Yep, that's what I'd do, and have done it before, just double up the dark period once to get them on the schedule you want. Didn't cause any probs. Wouldn't make a habit of it or anything (hermies possible if you do), but once, they don't seem to mind.
jamstigator Reviewed by jamstigator on . Switching 12/12 time Without getting into why (very long story), i need to change one plant light schedual completly. The light comes on at 8PM and goes off at 8AM right now. What I need it to do is go off at 8PM and come on at 8AM. What is the best way to do this without stressing out the plant to much?? Rating: 5
