Little plant big pot ! I'm curious how many other homies on WP do this ? I can somewhat understand if you're growin an awful flowering plant, but that's it. For every one reason you can give me for this setup, I can give you 10 reasons why not to do this ! More perlite too. I've never grown in pure coco. GL and I hope she's a monster !!!
I use solo cups for coco and once I see roots coming out the bottom slits and then its time to replant in the final vessel unless its a DWC or RDWC and I keep those in rock wool until they have a lot of roots coming out the bottom
