hey i just started growing about 10 germinated plants.. They are under a 120 watt plant light and they all seem to be doing pretty good. they are in seed trays and seem to be liking it. there is a fan on them and they are in an enclosed space with all white walls. anything i should know? i dont think that the light im using is probabaly good for a serious grower but the whole setup was 14 dollars at home depot haha. tell me what you think, and what i should keep in mind.
