Grow tents may seem like the perfect alternative for those who can’t afford a grow box or want a growing environment that they can easily disassemble and move. While grow tents aren’t inherently bad, there are some dangers to be aware of to protect you and your plants.
Grow Tent Heat
One of the most common issues that can occur with grow tents are heat issues. Marijuana doesn’t like to be above 80F, if possible. Ideally, your grow lights should be tailored to the size of your grow tent; also, they should be placed the recommended distance away. Often, new growers will place powerful lights way too close to the plant, causing a lot of unnecessary heartbreak.
If your grow tent is too hot, your humidity will be too low. But there are other factors at play, such as the humidity in your local area, how much air flow you have and more. That is why we recommend a 4×4 grow tent. Do your research and keep this issue in mind.
Toxins in low quality and counterfeit grow tents
Because heat is a big ingredient in making sure you get the best out of your plants, it’s important to have a grow tent that’s made to withstand grow light heat. Unfortunately, many grow tents don’t come up to scratch, either because they are of a low-quality design or they are made to seem like a good brand of tent, but are actually counterfeit, often from China. (It’s like with ladies’ handbags…if you get it for cheaper than expected, it’s not Prada.)
Counterfeit tents are an especially big problem, because they’re often made to look like high quality grow tents. But once you start growing in them, the problems become obvious.
Signs of distress for your marijuana plant:
For starters, your plants will show mild signs of distress. You may think it’s you who’s doing something wrong. But then weirder things start happening, like your marijuana has turned strangely bright yellow. Symptoms of nutrient deficiency may also be apparent. And then your plants die.
This is one of the most frustrating issues even for veteran growers, and it’s only in the last few years that the problem has been truly pinpointed.
Beware of PVC
Many counterfeit grow tents are made with PVC (polyvinylchloride) or PU (polyurethane). You may be familiar with these materials, they may be elsewhere in your home with no issue. But they should never under any circumstance be in your grow tent.
The reason is these two chemicals give off toxic gasses, like chlorine, that are poisonous to both you and your plants. What happens is that even when your heat in your grow tent is perfectly tuned, it’s still too much for the PVC or PU to take. When exposed to heat, they put off the gasses, strangling your plants to death, essentially.
What you should look for in a grow tent:
The best grow tent material is easily PE (polyethylene). It’s stable when exposed to heat, so it’s not poisoning you or your cannabis. Even better, it’s recyclable, so it doesn’t negatively impact the environment. There are also Nylon-type tents and similar which are also non-toxic, so you do have quite a few options when it comes to buying a safe grow tent.
