GrowZorb Grind

GrowZorb Grind is comprised of ground up GrowZorb foam. It is well suited for starting seeds and cuttings and can be used wherever coco coir and rock wool are used, in other words, it could be used in just about any hydroponic growing application.

GrowZorb Grind can be used many times over, simply knock the grind from the roots and or wash it out in a bath of water then pour it into a pot that has drain holes and you are ready to go. It gets better the more often you use it, the fine leftover root matter that doesn’t get washed out helps establish a healthy growing environment. If there is any concern about pathogens it could be sterilized during the wash process.

GrowZorb Grind is ideally suited for automated watering systems.  If used in traditional flower pots it will require more frequent watering.

300 grams of GrowZorb grind will net approximately 1.0 US gallons of placed medium.  It can be fluffed up or compressed for a looser or tighter Matrix.
