i baught the pack of rockwool cubes from the hydroponic shop and the guy told me to soak the cubes for a couple hours with 5.5-6 ph so i did and all 30 of my clones died, i used the powder they sold me and did everything he said and they all died and never rooted at all. what did i do wrong? was i suposed to soak the cubes or leave them dry when i put the clone in? or is rockwool the wrong stuff to use for cloning? |
