So I got a Black Widow clone & a Blue Sky (local breed) clone and they were big enough to take cuttings from. I had to take multiple cuttings from a single branch because the donors weren't that big. I have 2 20 gallon grow sites and a 20 gallon res. connected with 3" PVC, a via aqua pump (560gph) and a 35W air pump. It has proved to be very easy to manage nutrient levels & PH as the pump exchanges the volume ~ 20 times/hr. The clones have been in the system for about 2.5 weeks now. I ended up with 5 of the Black Widow which were cloned in rapid rooters & 1 of the Blue Sky which were done in rockwool. The larger ones in the pics rooted faster. I think I'm gonna let the screen fill in a bit more before i flip 'em.
