I am using an HLG 100 in a micro grow setup! This is my second grow to date. First go around was a bag seed from a friend. I learned a lot for that, upgraded some items in the garden( light mainly), and got some real beans! Exited to try out some sweet genetics!!
You selected a good light. May I recommend you up your humidity to 60 + RH. You will obtain much faster growth and efficiencies of your nutrients and lights. It's called a VDP chart you can look it up. I'd love to explain but you'll get a better understanding if you research it yourself. Cheers and good luck with your grow!
@GreenHouseLab, awesome thank you! I am actually a few weeks ahead of this ATM ( updating the rest after work) , but my humidity hasn't changed... I have heard a little about vpd lately, and will be diving into it now!
Come check back in a few hours... Should be updated!
