Lol I think my way is probably too ghetto for some peeps liking but stick the clone in a rapid rooter,put a sandwich or nappy bag over it then mist once a day,two weeks later when the roots are sticking through,pop it in your medium.
Saying that,Ive been meaning to make a bubble cloner,it would be nice to be able to check the actual stock now and then,but with the method Im using just now Ive never lost a clone so I suppose if its not broke and all that...
Sorry thats me gibbering again-what were you propagating the clones in in the first place,were they put straight into coco?I do think rapid rooters are the way to go,you want whatever you put them in to fit snuggly around the stalk.Also you know a fresh rr plug will be clean and sterile
