Water Retention Gel/Crystal for Plants

Brief introduction

This article is about water retention gel for plants, water retention gardening gel, water retention crystals for plants.


Water Retention Gel/Crystal for Plants (What is it?)

It is a non-toxic environmental protection material with a granule appearance;

It can absorb lots of water;

After absorption, it becomes a water gel form.;

Water gel would release water to plants when it’s drought;

After releasing, water gel would become granule form and could absorb water again for plants.

Applications (where to use?)

For Seed

To improve seed germination & emergence, give plants an early, healthy start.

For Crops

To improve the drought resistance and increase the yield.

For Trees

Fruiter: increase the yield and reduce the fruit cracking rate;

Young or transplanted trees: increase the survival rate.

For Landscape & Golf Grass

To control the cost by reducing irrigation frequency.

How Does It work?

Water Side

It can absorb and store water for plants — just like a mini-reservoir.

Soil Side

1. improve the water retention of soil;

2. keep the soil warm (as water’s high heat capacity);

3. loosen the soil (water retention gel’s going to swell while absorbing water).

Fertilizer Side

1. It contains potassium;

2. It can release fertilizer efficiency slowly.

Water Holding Capacity Test?

Test Objective
Performance Study in varying soil classifications.

Sample Volumes Used
Soil:500ml; Water:750ml; PackRain: 5 grams.

Test Samples:

Sample Type % Sand % Silt % Clay Control weight (g) w/PackRain (g)
1 Sand 100 0 0 762 769
