Big CFL's

How close should the higher watt CFL's be to the plant?

how big of a space and how many?...even though they don't produce alot of heat..in a small enough space they will

its on a shelf under a desk. Heat wont be a problem but the CFL is about 8in away is that ok? its one of the bigger wattage ones.

put it like 2 or 3 inches away...is it just one plant?..and also, what is the light spectrum of the bulb?

there is 2 plants and i think it puts off like 2700 lumens

are you sure it's not 2700K?...did you find that on the bulb?

pretty sure it said 2700 lumens. y whats 2700k?

2700k is a Kelvin (color temperature) of the bulb, if it is a 23-26 watt bulb it puts out prolly 1600-1800 lumens.

i just got 2 big cfl's this is my first grow and i put them 1-4 inches away from my two plants with a tiny tiny fan blowing so there is a bit of movement on the tops or ur plants every since i dropped them down to about 3 inches i can see my plant just soaking it up and loving it. you will see dramatic changes if you put them 1 - 4 inches away. just dont make ur cfl's touch anything and u should be good

yeah the 2700k is more of a red color....you want more of a blue color at first like 6500k..i made the mistake of using the 2700k's at first, and they really didn't do much..how many watts is your cfl?

it is a 26w

ya how many watts is your CFL, (REAL WATTS) not equivalent.

if it's like 40-80w you might want to move it like 4" or so, if you don't have a thermometer you should get one. one of those indoor/outdoor ones are good because you can put the wire for the outdoor under the lights to see what the direct light heat is that your plants are feeling, then you can mount the device in the box and see the ambient temperature.

those 26w you can put like 2" over the plant and be fine

You said you were using one of the higher watt CFL's right?
What is this 26watt stuff about?

if your hand cant stand the heat neither can your hand you dont need a thermometer for a cfl i can hold it in my hand all day 3 inches.

He meant neither can your plant, not hand. This is a good rule of thumb

yeah my bad.. i am obviously way to stoned to even think about typing....
