Do the plant roots have to compete with the hydroabsorbent polymers in TerraCottem for the same water?
No. The hydroabsorbent polymers in the TerraCottem mixture were chosen for, among other things, their ability to absorb, retain and keep water available to plant roots. The hydrogels contained in TerraCottem have absorption tensions which allow plant roots to pick up the water on demand, yet ensure that the hydrogels remain humid over a long period of time and are not dried out by the surrounding soil.
