if you can master cubes I say you are better off. Unless you are aero growing then it might not matter so much. You see the rw cubes keep the roots protected. Then when i transprot them into the bigger system i can avoid root damage and transplant shock, which i have had before and hermied a clone. It looks bad when they stunt from root damage.
I am using the complete heat mat, clone tray, rw cube insert, humid dome, and h202 set up for clones. I am about to cut tonight. I have used dwc cloner i made with a coffe can and an airstone with 100 success. Aero cloning and dwc cloning is easy. But what kinda media are you going to put them into next? I did not see that.
Also you can make one of those cloners for CHEAP! It si just a water pump and a sprinkler head. that's it. Water pumos are like 30 for a good one and sprinklers are like 6 bucks at home depot. No tough sceince at all. Stinkbud has an excellent cloner to build with complete plans. His is huge bud you owuld get the idea.
Dwc is easy. Just drill holes in a rubber,aid. Drop an airstone in the water and let the clones hang. Drill 1 inch holes so you can pull the roots out without damage.
If you learn rw then you are set i beleive.
