Don't have any names memorized, but I've done quite a lot of reading up on the general subject, I seem to remember Ed of High Times amongst others, if you want a name. But from the literature I've read, the conclusion seemed pretty unanimous.

faithless Reviewed by faithless on . Why 18 hours works for me O.K here are a few reasons to run your veg 18 hours instead of 24. 1. You can run 25% more wattage for the same money. (so a 250w on 24 will cost close to a 400 on 18). 2. In a sog or perp harvest where your veg is running constantly 24 or 18 will have no effect on yield though it will have a large impact on electricity consumption. 3. It is simply more natural for the plant. To be fair I will say that if you have to run the same light for veg and flower 24 may speed Rating: 5
