I have built an aeroponic system and am ready to start growing. I have a question on how to start my seeds for a areoponic system. I will need to put these in 3" baskets. I don't really want to start them in rockwool because I am afraid I won't be able to seperate the root from the rockwool. If I put the rockwool cube in the 3" basket , I'm afraid it may give the plants root rot. Any ideas that are proven?
