since i keep my plants so small the hps does very good at gettin light to the lower parts of the plants. i do plan to start growin larger plant and im gonna use a few cfls around the center if needed. i think im gonna add a couple more of these 150 hps. i'd like to have 1 per sq ft, and at $20 each it should be easy to do.. i love these lights. cheap and effective.
i do have to find a good space heater for my buildin. this morning my temp was 43 F way to low.. so if anyone knows of a small space heater that is safe to leave unattended and don't pull tons of power let me know.. thanks
