Check List:

  2. Squeeze 40 – 50% moisture from cubes leaving them wet but not dripping. 
  3. Carefully place each seed into the rockwool cube hole root down, ensuring good root to cube contact. 
  4. Peel a small piece of rockwool from the side of the cube and cover the hole. 
  5. Re-hydrate the cubes with that fresh Clonex Mix to ensure good moisture to the root and cube. 
  6. Spray Clone dome lid with R.O or dechlorinated water and replace on the tray, making sure there is a tight seal.
