Why Should  Use Inline Fans For Cannabis Grow Rooms

Marijuana has been frowned upon up until recently when people realized all the benefits it could have were much greater than the possible consequences. And that’s when it started being legal in a lot of states. This is good because now you can have your own grow room without having to worry about anyone else taking it away. It’s not really a bad thing to enjoy some from time to time. There are many products which help you grow better quality plants, as well as more plants.

Inline fans are the next big thing when it comes to growing weed, and they’re pretty useful.  They’ve also been fairly underestimated.  These little things can help you greatly, and they’re not to be messed with.This is because they’re essential for managing temperature and humidity in your grow room.

Without them, the whole operation can easily fall apart and your plants won’t grow well at all. Inline fans remove the excess of carbon dioxide which plants accumulates in a plant filled room and thereby stabilize the environment.

What’s more, the potential for overheating (and possible fires) due to the numerous lights we can find in grow rooms will be reduced greatly if you have an inline fan.

If you want to create a stress free area for your plants, which will surely help them grow, you’ll definitely want an inline fan to regulate the environment.

There are many models you can choose from, which is why it’s helpful to do some research before you choose your new companion. That’s where this article comes in handy. So if you want to learn more about inline fans for your grow room, have fun reading this article!

Inline Fans  Buyer’s Guide

Before you get your new fan, there are some things you should know, and certain features they possess which make them better. Without further ado:

The size of the grow area

Before anything else, you need to determine what size your area is. This is important because different sized fans will have different rates of air circulation, and you want optimal circulation in your room for the best results. Luckily, there is an easy formula to determine the ideal size for your room. All you have to do is multiply the height of the room by its width, length, and 1.25. It helps give you an idea how much air should be removed from the room.

The size of the grow area

The heat of the lights

Since some lights generate more heat than other, you’ll need to determine what kinds you’re using and then see which type of fan corresponds to that. HID lights tend to heat up the place more quickly, so in that case, you’ll need a fan that can handle and remove the heat, for example.

The heat of the hid lights

Diameter of the fan

As you may have noticed, fans come in various sizes. It’s not always easy to choose the diameter you need. After all, there are those of 4” up to those of 16”. If you want a safe bet, get a 6” diameter fan. That’s because the most common indoor set up will be to accommodate that size perfectly. If that happens not to work for you, you can simply get a converter instead of an entirely new fan.

Conclusion

As you may already know, there are a few things that are essential for successful marijuana growth, and one of those is definitely inline fans. They keep things fresh and the air moving, which we all know is essential for quality photosynthesis. Because let’s face it, no matter how much better marijuana is from other plants, it’s still a plant.

Remember that if you take good care of your plants, they will take good care of you, too. It’s also much better that you’re growing your own stuff because you never know where the one you buy comes from or what might be in it. This is a much safer alternative, and it can prove to be cheaper, too.

So look your fans wisely, as your plants will need them for sure. Once they’ve grown healthy and happy, you’ll be thankful that you decided to buy that inline fan.
There are plenty to choose from, so be free to take all the time you need to make the right decision for you.
Happy shopping!
