Yea, seems like a idea way of seeding various strains in a controlled fashion. These are my starter prospects, I've got a few hundred more coming in behind, so I might try some of those as well. But my guess, is that if you've got the technique down well, most of this is going to be strain specific, some doing better than others. Currently, they are all still in shot glass size cups, but I'll transfer a few, once the balls dense up some more. I've been taking out a bit of coco, then adding some in the bottom, so the roots can grow into it again.... do it in layers, then when I transfer to the solo cups, I'll plant it shallow, and do the same thing....
Then maybe I can remove tiny bits of the media as time goes on, and fill in all the voids.
