Tryin to not use my other fan. That wud be 3 fans on. My 8 inch on filter 1000cmf Reductions bends filter 700cmf I have 2x 8 inch intake holes. Is that enough the rule says 3 or 4 times more holes than your intake Does that mean my 2 8inch isnt enough... So better swap to my 6inch ducting and use my 6 inch fan ? Lighta are in seperate coolhood fan setup
I'm hps on a 4 inch vent tube and thats way too small lucky its cold here but I'm moving to led so venting aint gonna be an issue check this link if in doubt add more the vent link is the best on the web Ventilation 101 - International Cannagraphic Magazine Forums good luck
Switching to led from hps really helped me with temperature maintenance. That will be a good move for a great Grower!
My hoods are 1200watt magnums there on a 6inch 400cmf in and out. This is literatly just the tent its self. So i have a 8inch extractor on a filter.and smscom at 80% So she gone from 1000 to filter 850 bends 700 and 80% max so like 500cmf. And when cool down to 40% which is 300 and this is most the time i run at 21c. And nornaly i use a 6inch 400cmf intake fan. However when on low mode this fan makes posative preassure even on smscom. Jusy wondered if 2x 8inch passives would replace it . Seems like it would however the tent collappses on full power Cant win.. Gona try 6inch intake 1 vent passive the other and increase the airmovement. Will be doing double air changes than reccomended tho. Co2 will be low . Hmhmmmmmhmh Putting the 6 on the 8inch filter instead ? Run 2 passive 8 then. Keep the 8 incase heatwaves Fuck knows
