Yeah that would work great you can 2 in the regular eb but three I'm sure is crowded. Have seen you the roots I had in jr's they filled the entire pot and Rez. They go crazy when you put them on a Rez it's pretty cool to see how fast the roots will eat up the topdressing
Yeah BAS seems to have quality control down for that i'v seen no personal experience. You know how that can go maybe now that they are getting bigger the QC might go down. But it looks like they use top quality stuff in there soil worth saves and recycling
That has been a concern of mine as well for one grow it would be fine but If I do that I want to fill and go no till for multiple grows with out moving it. I wonder what the pot wicking system would look like after multiple grows no till
