Never got into cloneing with peat pucks or rockwool yet but have stuck to a method I find is great!

I use a soil mix with perlite,more on the perlite side though,now of course you can root your clones just in perlite but what I like to do is use a bit of soil as well, mixed in with the perlite,that way my medium stays wet a little longer and less chance of drying out!,and when the cuttings root they have a little soil to eat from! I also find a little soil mixed in helps keep the cutting tightly into the medium,perlite on it's own stands a little loose,the water I use on the soil/perlite mix,is ph balanced.now it takes me about 6 to 7 days to get the cuttings to root and at 10 days I am ready to take cuttings from plastic containers to a planting pot...I use dome covered mediums,and a spray bottle to keep things moist,I also use a few flourecent lights directly under the clone trays,to keep the tempature up in the dome covered medium,if you don't warm the bottom of the clone tray and keep the clones above room tempature it will take alot longer to get the cuttings to root!,and if the trays are to cold underneath the cuttings may get a mold problem before ever rooting,keep the under side of the clones warm I can't stress that enough,you can lay the clone tray right on top of the lights if you want.when I first started clong it was a ruff start I did everything right but failed to keep the clones warm exspecially the underside,and failed many attempt's,but since I lay them on a doubled flourecent tube light it has been perfect,roots are kept nice and warm and grow crazy!...........
