I want to be clear on this. I run 18 because I believe you get twice the space for the power you use. My point is misunderstood. If my plants grew 25% faster that would only save me 1 row of 5 quart cups. Perpetual harvesting is my chosen method and I think mine is pretty well tuned.
thcreactor Reviewed by thcreactor 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
