Best Top 8 Grow Tent Ventilation Kits Review 2019

grow tent ventilation kits

​For the dedicated and patient gardener an indoor grow tent is often the way to go; with an indoor grow tent you can maximize harvests for year around yields. Many of us see ourselves growing, fertilizing and harvesting our beloved plants in the tents controlled atmosphere. Yet it is that very atmosphere that we forget to build.

To optimize the growth of your plants inside your grow tent you need to consider ventilation. Through ventilation in your indoor grow tent you will control the temperature, moving the air around ensuring the plants nearest to the lights don’t burn and those at or near the tent edges don’t freeze; maintain the optimal limits of humidity rising from the plants preventing pests and diseases; lastly ventilation fans contribute necessary CO2 for the plants to consume.

Right now you’re thinking, this is great. I’ll just pop out and put in a ventilation fan right now, or maybe this weekend. Before you do I implore you to consider several things that require looking into before you purchase a ventilation fan.

First, the size of the room in your grow tent. Not all ventilation fans cover the same amount of space.

Second, think about the volume of growth. How large are your plants going to get? And, how fast will they reach full size?

Third, how much air will be moved? Different ventilation fans move different amounts of air through their various filters and ducts.

Fourth, look into exhaust efficiency. As I mentioned before you need CO2 to help feed your plants, only it must be just the right amount or you’ll kill them.

Lastly, think about where to place the ventilation fan. Will you need more than one?

​To my mind, the best of these options are the complete kits which contain all of the items you will require to set up your ventilation systems. Such as the VIVOSUN Air Filtration Kit, it’s compact and easy to assemble good for small grow tents and beginners into this type of gardening.
