Compact Fluorescent Light Discussion

[Chronisseur]

Hey Steve, (or anyone who knows), How much cooler do the 'cool white' bulbs actually burn, as opposed to, say a daylight bulb? Is there a significant temp decrease?

There's a definite difference. A lot depends on if it's a closet grow or a grow cab. A couple of years ago I had a small grow cab (12" x 24" x 42") and I did all CFL--I had 4 x 26w on the canopy, and 2 x 26w hanging down a little lower. I remember the temp difference was about 3 or 4 degrees during flowering, even with the fan on. So if you're average is in the low 80s during veg, you might be getting into a bad area during flowering unless you increase your ventilation.

Closet are so great because you've got added area for heat dissipation. If you're in a closet, having the door open for a while each day will make up most if not all the temp difference.

i have 4 65w cfl's in this locker in my basement...I had them on for about 30 mins while i was workin on tha locker and the base of the bulb was getting really hot. Is that normal?????should i run 4???? get back at me. peace.

its an old post, but a good point.

FYI: in a cfl, the glass tube/spiral part will usually be only warm to the touch, with little heat. however, since they have built in ballasts, the base of it can get quite warm verging on hot.

hey bobbong if you are still around can you please tell me the exact lights you bought from canadian tire and the exact soil you used because my plant at 1.5 months looks like yours did at 17 days and mine is under 150 watt hps so you are a huge inspiration to me and i want to do everything exactly as you do

Not much difference at all.
The actual temperature has almost nothing to do with the color temperature of the bulb.
A 40 watt daylight bulb will burn at approximately the same actual temperature as a 40 watt warm white.

Hey im currently using 3 32w cfl spiral bulbs that say they preform like 150w do you think that they will be enough for four plants?? should i just get more of the same or add a HPS or HID to the mix?????

#1- 64 watts of cfl will cover an area less than 1 foot by 1 foot.
#2 - HPS IS HID

Just stopping by to reminisce in my first grow log.

I miss these days.. but i've learned so much from it too.

This thread and all these pictures are simply proof that anyone can do it... and that it's really not that hard.

Put your mind to it, become one with the plant.. and learn as you go.

Cheers,
Bob.:rastasmoke:
