Cubes must never be saturated- only damp. A 40mm rockwool cube weighs 5g dry, 25-30g when 'damp.' Heavier than that is too wet. Overwet cubes will cause slow growth and may drown the roots, killing the plant.

Stop misting. Open the vents on the humidome if there are any. If none, prop the dome lid up about an inch or so. Once the taproot is established into the rockwool, the humidome can be left off.

Well i germinated 3 Afghan beans last week and now they are in 1.5 inch RW cubes and have grown very very minimally! the little heads have just barely poked out of the top of the cube...i have had my light rack over them and had a clone dome over them for humidity for the entire time. lights have been on 24/7. Misted the dome every day before and after work. Im wondering if im doing something wrong like having the dome on them and they arent getting enough light, or if the lights being on all Rating: 5
