Of course you don't let it sit in water,anything pourass can become over saturated, but if you use a flood and drain system and soak for 15-30 minutes per watering, there is NO way to over water with rockwool
vegasgrower Reviewed by vegasgrower on . Rock wool dampness During seedling stage, should the rockwool be kept wet, or let to dry between waterings? How about after veg starts? I had a 1 inch blueberry that died overnight and the wool was dry. PH was around 5.8 and using miracle grow for the seed stage. Any help? Thanks! Rating: 5
