Well shit. The breaker can't handle adding a 1000 watt HPS, so I'm gonna have to flower under the current lighting.
Fortunately I got my temps dialed pretty well, so the glass on the reflector is about 6 inches from foliage without a problem.
I will see how it goes with 6 plants for now (~100 watts per plant) but depending on the stretch I might have to put one or two of the girls outside in a cold frame.
Today is technically the first day of flowering but it will take a little while for them to really switch over.
Let the fun begin
