Wall fan space?

I want to build a 12x7 foot room for a 4x8 tray.

How much room do wall fans need to work good? Will 1.5' of clearance all around the tray to the wall be enough? I was thinking one fan per wall or two on each long side. I really want to move away for tents lol

The air blasting directly on your plants should be limited to a gentle breeze. I like to put my wall fans at a height below the lighting but above the canopy and then more on the ground below the canopy. Have some oscillating fans (pedestal kind) that are at plant height blowing between my rows but I have space for that.

You may find that using more fans of smaller size does a better job but the downside is replacing dead ones. The trick nowdays is finding a fan that lasts, I am always replacing fans. The more you have, the more there are to fail. I probably replace one a month. The only fans I have that last are the commercial ones I lucked into on Amazon but they are big. I mounted them on strut channel so I could slide them up and down as the plants grow.

Do you find these to be worth the price given the durability?

My Hurricane's have been going strong for the last couple years, could have gotten lucky I suppose.

I should add that they move a LOT of air, even on low speed. I typically use a variac and set them on slow then turn them down to around 80 - 90 volts to slow them a little more.

Ain’t nothing like reviving a old thread. Recently I’ve brought the cheapest 16inch wall fans on Amazon, 16 inch hurricane fans, and 2 metal fans that doesn’t turn. I was avoiding the 160$ priced fans. I have 2 grow spaces that are atleast 20 feet long. Should I bite the bullet and get atleast one of those that was suggested for each space

Hey Ren, what height do you keep your fans? I’ve been told to keep my fans in the space between the top of the canopy and the lights

What kind of lights do you have? I try to have my fans blowing on the legs and a small fan blow over the top of the canopy
