the two that are growing did germinate in rockwool (I had pretreated it before too). The white cubes that you see ARE NOT ROCKWOOL. They are some new grow cube product the shop i went to got. They are ph neutral and apparently they are great for germination.
k1ng87 Reviewed by k1ng87 on . first aero setup I just threw together an aeroponics system on a very low budget. Its day 20 from the day i planted the seed into the rockwool to germinate. I've only gotten two to germinate so far but the seeds I have dont seem to be that good. Rating: 5
