Good info!
I plan on using a rockwool "starter plug"(?) for the seedling then moving into a larger cube. Will i need to wait until roots show thru before this transfer takes place? will nutrients be introduced at the time of transplant?
Newbie here...bout to crack 3 seeds of widow. using a hydroponics drip system with claypellets. how should I water the rockwool and how often/much to water seedling until sprouting occurs?
