What kind of heat from the light alone could I expect to see in a 2.5 W x 3 L x 7 H ft chilly groom? I understand it's like showing a seedling and asking for a yield prediction but just some idea of what your temps are like off hps could give me an idea which is more than I have now
How powerful of a bulb will I need for 4 autos? Was looking at 600w with a lummi black digital ballast and sunmaster dual spec bulb has been mentioned a cple times.
Is a parobolic reflector the best option if I don't need a cooltube to keep heat down?
It's hps or using the 1x 300w blue, red and dual bulbs plus a 125w dual spec on a homemade chandelier, so 4 multi directional cfl bulbs in total
Also as I'm using a 150 IS board for photos I suppose I better factor electricity in
I'm sure all this has been discussed somehwere, it's hard to find specific answers sometimes and opinions always change. Just trying to get ready for the next run with a more permanent setup
