Fans for 60x60x140cm growbox

Hello ppl, i just bought growbox 60x60x140cm.
Need help about fans? How much and how bigg cfm fans do i need for that grow box to keep temp optimal?

I will run 140w LED UFO + few CFLs on one autoflower, i hope its enought info..

this depends on the area u live in ..........what temp the intake comes in at and how the air flows around your grow area


we can not help u
need to know ..........what is the intake air temp at..........how many plants and what method u plan to grow .......do u have fans blowing air around inside the grow area.......are u going with a powered intake or a passive intake

Using Led and Cfls I would think you could have a simple exhaust above you light and a passive down low , with a fan oscillating across your fans , depending on your ambient temps you could again open another passive intake (low) or mount a fan and see what it does.

One plant in 60x60x140cm, growbox is located in livingroom just near the window (so circulation of fresh air is good). The temperature in living room betwen night/day oscillate for 64F to 86F.
My plan is to put 150CFM exaust fan with carbon filter on top and intake at bottom of growbox with 100CFM.

u should be ok but u want to keep that intake air temp near 70 ............u are looking at a 8 to 11 degree different from the intake to the exhaust


80 degrees THC degrades faster .......if u can u want to keep it at 78 highest 75 does very well for me

depends on your country if u are in china they see everything u write ...........japan and the other places u are safe until u are pushing massive weight or u use to many keywords

as for this place i am not sure where it is run from .........if the ppl are smart they have the servers set up were the laws are on our side so everything is protected or set it up outside any place with active treaties .........several countries that do not agree with international intenet laws and will not honor any legal paper served on them

and so we never hear from fmp again lol jk personally I think 120mm computer fans would work in that small of an area they move 70cfm a piece and youcan get ten paks on amazon for under twenty dollars

I have the exact size tent. Get a 10 inch can fan position it to exhaust out the top. Use ten inch ducting to the carbon filter which can rest on the top of the tent this gives you more room but still kills the odor. This easily cools my 600 watt led. I use an interior clip fan to regulate humidity and get some air for the ladies. A passive exhaust is fine since the 10 inch csn fan actually creates a vacume so it does the entire job in a while 2x2. Defo reccomend an led... ive done both and for a 2x2 its amazing.

Okies, thx guys
