I'd highly recommend Aero cloners. I built my own and they worked so well, I can give you a parts list and how to build it. I'd lose a few over time but had at least 90% or more take root. Cut stems under water and then into cloner, that was it. I would only scrub the tote and never bleached the pump ever, never had a problem. I never used a bubble cloner until I moved, but I figured I'd give it a shot, and bam, 100% success in 6 days. Then cloned some more in 10 days. Now it's been 3 weeks and some things terribly wrong. I'm on the verge of building another Aero cloner, but the root plugs sound even better because now I only take about 10 at a time. If the plugs can get roots in week I'm sold! Is there any tips for the plugs?
