Now that legalization is making its way across the world, there are a lot more people who are now considering their options for growing a marijuana plant at home. In Canada, it is now legal to possess up to 4 pot plants per household without fear of legal repercussions, so they no longer have to be hidden from the prying eyes of nosy neighbors.

Though the weed plant is known for its durability and ability to thrive in some less than ideal conditions, that doesn’t mean that you can or should try to grow a marijuana plant just anywhere. You might have some luck with a hearty harvest one year and lose the entire crop the next thanks to good old mother nature.

Since it has long been common knowledge that many black market dealers have been growing their weed plant field alongside farmers corn and bush for years, it might seem strange to make such cozy accommodations for your maturing marijuana plant, but there are a few good reasons that you might want to consider investing in a greenhouse.

It doesn’t have to cost a fortune either as a simple frame that attaches older windows can be more than enough, and they will still provide a boost to your chances of success, regardless of how fancy they may or may not look.

10 reasons why you should learn how to grow weed in a greenhouse

Every master grower is going to have their own way of doing things. Some swear by grow tents and windowsills, while others prefer a more controllable and contained environment. Though there is no best way to grow cannabis, there are some safer and more efficient ways to produce a hearty yield with the least amount of risk. Here are just a few of the benefits that can come from using a greenhouse to house your precious marijuana plant all year long.

1. Heat

The marijuana plant is a common sight in cooler regions these days, but that was not always the case. Most of the oldest original landrace strains hail from countries with a warmer than average climate. Though marijuana might still grow in areas like Canada with a shorter growing season, the time you have to work with is unforgiving and limited. With a greenhouse, you can provide the warm temperatures that every weed plant craves all year long.

2. Humidity

This species thrives in hot, humid areas thanks to the boost that the thin layer of water provides to a marijuana plant. A healthy level of humidity allows for a better rate of photosynthesis, which is a process that plant uses to turn natural elements and nutrients into food. A greenhouse can help to maintain ideal humidity levels by placing a small container of water in the same area as the weed plant. The extreme heat will then work to evaporate the liquid, turning it into a thick cloud of perfect moisture for your weed plant.

3. Moisture

Not to be confused with humidity, which is in the air, but soil moisture is almost as critical to the development of your marijuana plant. It can be a challenge, particularly for traveling business people to be home often enough to water their weed plant, which can lead to a disappointment, returning home to a shriveled up and dead or dying marijuana plant. A sealed greenhouse can help to prevent this and allow for a reduction in the frequency of water needed by up to 70%. So, if you like to go on vacation, or travel a lot for work, then a greenhouse might be your best choice.

4. Pests

Cannabis plant terpenes are excellent for protection from vicious bugs and other pests that like to eat or reproduce on sweeter tasting plant species. Though the weed plant has a pungent smell that manages to keep many away, the rest enjoy munching on the leaves for their sweet and highly nutritious oils. It can be challenging to protect your plants both indoors and outdoors from pests, as they are most commonly found on your typical house plant. A greenhouse can help to protect your weed plant by sealing out the pesky critters so that they never gain access to its delicious juices in the first place.

5. Disease

Most people don’t view the marijuana plant in the same way as they do other species, but the truth is that greenery is just as susceptible to disease as any other living thing. A greenhouse can help to protect your weed plant from dangerous and often fatal diseases and illness and can also make it easier to treat your plants if they do happen to catch something contagious.

6. Expand whenever necessary

One of the biggest downsides to growing indoors or using grow tents is that you are limited to a very specific size that often cannot be stretched to accommodate an extra marijuana plant. However, with a few more panes of glass, or the initial investment into an expanding model, a greenhouse can be made into any size that you could ever want or need along the way.

7. Protection from the harsher elements

Whether it’s strong winds, rain, hail, frost or any other naturally occurring environmental conditions that could damage your marijuana plant, these risks are all present when a weed plant is left alone in nature. Though this species is resilient, and many types of marijuana are known for their short, thick, and robust features that are meant to withstand such a beating, one broken stem could cost you all your hard work. You may not be able to control the weather, but the addition of a greenhouse can offer an unbeatable layer of protection against all of these dangers and more, which can help growers that are cultivating more delicate cannabis strains.

8. Maximize the potential of the natural UV rays from the sun to save on hydro

Too many windows in a home can make it difficult to cool, and annoying for homeowners who need to seek out curtains to cover them all, which is the reason why grow lights are almost always necessary for growing marijuana indoors. For the most part, the glare from the sun is something that people try to keep out, which can increase the cost of your initial investment, along with maintenance and utility bills. A greenhouse doesn’t require electricity, or even running water to create the ideal environment for your weed plant to thrive.

9. Less theft

If you can bring a weed plant to full maturity outdoors, then you will be running the risk of having it stolen. Since many people rent or do not have the additional space to dedicate to the task, most are left with few other options. Luckily greenhouses, even the smallest versions, can be cemented into the ground and locked which can help to keep your marijuana plant both safe and secure.

10. Higher rates of success

The benefits of using a greenhouse extend beyond being useful for those that are just learning how to grow weed as the addition can make a significant difference in the amount of maintenance a crop requires, how big the buds on your weed plant get, and ultimately, how substantial of a yield the growing season provides. This is the reason why it is highly recommended to use this method whenever possible, over other, more common grow boxes that remain exposed and susceptible to attack from all of the things that are listed here and more.

These benefits are fantastic, but the very best reason to buy a greenhouse for your cannabis is that it can provide you with the opportunity to grow all year long if designed correctly, which can help you to kick a consistent supply of marijuana plant products.
