I have cloned about every way you can and the best for me is areo cloners. No rockwool or starter cubes.
they can cost alot and can be built for very little. So if money is no problem, go for it.

Cloning, what can I say ? If I could never go back to seed I would. But it's the only way for me to get something dif.
The time saved is well worth it and alot faster getting the next round veggin for the flower room.
