Whether it is to obtain more crops in a year, to not depend on the inclemency of the climate, to get a better quality cannabis or to lower the cost of cultivation, many cannabis growers are betting on the technique of light deprivation in greenhouses and best stealth grow box. This method is used to force cannabis plants to flower regardless of the time of year. An alternative that is also healthy for the environment.

As the legalization of marijuana continues to gain ground around the world, many cannabis growers are trying to find ways to maximize the yield of their crops so they can increase their profits and be more competitive in this booming market. This is why new techniques are emerging more and more frequently to get more out of the investment made. In any case, the first question you should ask yourself is whether you opt for an indoor or outdoor crop.

Many people choose to plant and care for their plants outdoors, thinking that if they have to set up an ‘indoor’ growing space they will have to invest more budget and resources. However, there are techniques, resources and tools to optimize a plantation and get a lot out of it with little investment. One of the techniques we can use for this is the deprivation of light. If, when it grows in the middle of nature, cannabis manages to adapt to changing weather conditions, when there is more or less natural light, and it manages to get by, why shouldn’t this also happen, for example, in a greenhouse environment?

This is what this method is all about. It involves using opaque curtains on the walls and ceiling of the greenhouse to completely obscure the room and deprive the plants growing inside of sunlight. In this way, the passage from one season to another can be imitated perfectly and always in detail, while at the same time forcing the plants to flower regardless of the time of the year. This will allow us to obtain more harvests in a single year and, therefore, make the investment made in acclimatizing the greenhouse much more profitable.

Different ways to put it into practice, for the same purpose

There are different methods to implement light deprivation in our marijuana cultivation. The simplest way involves placing a large tarp over the plantation, which the grower has to remove and put up at very specific intervals. In this way he can provoke the flowering, imposing cycles of 12 hours of light and the same time of total and absolute darkness. This is the most affordable and economical way, but it is also the one that demands more commitment and dedication from the grower. In addition, it is not always easy to move these canvases, so perhaps one person cannot perform this task. So if two or more people have to agree on a schedule and move the tarp, there are too many arguments that this system will not work.

That is why most of those who bet on the light deprivation method decide to invest a few more euros to implement an automatic system that allows to set the hours in which to prevent sunlight from entering the crop, either with a tarp or curtains, and those moments of the day when it is removed so that the plants receive their ration of light. If everything is set correctly and the timer does not fail, we can be calm and completely unconcerned that everything goes well.

In this sense, we must pay close attention to the climatic conditions of the place where we install our greenhouse, in order to avoid setbacks. For example, if you are in a place where the wind usually blows, the curtains or the canvas should be installed inside the room to prevent them from moving because of the wind gusts and the light ends up reaching our cannabis plants when it should not.

Benefits of the light deprivation system

There are many and varied benefits that marijuana growers have discovered over the years with the implementation of this system which consists, as you have already deduced, in trying to deceive the plants by simulating different climatic situations. One of the things that will tempt many to bet on this system is that they will be able to enjoy a year-round production. Without a doubt, increasing the yield and obtaining healthy crops regardless of the season is the main argument that many use to resort to light deprivation.

When those who grow outdoors are still waiting for the buds of their plants to mature, the crop we have subjected to this method will already be harvested and ready to be tasted. This also gives growers more scope to conduct certain tests and even experiment with new varieties.

Almost without realising it, we will also be contributing to the care of the environment. While it’s true that growing cannabis indoors requires more energy, environmentalists and other experts are seeing how greenhouses equipped with light deprivation systems can not only be beneficial for rapid plant growth but also for reducing carbon emissions into the atmosphere. A study by Bruce Bugbee, a professor of crop physiology at Utah State University, has shown that greenhouses use only about one-third of the energy required by an indoor crop. That’s nothing.

And because it requires less energy, you know, it also lowers the cost of maintaining our crop. Although there will be an initial outlay, especially if we want to automate the whole process as we mentioned before (so that we don’t have to spend so much time on cultivation), the truth is that we will see how the costs will be significantly reduced.

Finally, we must add that since we installed a system to automatically control the light that comes to our cannabis plantation, we can take advantage to create a perfectly controlled environment that allows us not to lose detail of the temperature, ventilation and other factors, so you get a better quality marijuana. Far from the problems and unforeseen events that can arise when growing outdoors, in a greenhouse we can have everything under control, so that nothing prevents us from enjoying the fruits of our plants throughout the year.

For all these reasons, reducing the amount of light that reaches our crops by means of this technique can be a very favourable alternative for our plants, for the environment and, of course, for our pockets. Do you dare to try it?
