Hydroponic Plants Thrive in Our Stabilized Growing Media

Grow-Tech’s products won’t clog your filters.


Hydroponic growing media should do many things: wick and retain water, provide a stable pH, drain well, and maintain their structural integrity to keep your system clean. Grow-Tech offers the hydroponic grower two product lines with these characteristics, the FlexiPlug® and BioStrate® Felt.

The FlexiPlug growing medium is optimized for all industry standard systems: Nutrient Film Technique, Ebb & Flow, Deep Water Raft, Aeroponic, and Drip. Call us to discuss your specific crop needs.
