400 hps + 400 mh or two 400 hps for my second flowering room?

basically that is my Q should i run two hps or one of each or 1200 watts do like 800 hps 12 and have the mh go on like couple times during the 12?

thanks.

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

how much room are you working with

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

i would just go with the 2 400's for a 4x5 room

hps sorry

i just swapped a 2 1/2 week old plant from soil into hydro, and it is rockin
