two hps are better... just make sure to get quality horticulture bulbs, with blue spectrum... this will make all the difference... of course if i was you, i would go with one 1000, which will end up making about the same heat as two ballasted 400's

and of course if you could two hps, and 6 hours of extra mh in the middle of the 12, because more par'd lumens, is always key to a better harvest.

but you could be stepping on your dick if the heat isn't controlled

well i got 2 flowering rooms one with a 1000 watt on a 4 plant 4 x 5 canopy and i have another flowering room same size with 7 on a sea of green set up. which i had a 400 mh and a 400 hps becuase that is all i had but my boy jsut gave me this 1000 watt so i took the two 400 hps i had and i just moved one to the 400 hps and mh side. but do nto have the mh running any more i set it up on a timer to go on 6 hours in the middle of the 12 to i guess help with full spectrum. temp is not a issue i keep is around 60 to 75. sometimes alittle colder at night for that purple tint.

thanks homie


i got two master purple kush plantes that a like 4 weeks old and just so small in soil can i carefully take them out clean off the roots and put them in deep water hydro to get them growing quicker? or is that to much stress
i got them in my 2nd flowering room they are like 5 inches and under 12 12 i would like them to do better then what they are doing now
