Aptus Plant-Tech logo- Partner of Hydrofarm Commercial

Nations across the earth are experiencing the negative effects of decades of synthetic fertilizer and pesticide usage. Salt build-up creates harmful runoff into our groundwater, pesticide residue is on much of our produce, and our food lacks the nutritional value it contained only a few decades ago.

Aptus technologies were developed in an effort to fix these problems short term and long term by creating highly available forms of nutrients.

The Aptus rise to prominence is built on True Plant Science, which extends into our philosophy, our technologies, and our approach. The result is growers experiencing quality, efficiency, and cost savings alike.


We strive for excellence in everything we do. This applies to products, client service and quality of our public image and beliefs.

Aptus grow nutrients are engineered to provide optimal nutrient sequencing and micro life stimulation to grow cannabis plants to their maximum potential.
