prob not, as stinky said not enough head room, with the 1000watt and size of the pots you only have about 2' of growing plant material, thats not good in my eyes either

need more height .6' should be doable

as for the 4x4 you should be getting way over 50watts per square foot which is excellent
texas grass Reviewed by texas grass on . Has anyone? Greetings all. Has anyone had experience growing in a 4x4x4 box with 1000W HID in an air cooled hood reflector (with glass)? I've been reading and reading until my eyes bleed and can find nothing. I'm kinda stumped on ventilation. Thanks for your time. Peace and unity. Rating: 5
