Alright i placed my order: Homebox L Digital Electronic 600 watt HPS & MH Ballast SunMaster 600 Watt Super HPS Deluxe Bulb Mini SunSoaker Reflector Should I buy a 600w MH bulb for the earlier stages or will that be too strong of a light? Other then that il just need to get some fans and a carbon filter correct? Roughly the size of the Homebox L is 3.5' x 3.5' x 6.5' so what size fan will be needed? Thanks for all your help, because of it ill be hoping to start growing when my seeds arrive in the next week or so. Also if not the 600w MH, im assuming the HPS would also be too much, so what does that leave me with? Thanks once again for all your help.
get a few cfls (daylight) to start your seedlings under if you are doing a cabinet you'll need a lot of ventilation before you can put plants in it and it should completely cycle the air through in just a few minutes the light might also need its own cooling (get a fan rated at 4 times what the interior of the cabinet is and run it on a dimmer)
