Plant Doctor Water Crystals

Plant Doctor Water Crystals increase the plant available water holding capacity, aeration balance
and structure of soils, substrates and potting mixes. Consequently, water and nutrients are
available to the plant for a longer period of time, resulting in stronger and healthier plant growth
even under hot and dry climatic conditions.

As Plant Doctor Water Crystals store water in the root zone, water deep percolation as well as
fertilizer leaching can be prevented. This allows for a reduction in irrigation frequency and thus
irrigation costs. Furthermore, Plant Doctor Water Crystals increase soil porosity and enhance the
water infiltration rate of soil to an extent that surface water run-off and soil erosion can be
significantly reduced.
