i have access to a closit thats about 18 inches deep, 36 inches wide, and 8 feet tall. I could fit 5-6 plants in there, but what about a 600 watt light? With a euro reflector? I know i realy only need a 250 watt for that space 5sf but six plants 600 watts sounds ideal. so if i go with 6 inch exhaust vents am i being unrealistic? im having trouble finding a journal about a closit grower with the same size closit. plus this is a row house/ town house, type situation where the closit is in a upstairs bedroom. would i be better off useing the hight of the closit and sectioning off into two 4 foot sections top and bottum with a 250 watt hps for flowering and cfls for vedge? what would you do?
I'd say two 4 foot compartments. One for flowering, one for vegging. Maybe a 150-250 watt HPS bulb for flowering, with 1-3 plants in each compartment. For the Veg compartment, I'd go about 100 watts of CFLs, whether it's 25 watts x 4 or 32 watts x 3 or 48 watts x 2 etc, it shouldn't matter *that* much for vegging.
If you look around some people are doing some AMAZING STUFF with a 250w HPS for flowering. Don't know the name of the guy but he grew one plant, and got 7 oz dried with a 250 HPS. And if you have extra lighting you could b all good.
