im having a lil trouble rooting my clones im using a 400W mh but its just to much light. I hear that clones need warmth and not much light to root. Now im wondering would a t-5 bulb be better than a t-12 for rooting or would there be no difference?? just to root nothin else because after they root back under the mh. i alrdy have a t-12 ballast but buddy broke the bulbs accidently :S. im gonna use the t-12 for the time being but really just lookin for some opinions if its really worth upgradeing and if its so much better about how many days would it save me more than a t-12? thanks.
