closet grow/ possible with no ventilation?

[Mr T]

yeah...id go with the fans..intake and out take. if u keep the doors closed this reduces pests etc...try to prepare ur self so that everything runs smootly when it all up and running. the last thing i would want is to mess things up when im in the groove...ha ha ha. i think i go with babystarbud advise. hope all goes well.

you def need some form of vent...more for the heat....but just think when there is no ventilation...NO CO2! so you plants choke when they use it all up and dont have anything to replace it

a good fan will replace the air in the whole cab 3 times a minute or 1 time very 3 minutes, i cant remeber off hand

with that much light i wouldnt go anything less than a 465CFM fan id even go higher just to make sure you can never have enough exhaust power

Closet grows with little ventilation can be done; I'm doing it now myself with a plant I couldn't bear to kill...but it's a beotch, so I spent some moolah on a grow tent and a real light and fan and stuff, because dealing with this closet is irritating me no end. I've got around 520 watts (real watts) of CFLs in a tiny-ass closet, using a $20 box fan for cooling, with the door a third open. It's working. I could probably get it all the way through flowering this way, but it's just too much of a pain in the ass, and it's pissing me off. Mainly, the plant in there is getting too big for the closet (it's 46" tall now, counting the pot), after a week in flowering (so it's going to grow quite a bit more).
