you dont need a dome almost with anything weed related.
It helps with media based clones more so then water culture.
Ive done aero and bubble in one firm or another for probably 12 plus years.
I also can get 100% with rapid rooters and rockwool.
But my aero is fastest followed by bubble followed br rockwool.
My fastest ever roots where 5 days from cut
And they where roots not bumps.
I have never had them root faster any other way.
Now that being said if you do awsome in rockwool
Why would you want to try an aero or bubbler set up?
I would choose the best method that works in my situation
