Growing your plants inside a grow tent is quite a challenging task as you need to ensure that everything from the size of the grow tent to the temperature is perfect. Even a small mistake can lead to the entire batch of marijuana plants getting a major hit in their growth! However, the use of grow tents is getting increasingly popular, especially as anti-marijuana laws are being relaxed all over the US and people have begun to grow their own weed. In this article, we will take a closer look at how to increase humidity in a grow tent.
However, before that, one needs to understand what humidity exactly means and why is it important for the plants – especially cannabis plants. We will then look at some of the best methods to increase humidity inside a grow tent, followed by some methods to even reduce the humidity! Humidity is extremely important for healthy growth of marijuana plants and this is why many people prefer to grow their weed indoors inside grow tents rather than outdoors because they have a much better control over the growth when it is done in such a controlled environment. Here’s a closer look:
What is Humidity?
Before we begin with anything else, it is critical for growers to understand the basic question – what is humidity? In the most basic terms, Humidity is essentially the concentration of water vapor in the atmosphere. The higher the humidity, the sweatier you feel. The lower the humidity, the lesser the water vapor in the atmosphere. This is something which is very important for the growth of plants and particularly the marijuana plants.
Why is Humidity Important for your Plants?
In order to understand humidity and its importance for your plants, you need to understand a little bit of plant biology. As important as light, heat and air are for the survival of plants, water also plays a very critical role. For plants to grow (including cannabis, but also other plants such as kava or tobacco), a lot of water is actually absorbed by them through the roots. However, a significant amount of water can also be absorbed by plants via the leaves and the stem.
When humidity is high inside a grow tent, it basically means that the air is holding more water vapor in it. Plants can use stomata, which are small pores on their leaves to absorb this water vapor and provide water for themselves! Simply speaking, conditions where the humidity around the plants is higher is actually beneficial for the growth of the plant, especially in the stages before flowering begins.
Humidity and Cannabis: How Much Humidity Do You Need to grow Weed?
Humidity is important for the growth of all plants but particularly for growing cannabis! This is because when you finally know how to control the humidity levels inside your grow tent, you can increase or decrease the humidity based on your plant’s grow cycle. The basic funda that one needs to know here is that the higher the humidity, the more the plant will absorb water from the leaves and if the humidity levels are lower, the more it will absorb water from the roots.
Basically, you need to ensure that the humidity levels are higher during the early growth phases but lower during the later growth (Flowering) phase because that is the time that the plant should begin to absorb water from the roots as all the required nutrients that you mix to the soil would then be absorbed properly via the roots. Furthermore, by adjusting the nutrient levels and the humidity, you can also increase resin production – basically giving you a greater amount of control over the kind of ‘high’ that your plant gives you with the creation of extra-potent buds. Hence, understanding how to increase humidity in a grow tent (and even decreasing it) is very important for those looking forward to grow weed!
How to Increase Humidity in a Grow Tent?
How to Decrease Humidity in a Grow Tent?
Here are some of the most commonly asked questions when it comes to increasing the humidity levels inside a grow tent.
Why is Low Humidity Bad for Plants?
Low humidity levels are bad for the growth of the plants for multiple reasons. First off, it is because plants use water not only for their growth, but also as a coolant. Hence, if the temperature is warm but the air is dry, the plants will have a hard time transpiring and their vascular structure will get damaged. Plants getting dehydrated leads to the stomata getting closed and once that happens, the plant has a hard time ‘breathing’. Furthermore, when humidity levels are low, plants tend to take more water from the roots and that may lead to an excessive absorption of nutrients that might cause the tips of the leaves to ‘burn out’. Molds might also begin to appear in case of excessively low-humidity conditions.
Is it Bad for Plants to Have Too High Humidity?
High levels of humidity are good, but getting the levels to ‘too high’ is going to be detrimental to the growth of the cannabis plants. This is because having very high humidity levels can result in the plants getting oedema which happens when plants absorb more water than they can use – causing in pressure being built up inside the leaves and plant cells begin to burst.
There’s also the risk of a soft growth in plants when the humidity levels are too high. Moreover, there’s also risks of foliar diseases as well as root diseases happening to the plant. In addition to that, the higher the amount of humidity, the lesser water goes through the roots and the lesser the water goes through roots, the lesser the nutrients go up the plants, resulting in a deficiency in the nutrient content which is important for the plant’s growth, especially in the flowering stages.
We hope this article helped you in learning about how to increase humidity in a grow tent so that you get to the optimal levels! Too much or too less of anything is bad and humidity is just the prime example of this! Use these techniques while growing weed in your grow tent to ensure proper humidity levels. We also recommend pro-growers to try out playing with the resins and do let us know if it did help in you getting a better ‘high’ with the bud!
