Just one plant in a 1ftx2ft space as tall as 6 ft but trying to keep it short as 3ft. Also i cant find 42watt cfls at a hardware store most is 27w..Cheapest way to go will probably be some compact fluorescent bulbs. With $100 you can get yourself a nice 150w hps or something like it to fit your needs. How big is your grow?
If you have a hydro shop around you then you will be able to find everything you need, and you can at least get some decent cfl's at a hardware store.
both and spread them out to better illuminate the plantwhat? 2x 27w 6500k or 4x 27w 2700k?
also keep your lights about 2-3" away from canopy of plant.both and spread them out to better illuminate the plant
reason of using different colored lights is you get a wider spectra. also 6500k - better VEG 2700k - better bloom
