  1. Using a sharp edge instrument, cut an “X” in the top of the wrapper where the well rooted Grodan Gro-Block will be transplanted to. Create two drainage slits on the bottom of the bag by cutting a small short straight slit on each of the corners of the bottom of the foil bag.
  2. Fill the Grodan Gro-Slab bag with a nutrient solution of roughly 1.5 EC and 5.5 pH and let stand until fully saturated.
  3. Place a well rooted Grodan Gro-Block with white roots emerging directly on the Grodan Gro-Slab where the “X” cut was made. Ensure the foil from the cut to rest up the sides of the block.
