Re: do it yourself 'grow' lights

Cool and warm was the other guy. I use all "cool white" tubes with very good results. (I've found that its the lumens--brightness--that counts more than wavelength.)
Old florescent tubes (like some colors of neon) contain a fair amount of mercury. Newer ones--designated by green-colored pin ends--have little or none. Much like alkaline batteries...

Oh, and you should buy fresh tubes for seed-starting every year; they may look the same to you, but the plants can tell the diff. Use the old ones for regular lighting.

I've always just used the tubes that came with the fixtures, could you explain why one cool and one warm? And do they all have mercury in them? Thanks.

H M is absolutely right. There's also the still cheap, high end version that I use--4 ft fixtures what got 4 tubes each. They're awesome! And the new T-8 tubes are sleeker, use less juice and got (less?) (no??) mercury in em.

I have used shop lights (4 foot) with one "cool" and one "warm" tube in
each rigged with cord on a pulley system for raising and lowering the
lights to accommodate the increasing heights of seedlings. This system is
inexpensive and effective, especially when plugged into a timer for
automatic operation.

anyone have simple designs for inexpensive 'grow' lights; not for
hydroponics; for seed starting. something simple for use in a classroom
on top of a
table.
thanks!
