For staring clones and seeds use rapid rooters or peat pellets. They can be washed off or just put right in hydrotron. Better than rockwool.
LOC NAR on probation Reviewed by LOC NAR on probation on . Substitute for rockwool? is there a substitute I can use instead of rockwool? I could'nt find a thread asking this question lol, or do i really need it? If i seedling it in a soil pot so it grows some roots can I transplant it right into the hydroton? Rating: 5
