Yeah I think knix put it better than I did...they seem to like a rest from light - mine always look better and more vigorous for a few hours darkness. There are plant processes that can only happen in the dark, and if they are allowed to carry out these processes then the plants seem happy for that.
How funny, was planning exactly the experiment Knix mentioned...maybe for 4th grow...take clones from one plant, get another hps light and grow them in similar but seperate areas with one at 20/4 and one at 24/0...but til then, tis all potatoes ans carrots, whatever you prefer is fine....unless you prefer to tell me what I may or may not say, then grrrrrr.....
Have a happy day peeps, yaha tis friday...
