Big CFL's

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.
 
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?
 
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.
 
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.
