“In this comparative test on GrowZorb growing substrate, the growth tests on the finalized formulation of SN fine cell crushed with seedlings started in rockwool plugs showed no differences in growth over the 36 day period when compared to the standard greenhouse industry rockwool product.”

It so nice to finally have a growing medium that allows the roots to breathe and grow naturally. You will not regret switching to the zorb, it is so easy to use and prepare. Did I also mention it is reusable. Go ahead and your growzorb you will not go back to anything else.
Made the switch...
Made the switch from soil to the Growzorb product and what a difference. Save time and energy with cleanup and tray prep. Thank you Growzorb your product is AWESOME!!!
