There's been lots of discussion of lights and lots of opinions. I will say one thing for certain, you will most probably not find what you are looking for at Home Depot unless you can live with a 4-tube t8 florescent shop light. That's the best they have to offer. Try shopping here
2 to 200 Watt Compact Fluorescent Bulbs : 1000Bulbs.com The Light Bulb Superstore. I use both the 55 watt models and the 105 watt model all in "full spectrum". I also use a fixture with 4ea 48" t5 florescent tubes over my orchidarium. Here is my upstairs grow area with lights on
and the orchidarium with t5 setup
Now I know many members here grow under less hi-tech lights, but I have tried and rejected lots of types of lights over the years as having faults I couldn't live with. Just my two cents.
