I'm interested! I just never heard about it anywhere. How much water is needed to be in the tub to properly root the clones? Also I've always wondered how people do the transfers from a mediumless clone to hydroton or w/e medium you use. It's jsut a confusing subject for me. Also, would the constant moist environment not be optimal growing conditions for mold and algae and all that bad stuff? Please I'd love to know more. Pros and Cons? Thanks in advance.
