hey hydro, forwhat has given you good info.

1) i'd say no, with a bubble cloner, you don't really need a dome

2) with a bubble cloner, you should have enough roots to transplant within 10 days

3) easy as shit, as forwhat said, once rooted, any female cutting can become a momma

4) with topping and careful pruning you can grow any female cutting into a bonsai momma that will produce hundreds of clones per year
