Sweet. I’m in raised beds and fabric pots.

My indoor flower room has 2- 2’x4’ fabric beds. Finished my soil this weekend.


Very nice

Cool. I’ve got DJ short BB seeds dying to jump into a glass of water.

Just added Mataro Blue from Kannabia to the grow. Really looking forward to see how this one turns out.
