Grodan Rockwool is consistent, sterile, and provides a perfect ratio of media to aeration. As a result, commercial farms yield more per square foot and with less variation in harvest weight.
These are 6" x 6" x 6" Pargro "Biggie" Blocks with holes that come 64 unwrapped blocks/case.Pargro is a lower-priced option to the GR32 Improved, yet outperforms competing RedRock or Owens Corning Vidawool products.
We do not ship these UPS. They can be will-call picked up or delivered by our Fleet or common carriers (pallet is 8 cases to optimize for freight).
