Hey Blitz. I just started 2 clones in hempy cups and my last grow was 7 C99 in the hempy cups, so hopfully I can help. first off, I usually keep a humidity dome on them once they go into the cups only for a few days slowly taking it off a little more every day. second, LST is not a prob in hempy, though i would start it at about 4-5 node. just bend it as far as you can without pulling it out and tie it down. leave it for a few days then you can retie it a little more if you need to. once your roots take hold in the perlite you will not have any probs. Now to the important part. when feeding, first off make sure you are using half strength nutes from what the bottle tells you to. my feed schedule is usually on a 2 day cycle where i Feed on day one, wait day 2, pure water on day 3 then wait again day 4. then start the cycle over again. Does that make sense? On my first hempy setup it got real ugly twords the end and i figured out that the salt buildup in the bottom of the cup was crazy!!! It's a lot harder to flush that stuff out in hempy, at least it was for me. Make sure you Flush really well about once every other week or this wil happen to you as well. Also, I've got no problem helping noobs around here. I believe that is what this site is for, helping each other out. Any questions you may have durring your grow feel free to PM me or post and I wil do my best to help you out. Good luck and happy growing!!!
