AirFeed captures nitrogen from the air. The Pellet handles everything else — phosphorus, magnesium, and the trace minerals your plants need to thrive. Drop one in, and your reservoir becomes a complete liquid fertilizer system for 30 days.
No mixing, no measuring, no equipment. The Pellet is sized to fit the AirFeed reservoir chamber. Drop it in and close the reservoir.
The Pellet is formulated for slow, even dissolution — releasing phosphorus, magnesium, and trace minerals into the reservoir liquid at a steady rate across the full month, not all at once.
The nitrogen from AirFeed's catalyst mesh combines with the Pellet's P, Mg, and trace minerals in the reservoir liquid. What comes out of the delivery outlet is a complete balanced fertilizer — not just nitrogen.
When the Pellet has fully dissolved (approximately 30 days), drop in a new one. That's the full monthly maintenance routine for complete plant nutrition.
AirFeed Complete adds a second active mesh layer upstream of the primary catalyst. The result: a single sealed unit delivering nitrogen, potassium, silicon, humic acid, phosphorus, magnesium, and a full trace mineral profile — simultaneously, passively, from the air and a monthly Pellet.
The base AirFeed uses a single catalyst mesh (Layer 2) for nitrogen fixation. AirFeed Complete adds a surface conditioning mesh (Layer 1) positioned between the air intake and the catalyst. Layer 1 pre-conditions incoming air by collecting additional atmospheric moisture and contributing potassium silicate and humic acid to the liquid before it reaches the catalyst layer.
The complete nutrient profile from a single passive device — no electricity, no mixing, no store trips.
AirFeed, BoltBrew, AirFeed Complete, AirFeed Pellet, and The Vessel — five products, one ecosystem.
