I finally got a seed to sprout in a rockwool cube. It just popped up today. What’s the next step? How long should I leave it in the humidity dome. Which I am using the jiffy green house container for the dome. Thanks guys!
Distilled water only; very easy to overwater in rockwool. Use a spray atomizer and mist the dome twice a day to provide all the moisture plant needs. Seedlings derive their water from the air until a taproot forms (ten days or so). Seeds carry enough nutrients to carry them to first transplant.
Hope that helps.
