I have an Aero cloner that I made. Some strains root faster. I don't use it anymore, I went back to the basics. It's been better for me.
Bought an Ebb and Gro. Ditched it and went to hand watering in coco.
Aero cloner. Ditched it, went with rockwool and a heat mat.
PH meter, ditched it and went with the GH drops. For $10 a bottle, it will last me two years. I got tired of replacing probes.
4x4 flood and drain tables with hydroton. I ditched it and went with coco.
I try and stay away from anything with a cord or pump. The simpler the better for me.
This year I'm putting my ballasts in my room and boxing them up, I'm trading them for the sun and unlimited space.
