What's the temp in the room. If it is to cold it could take forever to root.
make a bubble cloner. Works way better. Easy peasy.
we need WAY more info to help you at all. Do you make sure the bottom of the cut goes to the bottom of the rooter? Do you have water at the bottom of the dome? Do you mist? How much leaf do you leave? Do you pH your water and if so what is it? Do you make sure to cut the base LAST? etc. etc.
Cut the base last thanks for that tip.
I dont know why people say this...
I very much prefer rockwool to anything an ive tried it all.
I don't know why you prefer rockwool. Bubbler has got to be the cheapest easiest method of them all.
No buying medium, no clone gel, no dome. Just cut it, stick it in the puck, and wait... for less time than rockwool or any other dry method.
