growing with little light
I've grown with fluoro tubes, it can be done ... if your 'purple' light is like a 'Day-Glo' type, ditch it immediately ... ultraviolet light won't work at all ... the cheapest lamps to use, are at your WalMart, etc... use the 'Daylight' type for vegetation (blue wavelength) ... use the 'Kitchen and Bath' type, for flowering (red wavelength) ... keep the tubes an inch above the plant tips ... fluoros don't penetrate ... keep an oscillating fan going ... good growing ! :thumbsup: ... your yield will be small, but the experience you gain will be BIG ... I worked my way up to sixteen 48" tubes, before switching to high-pressure lamps, the difference was amazing :smokin:
growing with little light
I definitely agree with the post about CFL's and the fact that they should be close but I think you can grow at least the first few weeks with the purple grow lights. I have a plant that is just breaking the surface with only two purple grow lights. They say they are grow lights so I assume those are the correct ones, not the ones to ditch? Anyway in your case put the purple lights basically right on the plants because from my experience they do not get hot barely at all. Good Luck, hit us with some pictures soon:rasta:
