NOTE: A full case consists of 18 blocks. If you are looking to purchase full cases, simply order in increments of 18. When you add them to your cart you will see that the price has been changed to reflect the discounted case price.
When your seedlings have a couple of small leaves and the roots emerge from the starter cubes, it's time to transplant them into full-sized rockwool blocks. Soak the blocks in pH 5.5 water and insert the cubes in the holes shortly afterwards. Use the 3'' or 4'' sizes if you plan to move up to rockwool slabs later on, or choose the larger 4'', 6" or 8'' sizes to grow plants to maturity.
- Gro-Blocks are similar to a "plant container". Need a 3" pot? Then choose a 3" Gro-Block. Small plants can be fully grown in our larger Gro-Blocks. Holes are perfect size for any 1.5" starter plug. Come in packs labeled with instructions.
- Big Mama is Grodan's largest block ever produced! Big enough to grow a large plant for its entire life. More than twice the amount of wool as our Hugo Block.
