fishman3811 Reviewed by fishman3811 on . Rockwool Dampness While using rockwool, I have noticed it will almost NEVER dry out, even if you let it sit in the sun for like a week. It stays SO wet. Is this supposed to be this way even when you have little seedlings and little plants who DONT need over watering? Do I just KEEP feeding them water, pumping it through the rock wool with my drip system? :\ Rating: 5
