhouse.

Building a greenhouse

Fixing a plank of land

Obviously, you can’t have greenhouse unless you have some space for the crop.

But unlike what it’s believed/shown; you can construct a greenhouse in a plank as small as 3-meter square.

In fact, a lot of people have resorted to mini greenhouses right in their houses.

So without further ado, start building your baby/mini-greenhouse because it’s the most cost-efficient way to drag some green blades.

Balancing the utility and the fancy

The best weed strain comes out with utilitarian approach rather than being too obsessed with fancy.

Just think of nature— it produces impeccable cannabis strain with simplicity.

You should make a checklist of challenges which you may face in all weathers, and visit all the problems one by one.

You can surely go for a fancy design only when you aren’t trading off the effectivity of simplicity.

Keep the room for changes because you might have to modify the plan later, henceforth don’t settle for anything which can’t be altered or changed.

Choosing the structural frame for cannabis in the greenhouse.

Choosing the right frame-type for cannabis is the most vital step in building a greenhouse.

You can try Matterhorn or freestanding greenhouses; however, sticking to the moderate structure can have lasting effects on the harvest.

The choice entirely lies on you whether you’d like to go for a wooden frame or metallic one; both have their pros and cons.

While the wood-based frame is easy to make and transit, the metallic frame has a better survival rate against catastrophes like wind, snow, fire, and pests.

Deciding on the hardware…

Well, the hardware detailing has to be one of the most vital equipments for growing quality marijuana indirectly.

It includes heavy finish nuts and bolts to fight extreme weather.

Quality polished hardware with proper fitting also ensures the safety of the greenhouse from sinking due to the load imbalance.

And the frame cover.

The frame cover is the cloth of your greenhouse— better known as glazing— shields the crop from direct sunlight and rain.

There are a variety of coverings which include polycarbonate, plastic sheet, polyethylene sheet, glass, fibre-glass.

Poly materials permit the short wavelength to penetrate the roof and block the long-wavelength from escaping it.

It could be damaging for you and your crop’s health.

Similarly, the glass cover can be fragile and heavy; however, it shows the best harvest.

You can fix on translucent fibre which has a long life and isn’t opaque as plastics; howbeit, you’ll have to get them replaced in a few years as UV radiation. 

Since cannabis strains have subcontinent belongings, your primary role is to replicate the environment for your greenhouse.

Producing a dry and warm climate depend on the type of cover you choose.

For better understanding, refer to the given chart.

Covering Material Diffusion Life
Glass It doesn’t diffuse the light If not for perilous catastrophe, it may survive for 30 years. 
Fiberglass It moderately diffuses the rays It doesn’t react with moisture, have no effect of corrosion, heat expansion, but may turn pale with intense UV exposure.
Polyethylene sheeting It diffuses the light Light-weight, brilliant insulation, and impervious to UV radiation.
Polycarbonate It diffuses the light Light-weight, lasts 15 to 20 years, loses light-transmitting ability due to UV discoloration, too stiff to be used for curved greenhouses

Putting the crop on ventilation…

The obvious purpose of having a greenhouse is to have control over temperature— as you may like depending on the weather condition.

Ventilation gives you the power to regulate the inner temperature at your will, especially when the required temperature is not as per your expectation.

Too much heating from evaporation can damage the strain.

So, you can cool down the cannabis produce with proper ventilation which includes methods like mechanical ventilation (sizing fans), shading, natural ventilation, blackouts, curtains, shutters, etc.

It’s an excellent way to capture moisture for the plant as that would need less water from your side.

You can use roman curtains and shutters to have some natural airflow.

Exhaust fans and hydroponic system such as plastic tube sprinkler can also maintain the required mist level in the system.

Convertible roofs have been one of the conventional ventilation methods for a long time now.

And the heating system when needed.

To what ventilation is for warmer temperature, the heating system is for the colder weather.

If your set-up hails from a bit colder place, you would need an effective heating system to force the budding spring out of the cannabis plant.

Generally, you should aim to maintain the temperature of cannabis greenhouse flicker around 70 to 80 degrees.

It’s not too hot, but mild enough to appease your plant’s growth.

In fact, the greenhouse effect is a cumulative heat produced by the sun in the system plus the heat released by the plant.

So, with the proper heating system, your plant will get to balance the humidity and heat in the colder temperature.

Convection tubes and heat pumps are potent heating devices.

Heaters such as propane burning devices increase the carbon dioxide in the greenhouse system, which enhances the plant growth.

Adding up the lighty-flair

See to it that trees and high-rise buildings don’t cover up your greenhouse.

In the case where natural light doesn’t reach your crop, use greenhouse lighting technique to propagate a consistent level of light throughout the year.

Here’s the catch while using fluorescent lighting in the house— you get the power to control the plant growth cycle.

If your greenhouse is overheated, you can cool it with ventilation and use different shades of lightings possessing different watts to control the outcome of cannabis which is known to be extremely sensitive to the timing of overall exposure.

To get the vegetative produce from the cannabis, you should be able to generate 70 watts per meter and PAR (photosynthetically active radiation) minimum should last more than 18 to 24 hours in a day. 

However, supplying 12 hours of light & cutting it down for another 12 hours will result in budding.

Hence, it’s imperative as a grower to make use of these lightings for the desired cannabis cultivation.

Environment control for fancy greenhouse.

If you are looking at how to build a marijuana greenhouse for business rather than personal use, you might have to nominate automatic environment controlling devices in the system.

These devices are advanced computer modules which suck up the frustration every time you have to adjust to the ever-changing temperature.

With the in-built thermostat in the device, you can make the crops behave as you want, without too much manual operation.

Keeping thieves off from your land.

There are two types of marijuana thieves— the general thieves and the thieves in suits.

I relate the second category with the authorities who don’t want to see you cultivating this beautiful hash.

You can keep the former category of thieves off from your marijuana land by deploying cannabis security devices like cameras and man’s best friends— dogs.

However, you can’t really do much with the second type of thief.

Hence, the onus falls on you to stop spreading words about your cultivation (the golden rule) and trying to keep it out of sight (the very reason which resulted in the concept of underground marijuana farm).

But make sure that you’re not retaliating too much to defend your crop in a manner it physically abuses others.

The case may tarnish your future as a grower and as a citizen at your place.


  • The infant or seedling marijuana positively reacts to 60 to 70% of humidity, and the adult crop responds well to 40% of moisture. You have to feed humidity based on its requirements.
  • Don’t trade off fresh air and natural light with underground marijuana farms. That would only hit your ranks. Instead, you can deploy a robust surveillance system to secure the greenhouse.
  • Maintain the temperature around 70 to 80 degrees (25 to 30-degree celsius), and use vents plus heating system to level up and down the warmth.
  • Use drip irrigation as your reliable hydroponic system for stationary cannabis strains and timely watering.
  • Mounting the CO2 generator in the greenhouse ecosystem will improve the growth of plants.
  • Understand your area and its environment before being too active about it.

Wrapping things up

Permute and combine several instances to get the best result if you aren’t an expert in building one for your personal use.

However, you can partner with greenhouse suppliers who have years of experience, and seek life-long guidance for your business.

So, what’s your favourite greenhouse experience?
