Compact Fluorescent Light Discussion

[Chronisseur]

i am trying a grow with 2-200 watt compact fluro's 36000 total lumens for 4 sq. ft. will post pics soon. i saw a website from uk that has hoods for sale that take 4 and 6 large cfls 125-300 watt ones, the 6 bulb one is approx a sq meter. they have 150 watt bulbs rated at 18,000 lumens also(mine 18000 l for 200 watts). so that 6 bulb hood would be 900 watts and produce 108,000 lumens(approx 12000 lumens per sq here), heat would no longer be an issue in this grow. what you guys think?

Sounds good! I would reccomend leaving room for an extra bulb or two come flower.

2700K = warm white, (more red) use in flower cycle.
6400k = daylight, (more blue) use in veg and flower cycle.

i got 2 42w and 8 26w, is 290 total watt powered cfl's enough for 3 plants during flowering???, the way i got them is 5 shoplight lamps with y sockets on all of them , three are hanging directly on top of each plants and two are clamped on the rim of the pots so it can hit the bottom, should i move the bottom ones to the top or is my setup ok???

You should be good to go.
Don't expect huge yield, but you should be able to grow something worth smoking with that.:thumbsup:

great thankx man, loving this forum very very good info, currently got one in rollitup.org oh yea one more ? should i move the lights that are postion at the bottom to the top??

If your plants are taller than 16 inches, leave a couple of them low. If they are under 16 inches (and they should be if you're using all CFL's), all light from above should get light to all parts of the plant..
Of course, if you plan to scrog (recommended), then all lights should be above the screen.
