Constraints with lighting require additional research. I could not justify the additional costs associated with
hps. I could make it work with H.O. T5, but I lose the edge.
Note this is for my situation and constraints. I grow lettuce, greens, and some basil/cilantro as well as all my outdoor garden springtime "starts". With T8 light fixtures, I get the right amount of light without having to add additional cooling, dehumidifiers, red spectrum
lights etc. It works well for me at about $6 electrical cost per month per 6 light system.
It took alot of research, number crunching, and stubby pencils to determine that flowering plants were out of reach for my basement grow.
I will have a hoop-house / greenhouse in the future to allow the flowering plants to align with my cost threashlds.
Best of luck with your grow rooms. Post some pics when you can.
