Why would it make any difference with regard to total heat production if he uses 1000W MH versus 1000W of HPS? Sure, HPS puts out a little bit more light on the red end of the spectrum, but I don't believe that MH is that much more efficient that fishhunt is going to be able to just leave the girls under the MH and not experience heat issues.
Obviously, that's just my opinion.
hey im just wondering if i can veg my plants in flower room under 1000 hps for 12 hours and then move them to a t5 for the last 6...reason for doing this is my winter veg spot gets to hot in the summer and with all the a/c going and what not i cant efford to cool the area...i have 2 vert 1000 hps, co2 and all that i flower room so im just worried the change from hps to clfs wil harm them......thanks for the help.
I don't think so. Once they're acclimated to the HPS they'll be alright, they won't 'de-acclimate' just because they're going back and forth daily. Put them on wheels if you can, that's my suggestion to save your back.
