I've been searching this site but have come up empty handed. I'm curious if anyone has any experience with the activator pots (?) I'm just looking for pros and cons, and your own experiences. I see the one that big brain sells ( i think arounnd 2000$) and I once saw a post on FB that another company made something similar to it, or maybe it was home made. I'm not sure. Just curious if whatever benefits there are will justify the cost of another tool. As always, thanks in advance. You hydro folks are always quite helpful.
