Righteousness, the input is appreciated. I do the same type of research, I shall try it if I can find what I want the bulb I would like to use. I wouldn't assume to try using the uvb until then 2-3 weeks or perhaps an experiment at the split of the stock the last 10 days of her life ...we shall see.ive had great results in splitting stocks in comparison with the same genetics without splitting them. Big push at the end 2 days of darkness and no waterings for 12-14 days at harvest.jimmi2scoops wrote:Theirs no need for uvb until last 2 or 3 weeks of bloom used for 10 to 12 hours daily. From what ive read and watched on youtube, they say tests were same and their was no added benefit running them all way through bloom or last few weeks of bloom. I started using them last 2 or 3 weeks no myself for ten hours daily doing this gives mer chance to get in room to do stuff as well. Hung around 12inches from canopy, make sure you save buddage from that area cus the uvb soon becomes defunk further away from buddage it gets. You may notice longer taller trichs on those closest uvb.
Maybe raise the light for a week or so till roots become established young seedling are easily fried under powerfull lighting.
Good luck with your grow.
