Hey everyone ive been dooing a lot of reading here on the site and found it to be a wealth of information. Im going to start growing and i need a little advice. Ive planned a grow room 5'x3'x2' painted white using 2x4' shop lights with 2 tubes each. these are going on the sides of the box(good idea?). Im going for cool white bulbs for the veg and warm for the flower. Im going to go as many lumens as possibe. Also im going for 3 CFL's probably 40w on the top. Do you think this will be enough light for 2-4 plants? Heat issues? I cant have ventalation b/c theres no outside access. I figured id open it everyday to vent. Also dont really have acess to computer fans(live on an island). Maybe a oscalating fan? Let me know what you all think.

Thanks
b

You don't have access to computer fans? I'm sorry but are you using a typewriter and mailed this message to rollitup?
Tubes are okay for vegging but for flowering they are a waste of power.

Ventilation is key. Not just for heat though. Plants get there energy by taking in light (top of leaf) and processing Co2 to o2 (bottom of leaf). With non moving air it takes a plant about an hour to use the Co2 that is underneath the leaf. So you have to bring in fresh air unless you are using Co2 and even then you want it to be moving in the room.

Yeah like cloudflyer said plants regulate small openings, stomata, on leaf undersides to allow CO2 to enter and oxygen to exit.....

Also. Plants have five basic needs. Each one amounts 20 percent of a plants ability to grow to its maximum potential. When all of these needs are met at the maximum, the result is maximum growth (20% x 5= 100%)! If one of the needs arrives at only 15 percent, all growth is impaired equally (15% x 5= 75%). If two or more of the basic need are not met, growth slows quickly. Even with the best hydroponic system money can buy, in a garden where relative-air humidity is 80 percent when it should be about 50 percent, growth will be limited. The dollars and high hopes invested in a hydroponic system can easily be 'dashed' in a cloud of hot, humid air.
