I would go 24hrs until you can get some more lights on them. Get more lights asap, it's important or else you'll end up with small plants and small yields. Check out my grow log....hipro's first grow log.....and you can compare the difference between our plants. (Mine's 21 days old today)
HiProGlow Reviewed by HiProGlow on . First Real Grow So I bought 5 Grapefruit x Nevilles Haze seeds from Female Seed co a few month ago and I decided to grow two at my friends house with him. We have them in a closet under a single flourescent light. The plants are at 3 weeks now and they are 4 inches tall. I have kept them under 18 hours light for the past 2 weeks before that it was 24 hours light. The pictures are at 3 weeks into veg, I plan to grow them to 3 feet or so, since this strain is supposed to streach a lot durring flowering I Rating: 5
