Or was that 4-20?

If it is true that roots develop better in the dark, then cloning is best done with SOME dark period. However for full on VEG growth I agree that 24 would be best. I don't need things to grow any faster then they are already.:thumbsup:
mendokid Reviewed by mendokid 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
