Those hempy buckets sure are treating you alright! Your Mi5's got me to try them, you just might have sold me on this hempy style. Really curious to see how it does outdoors in your greenhouse. Fingers crossed that it works out for you.
Do you think you could "wash" the perlite in between grows so you wouldn't have to throw it out?
