I have never had any kind of success cloning in rockwool. I hate that stuff anyway. I have had close to 100% in both my cheapo areocloner, and in soil. Search the cloner if your interested in building a simple fantastic device. If putting in soil, it's real easy; Just flood the non fertilized soil once before planting the clone with water and a couple drops of B1 like SuperThrive PH'd to 6.8, scarify the clone, dip it rooting hormone, poke a hole in the soil and plant the thing. Keep it and the soil warm and moist however you want, and it will root within a couple weeks, providing you cut the clone from a good area of the mother. Use a humidity dome or mist or use anti-wilt. Harden after they get about 3 inches of good root.

Cloning problems I tried to clone a plant last year during my last grow and i took 6 clones.The problem is I couldnt get it to work and I tried like 4 times.I would cut the clone at an angle neer a node when the plant was in veg,then i would dip the cutting into rootech gel and the i would put the cutting into a rockwool cube(yes i soaked the cube first to remove its acidity),then i would put the cutting under light,and then water it but not to much or to little.But they always just fall over and die within a Rating: 5
