right now i have 2 400 hps in a homemade air cooled fixture, do you think it would be better to split up the lights and put 1 400 above weeks 0-4 and put a 1000 hps above weeks 4-8 I can do this but it will be some more work or do you think it will work to just switch out the 2 400's and replace with the 1000 and be ok, I just want to do it right. Thank you all your input is just what I need!
