Having a fan in your grow tent serves different purposes. If it is used outlandishly without an expert user, it might affect your crops’ progress. One of the important questions usually asked when it comes to fans’ subject is how many are ideal to have in a grow space.

The ideal number of fans that should be in your grow tent is about two. Having a maximum of two would provide the needed condition that you need. However, we still say that your tent’s size is a factor that affects the number of fans one can use.

How often should I exhaust my grow room?

If you grow plants in a room or grow space stuffy or filled with stagnant air, you will get a poor yield from the crops due to the lack of fresh air. Exhausting the room lets you force out stagnant and not fresh air to let in a fresh one free from allergens.

Do I need air intake in my Grow Tent?

Yes, it would be best to have air intake because you exhaust air out of the system. The exhausted air from the grow tents are usually stagnant and not favorable for growing plants. However, when air has been dispersed from the grow tent, there is a need to let in a fresh one to make your crops grow to be good.

This way, the air that gets to be taken into the grow tent would benefit the crops.

Can I leave my fan on 24/7?

Your fan in your grow tent should be left working twenty-four hours a day. Because of the temperature in the grow, the tent needs to be kept at an ideal level. You would have to let it on. However, you should know when to stop or reduce the fan’s speed at a later stage of your crops growing.
