Just a follow up I cleaned the plants and the system out. Changed the water to distilled. Bought the clonex but have not used it.
The stems are still clean after a few days

Thanks
markhug Reviewed by markhug on . Cloning question I have started some clones in a oxyclone 20 site using well water and one quarter teaspoon of Superthrive. After 3 days they have developed a film in the stem that is sitting in the water. Is this a normal condition. My leaves are also starting to yellow. If not what can I do correct the problem. Rating: 5
