Urth & Fyre has achieved 95%+ microbial pass rates across 250,000+ sq ft of commercial cannabis canopy in Nevada and Michigan. We deliver custom SOPs, on-site training, and cost-effective pathogen mitigation systems — without the $100K–$500K equipment price tag.
Cannabis microbial failures aren't random. They're predictable — and preventable. Most operators respond to a failed batch by spraying more product, running more remediation, or purchasing expensive UV, ozone, or radiation equipment. These are symptoms treatments, not root cause fixes.
The real drivers of chronic microbial failures are almost always upstream: poorly designed irrigation systems that harbor biofilm, build materials that can't be properly sanitized, environmental conditions that create condensation and mold-favorable humidity, and SOPs that look good on paper but aren't actually followed on the floor.
Urth & Fyre takes a forensic approach. We identify the actual source of contamination in your facility — not the surface expression of it — and implement multi-layered interventions that address the problem permanently.
The result: consistent 95%+ pass rates without $100,000+ equipment purchases. Our solutions are cost-effective, implementable within your existing CAPEX/OPEX framework, and designed to last.
The cannabis industry has seen an influx of expensive microbial mitigation technologies: RAD Source irradiation systems ($100k–$500k), ozone generators, peroxyacetic acid foggers, and UV-C systems. These tools have a place — but they are not a substitute for proper facility design and operational discipline.
Facilities that rely exclusively on post-harvest remediation or high-capital equipment will continue to fail intermittently because the contamination source is never eliminated. Remediation treats finished product. Our approach eliminates the conditions that create contaminated product in the first place.
Urth & Fyre interventions are grounded in ASTM D8219 (Standard Guide for Cleaning and Disinfection at Cannabis Cultivation Centers) and ASTM D8197 (Standard Specification for Maintaining Acceptable Water Activity in Dry Cannabis Flower). We bring industry-standard rigor to every engagement.
VPD management by growth stage (W1–3: 0.8–1.0 kPa; W4–6: 1.0–1.2 kPa; W7–9: 1.2–1.6 kPa). HVAC phasing, sensible/latent load calculations, and condensation elimination.
Chlorine dioxide (ClO₂) programs for irrigation lines, surface sanitation, and room fumigation. Protocol selection based on pathogen type, surface material, and operational constraints.
Flush and bleed valve specifications to eliminate biofilm reservoirs. Proper line sizing, slope, and material selection (stainless steel vs. PVC Sch 40/80) to prevent microbial colonization.
Dry and cure environment design targeting aw 0.55–0.65 per ASTM D8197. Measurement protocols using calibrated Aqualab meters. SOP integration for harvest-to-cure transitions.
Material specification for new builds and retrofits: IMP vs. drywall, stainless steel vs. painted surfaces, flooring and drainage design. Build materials that can actually be sanitized.
Custom SOPs for room turns, ongoing sanitation, harvest transitions, and irrigation maintenance. On-site staff training and documentation systems that create accountability.
VPD mapping across all growth stages and zones • HVAC capacity and zoning analysis • Condensation risk assessment • Air exchange rates and positive/negative pressure verification • Temperature and RH data logging review
Biofilm risk assessment in distribution lines • Flush and bleed valve placement • Water treatment system evaluation • ClO₂ injection point specification • Line material and sizing review
Dry room environment design • Water activity measurement protocol • Cure environment temperature and RH targets • Packaging timing relative to aw • Long-term storage environment specification
Surface material sanitizability assessment • Bench, floor, and wall material specification • Equipment selection for sanitation compatibility • Room-to-room cross-contamination risk mapping • Spray equipment specification (stainless steel only)
We review your facility layout, test data history, current SOPs, equipment specs, and environmental records before we arrive. On-site, we conduct a comprehensive walk-through covering every system that touches microbial outcomes.
You receive a prioritized, costed intervention plan. We identify quick wins that can be implemented immediately and structural changes for long-term compliance. Every recommendation includes implementation guidance and expected impact.
We stay with you via phone and video through implementation. SOPs are written, staff are trained, and protocols are verified. We remain engaged until your facility achieves a 95%+ pass rate — this commitment is built into our MSA/SOW.
Urth & Fyre has achieved 95%+ microbial compliance rates across more than 250,000 sq ft of commercial cannabis canopy in Nevada and Michigan — facilities operating under <10,000 CFU/gram Aspergillus failure thresholds, post-May 2023 regulatory implementation.
Our results are documented, verifiable, and built on reproducible systems. The same frameworks we used in Nevada and Michigan are available to your operation. Operators who implement our full protocol achieve consistent compliance — not single-batch remediation.
View the Case Study →A single failed batch at a mid-size facility can represent $50,000–$250,000 in lost revenue. Chronic failure rates compound that loss across every harvest cycle. Before spending on remediation equipment, calculate what microbial compliance is actually worth to your operation.
