Last time i tried to put rooted clones from a cloner into rock wool, it didn't work out to well. Can i just go from the cloner right into hydroton for ebb n' flow without the rock wool?
sure you can i did it last year, i used RAPID ROOTER GROW PLUGS and rockwool the ones that were in the plugs were ready to transplant into my hydro sytem about 5 days faster. they are cheap , work great and dont raise your ph like rockwool can here is a link to those plugs Rapid Rooter Grow Plugs - 50 Bag
But what happens to all the roots hanging through the small net pots (if you're using those)? I always wonder this when I see people starting clones in those small systems and then moving to a large one.
