Recommended Products for Cannabis

Three products, three roles — designed to work together across the cannabis production cycle.

Foliar

Enhance

Vegetative-to-pre-flower foliar nutrition

Foliar nutrition during the vegetative-to-pre-flower transition. Delivers phosphate and essential micronutrients directly through the leaf at the moment nutrient demand is climbing fastest. Supports cannabinoid and terpene density by improving plant nutrition in the weeks before flower set.

Biological

ZyDrive

Root-zone biological inoculant

In-medium biological inoculant for soil and coco grows. Delivers nitrogen-fixing bacteria, phosphate solubilizers, and mycorrhizal fungi directly to the root zone at transplant. Reduces nutrient lockout in buffered coco and amended soil — better root development from day one.

OMRI-Listed Biopesticide

ProMax

PHI 0 days · REI 0 hours · OMRI-Listed

OMRI-Listed organic biopesticide powered by thyme oil. PHI 0 days means it can be applied up to harvest day. REI 0 hours means no re-entry restrictions. Proven protection against soil-borne pathogens and foliar disease without the residue profile of synthetic fungicides.

Application Timing

A 3-stage biological program from transplant through pre-harvest.

01

Transplant

Day 1

ZyDrive

Soil drench or in-medium application at transplant to establish root-zone biology before the plant faces its first nutrient demand.

02

Vegetative

Weeks 2–5

Enhance

Foliar spray 1–2× during active vegetative growth. Apply when lights are off or early in the light cycle to maximize foliar uptake.

03

Pre-Flower

Transition week

Enhance + ProMax

Final Enhance application at flip. Begin ProMax on a 7–10 day preventive cycle through flower. PHI 0 means you can apply right up to harvest.

Why Biologicals for Cannabis?

Residue Testing Pressure

State lab testing is mandatory in every legal market. Synthetic pesticides with non-zero PHI windows create a compliance gap that biologicals eliminate. ProMax's PHI 0 days removes the calculation entirely — apply, harvest, test, pass.

Regulatory Scrutiny

Cannabis is one of the most regulated agricultural commodities in the US. OMRI-Listed and EPA-exempt inputs are defensible at every regulatory level — from state licensing to lab testing to market documentation. Conventional pesticide residues can cost you your license.

Premium Market Positioning

OMRI-grown cannabis commands a price premium in legal dispensary channels. Craft and boutique producers who document biological and organic inputs increasingly command 20–40% higher wholesale premiums than commodity producers using conventional chemistry.

⚠️ ProMax State Registration Note

ProMax is registered in most US states but is currently not available in the following states: Minnesota, North Dakota, Georgia, Kansas, Mississippi, Montana, New Jersey, South Dakota, and Wisconsin. If you are in one of these states, contact us — we can recommend alternative biological programs using Enhance and ZyDrive that remain fully effective and compliant.
