I am almost finished my first round of Hempy's.
I did a 60 / 40 Coco to perlite mix.
Havent experimented at all, just read somewhere that it was a good ratio.
Havent experinence any issues other than those of my own creation.
I flowered them at about 1.4M so there HUGE untendered shabby looking plants.
I will keep them allot smaller next round.
I like the easy-to-use set up of Hempys.
Great for LAZY people like ME!
Hope you get some figures in, in the next week or so.......
I might have to adjust the ratio on my next set, to the most voted..
