Like recipes, our feeding programs contain different base nutrients and supplements that complement skills, preferences, and desired outcomes in the garden. Medi One is our organic-based 1 part, while our 2 part Dual Fuel, 3 part GP3, and 4 part Hydro Fuel are all synthetic-based feed programs. We have also partnered with AutoPot Watering Systems to create an AutoPot Dual Fuel and AutoPot GP3 feed program tailored specifically for their grow systems. Lastly, we have a feed program with products formulated for the demands of outdoor growers called Backcountry Blend. Choose your feed program based on your current skill level and best fit for your garden.

The icons found on the front of our bottles indicate whether it is a dry or liquid
