Ive pre-soaked rockwool with pH adjusted water and 1/2 strength grow nutrient overnight. Our water is very alkaline like rockwool, used a pH downer.
Worked a treat.
others may have different methods?
Imotep Reviewed by Imotep on . Stabilizing Rockwool I have heard you guys talk about curing your rockwool before use. I would like to know how that is done,the easiest method. I also would like to know were you can purchase the gel that you put on clones to help stimulate root growth. Thanks Bizzy Rating: 5
