anyone that want to use t5 take a look

Roy, T5's dont factor watts per gallon like MH and VHO's do.

Its this complicated PAR value. It gets more complicated when you factor the ballas you are using (i.e. Ice Cap vs Workhorse, etc).

Dont' worry, those tanks might only be 4 wpg, but they put out an amazing amount of light!
