GR-150 is an environmentally safe water absorbent (water absorbing crystals) that soaks up excess  water in the soil and holds it until your grass and plant roots need it.  GR-150 acts as a water reservoir in the soil---one that can be filled and emptied many times.  The use of GR-150 will result in less care and watering for virtually all plant-growing applications. 


Product Features:

  • Holds 80 - 150 times its weight in water in most soils.

Park Landscaping

Premix GR-150 at a rate of 0.75 - 2.5 lbs. per cubic yard of soil. It is important to obtain full hydration of the crystals as quickly as possible to help stabilize the soil structure.
Transplanting Plants

During prolonged transportation of plants, GR-150 can provide an adequate supply of water without any spillage. Pre-hydrate GR-150 by mixing 1/2 cup of crystals with 4 gallons of water. Let stand for 30 minutes. Fill the base of a watertight box to a level of one inch. Remove your plants from their pots and place the root balls into the Gr-150 gel. For bare-root plant transportation, make sure that the gel is firm to allow good aeration of the roots.
Lawn Sodding

Prepare soil for sod. Apply GR-150 to prepared soil at a rate of between 2-10 lbs. per 100 square feet. Rake crystals into soil (optional). Lay sod and water well.
