Newbie question re lights for seed starting
I'm a regular on several other forums but just found yours, and there seem to be alot of experts here! Hope you can help me. I'm planning to use a downstairs room that stays consistently dark and cool to start perennial seeds in January, to set out in my garden in the spring. We live on a mountain at 3300-foot elevation, so I'll be trying to get a headstart on the season.
Anyway, I have a large homemade light box that was used to 'expose' materials painted with photographic emulsions (an oldfashioned printmaking technique). I'm wondering if this setup can be used to germinate seeds. It has 6 ballasts fitted with a total of 11 light tubes (one broke). Each tube measures about 22" long and is marked
GE 20W Black Light F20T12-BL
Will these lights give the correct spectrum that the seeds need? If so, how close should it be suspended above the flats? If not, what should I replace them with?
Thanks very much in advance for enlightening this newbie!
