Rooting Mediums
Set cut stems in rockwool, Jiffy (peat), Oasis root cubes, or fine soilless mix. All cubes are convenient and easy to transplant. Some growers report rockwool cubes stay too wet to make clones. Other growers love them. You can also use small containers or nursery flats full of coarse washed sand, fine vermiculite, soilless mix, or, if nothing else is available, fine potting soil.
Fill rockwool tray with water, pH 5-6.
The growing medium must drain very well to withstand heavy leaching without becoming waterlogged.
