Howdy Student,

You said: "I then placed them into my hydro setup (DWC). I set the water level so that it was about 1/2 inch to 1 inch below the bottom of the rockwool cube. I left the water level there until I could see roots growing out of the net pot into the water."

I'm wondering..where did you set the water level,once the roots grew out of the net pot and reached the water ?

Have a good one...Torog
