    will low temps slow the growth of buds? the temps are at about 62-65 and the buds seem to be slowly creeping along after 4 weeks..

    Yes, temps too cold will slow the growth considerably. You want it to be closer to 75F.:leaf:

    Is that day or night temp?

    65 degrees at night is probably fine.

    UncleBen has a post on garden tips and tweaks that says night temp should be 15 degrees lower. He uses 85/70, but 85 F seems hotter than others recommend; whether you are running CO2 probably has quite a bit to do with the optimum temp. They can handle higher temps with c02 enrichment.

    I am shooting for 77-78 F lights on and 63 at night right now myself. (no Co2)

    Its usually week 5 and later when buds start to fatten,
