cfl questions

[propain]

if i have seedlings that are only a few days old will it hurt them to have alot of light bc i have 4 42w cfls on each and they are 3 to 4 in away and they are starting to turn yellow and look like they are about to die

That's probably a heat issue not lighting. Do you have ventilation across the plants.

why don't you move the lights away and see if it makes a difference...

i had to drop down to 27wat cfl to get back into the light spectrum for veg the 30watt was a soft white (red)the daylight is in the blue spectrum

Are you adding any nutrients? If so you might wanna back off for a week or so because you might have nute burns on your plants not to mention you might be overwatering...hard to tell without a pic

How many seedlings? You need only about 25(veg)-50(flower) CFL-watts/square foot. So your bulbs are over-kill unless you have like 6 sq feet of sprouts.

I agree.

You only need exhaust fans.... at least use the bigger one to exhaust out of the top.
