I always run veg at 24/7 ...... never had a problem with it . the only time they see dark is if the power goes out lol
they grow very fast with 24/0 lighting. with excellent root growth.
i've never gotten FIM to work for me .....
i had a hard time with the FIM untill I read somewhere that you should only leave the last 20% of a shoot on the plant, when the new shoots swell into a ball shape just before the leaves unfold, you pinch or snip the top 5% off of the ball shape and all the leaf material above that and it works take more and you have just topped less and it dosent work at all... I hope this is a good description.... The newly developed leaves sorta ball up at the bottom of the new shootsi've never gotten FIM to work for me .....
whats with the cup shaped cut i've read about when fimming ???
