Recommended Products for Cannabis
These AgConcepts biological inputs are specifically matched to the nutrient demands and growth cycle of Cannabis during the Spring-Summer season.
Enhance
FoliarFoliar fertilizer that delivers phosphate and essential nutrients directly through the leaf — applied during vegetative-to-reproductive transition for maximum crop response.

ZyDrive
BiologicalIn-furrow and seed treatment biological inoculant that delivers nitrogen-fixing bacteria, phosphate solubilizers, and mycorrhizal fungi directly at the germinating seed.

ProMax
BiologicalOMRI-Listed organic soil fungicide and nematicide powered by thyme oil — zero REI, zero PHI, proven for potatoes, vegetables, and all row crops.

Application Guide for Cannabis
At Planting / Transplant
Apply ZyDrive in-furrow or as a soil drench at transplant to establish nitrogen-fixing bacteria, phosphate solubilizers, and mycorrhizal fungi in the root zone before the crop sees its first stress event.
Vegetative Growth
Apply Enhance as a foliar spray during active vegetative growth to deliver phosphate and essential micronutrients directly through the leaf — timed to the period when the crop's nutrient demand is climbing fastest.
Reproductive / Pre-Harvest
Apply ProMax (OMRI-Listed, PHI 0 days) to suppress soil-borne pathogens and foliar disease pressure through the critical reproductive window and up to harvest day — with zero re-entry interval and zero pre-harvest interval.
Cannabis Farm Operations Snapshot
What it takes to run a typical Cannabis operation — equipment, inputs, and cost benchmarks.
Typical Scale
1–25 acres (outdoor) / 5,000–50,000 sq ft (indoor/greenhouse)
Avg Yield
1–3 lbs/sq ft (indoor) / 1,000–2,000 lbs/acre (outdoor)
Gross Revenue/Acre
$250,000–$1,000,000+ (indoor) / $50,000–$200,000 (outdoor)
Total Input Cost/Acre
$80,000–$400,000 (indoor) / $15,000–$60,000 (outdoor)
⚙ Key Equipment
- 💡
LED Grow Lights
Primary energy cost in indoor ops; full-spectrum LEDs at 600–1,000 µmol/m²/s
- 🌬️
HVAC / Dehumidification
VPD management critical for yield and disease prevention; largest fixed cost
- 💨
CO₂ Enrichment
1,200–1,500 ppm during lights-on; significant yield driver in sealed rooms
- 💧
Fertigation System
Automated drip or flood-and-drain; pH/EC monitoring at every irrigation event
- ✂️
Trimmers / Buckers
Hand-trim for premium flower; machine trim for commodity; largest labor cost
Equipment specs represent a typical mid-size operation. Scale up or down as appropriate.
$ Cost Per Acre Breakdown
📋 Key Inputs & Costs
Base Nutrients
$8,000–$25,000N/P/K nutrient solution; pH management is a full-time operational task
pH Adjustment
$1,000–$3,000pH Up/Down; cannabis is pH-sensitive at 6.0–7.0 (soil) or 5.5–6.5 (coco/hydro)
Biological Inputs
$2,000–$8,000ProMax (OMRI/PHI 0), ZyDrive (root biology), Enhance (foliar terpene/cannabinoid support)
Grow Media
$5,000–$20,000Coco coir, rockwool, or living soil; media choice affects biological program selection
Trellis / Support
$1,500–$5,000SCROG nets or bamboo; required for indoor canopy management and light penetration
💧 Water Needs
Heavy — 1–6 gallons/plant/day. Indoor operations use recirculating systems or hand-water. Outdoor may rely on drip irrigation.
🧬 Where Biologicals Fit
ProMax OMRI-Listed status with PHI 0 days and REI 0 hours enables clean residue test results — critical for state compliance. Enhance applied during vegetative-to-pre-flower transition supports terpene and cannabinoid density. ZyDrive improves root-zone biology in soil and coco grows, reducing nutrient lockout and improving uptake consistency.
Pro Tip
ProMax's PHI 0 days means it can be applied up to harvest day without residue concerns — critical for state mandated testing compliance. Most synthetic pesticides carry PHI restrictions that create a dangerous gap between last application and harvest.
