About the power.... I looked at my breakers again. All breakers in my house are at least a 20a (the number 20 and up written on ALL breakers in my breaker box) so I'm assuming 20a and NOT 15a, correct?? If this is not the case, I will just install 2 more 20a breakers(have iigher amp breakers installed they make 30/40/50) and run new wiring to a receptacle in the room wiring is already in place...
So, assuming 20a breakers ... that would be: 1.5a (450cfm fan) + 4a (400w ballast) + 9a (1000w HPS) OR 5a (600w HPS) + 6.8a (dehumidifier) + T5's + miscellaneous = hmm about 20a it looks like. I guess either way no matter what light I use, need to install more 20a breakers...?
