Taking in oxygen and giving off CO2 ?????????
grey1223 Reviewed by grey1223 on . which is better? 24/0 or 18/6 lights which is better? 24/0 or 18/6? I've heard root growth is better on 18/6, but 24/0 seems to make more since. I was wondering if anyone had experience/knowlege on this subject? Rating: 5
