    Default 125 watt Cfls heat vs smaller bulbs

    Hi peps ive got a 50x50x100 cm grow box and 125 watt cfl and 6inch fan my temps are getting as high as 41c i was using my 125 watt cfl with a refector and since ive taken the refector off the temps have droped im guessing because of the confined space but therer still hitting top end of the 30s i was just wondering if i switched to more smaller bulbs rather than 1 125 watt bulb will they give off less heat

    Morning butterbean. I'm in a similar space. 60x60x140. But with a 4" rhino fan and scorpion filter. I've taken my reflector off for the same reason and have the bulb hung vertical. Temp sits at 27/28c with the fan on the first setting.
    We'res the tent at? Bedroom,attic?
    What sort of bulbs were you thinking of? I've seen on the net people using 4 or 5 of the Philips 8w led bulbs.
    What's in the tent?

    I think your going to generate just as much heat with multiple bulbs. Look at upgrading the extraction rather than changing the light.

    Ps, ive moved this over to the novice section to keep the sponsors section tidy
