Hemp is one of the most versatile crops in American agriculture — but getting the nutrition right is what separates a good harvest from a great one. That's where Dosatron comes in.

Whether you're running a small indoor hydroponic setup or managing acres of outdoor hemp, Dosatron systems scale with your operation. From 2 GPM for hobby growers to 1,200 GPM for large-scale field applications, there's a configuration built for the way you grow.
Below, you'll find recommended installations, support resources, and the products trusted by hemp growers across the country.
Since the signing of the 2018 Farm Bill, hemp has rapidly become one of the most promising crops for American farmers. Scaling outdoor operations requires fertigation equipment that's powerful, reliable, and easy to maintain — even in remote field conditions. Dosatron's water-powered injectors need no electricity, making them ideal for outdoor installations where power access is limited. Our systems handle everything from single-line setups to high-capacity parallel configurations. Spotlight — D400 Mega-Flo Series Meet the newest addition to the Dosatron lineup. The D400 Mega-Flo delivers up to 400 GPM per unit, with an injection range of 0.003%–0.5% (1:30,000 to 1:200). Install up to three D400 units in parallel to reach 1,200 GPM — the perfect fit for large-scale outdoor hemp operations.
Whether you're growing from seeds or clones, in a warehouse or a greenhouse, creating the right nutrient mix is a delicate science. Dosatron injectors give your plants the exact amount of nutrients they need — every time, every cycle. Our full product line lets you automate multi-chemical fertigation programs with fine-tuned accuracy and repeatable results. No more measuring, no more pouring, no more guessing. Spotlight — Nutrient Delivery System (NDS) The Dosatron NDS is a modular system built around four main panel sections, fully configurable to match your fertigation program.
