Im not trying to argue with anyone on this topic, but i had my lights run 24/0 for a month now and just now started a 20/0 period.. and from my experience the plant seems to pick up alot of growth in its short dark period.. i dont want to get technical with all of you its just something i noticed, more like a break than rest and whether its been tested time in an time out you just never know how each individual will react to a little darkness, mine seem to pick up growth with 4 hours of dark and kinda gets them ready for the next 20 hours of light..
gmoney5ss Reviewed by gmoney5ss 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
