Six areas that make or break a grow operation.
The Grow Lifecycle
Five phases from propagation to harvest
Environmental Controls
Temperature, humidity, light, VPD, CO₂
Nutrients & Feeding
Veg vs. flower inputs, pH, EC
IPM & Quality Control
Pest prevention, testing, recalls
Compliance & Tracking
Seed-to-sale, Metrc, SOPs
Common Pitfalls
What kills margins and how to avoid it
Five phases. Every grow, every time.
Seeds vs. clones — choosing your starting point.
Every grow decision gets locked in before you put anything in soil.
Genetic diversity, slower start
Feminized seeds reduce risk. Auto-flower strains compress timelines. Germination in 3–7 days; seedling stage 1–2 weeks.
Genetic consistency, faster entry
Mother plant program required. Root in 7–14 days. Inherit both traits and pathogens — quarantine protocol is non-negotiable.
Propagation room standards
72–78°F · 70–80% RH · 18 hrs light (low-intensity CFL or T5) · pH 5.5–6.2 for media
Tag it before it touches soil
In most states, plants must be tagged in your seed-to-sale system (Metrc) from propagation. Do not wait until flower to log.
Build structure now. Fix nothing in flower.
The flip. 12/12. No going back.
Transition
Stretch phase. Plants can double in height. Trellis now. Begin P-K ramp-up, reduce N.
Bulk
Peak resin production. High P-K, low N. EC 1.8–2.4. Defoliate strategically for airflow.
Ripening
Flush or taper nutrients. Monitor trichomes: cloudy = near peak. Amber = THC degrading.
Key metric: VPD 1.2–1.6 kPa in flower. High humidity invites botrytis. Lower RH to 40–50%.
You grew it. Now don't ruin it.
Post-harvest is where most quality losses happen. Slow down here.
- Harvest timing: Trichome color is your primary indicator. Invest in a loupe (60–100×). Harvest by phenotype, not by calendar.
- Wet vs. dry trim: Wet trim = faster, machine-friendly. Dry trim = better terpene preservation. Know your market before you decide.
- Drying: Target 60°F · 60% RH · 10–14 days. No fans blowing directly on buds. Slow drying = better terp retention and smoother smoke.
- Curing: Glass jars or CVaults. Burp daily for the first 2 weeks. Cure minimum 4–8 weeks for top-shelf product. Boveda 62% packs maintain humidity.
- Testing: Send samples before packaging. Potency, terpenes, pesticides, heavy metals, microbials. Failed tests kill your batch and your reputation.
The environment is the crop.
Feed the stage, not the plant.
High N, moderate P & K
Nitrogen drives leaf and stem growth. EC 1.2–1.8. Feed every 2–3 days. Always check runoff pH.
Low N, high P & K
Phosphorus and potassium drive resin and bud development. EC 1.8–2.4. Taper N starting week 3 of flower.
Final 1–2 weeks
Reduce or eliminate nutrients to clear residuals. Flushing remains debated — organic grows may not need it. Monitor runoff EC.
The gatekeeper of all nutrients
Soil: 6.0–7.0 · Hydro/coco: 5.5–6.5. pH outside these ranges locks out nutrients regardless of what you're feeding.
Measure input & runoff
High runoff EC = salt buildup. Flush if runoff is 0.5+ above input. Low EC = underfeeding. Keep a feeding log every batch.
Living soil changes the math
Microbe-driven systems buffer pH naturally. Less precise control but more forgiving. Test soil before inputs, not just water.
The regulators are in your grow room. Act like it.
These are just guides. Consult a compliance attorney and your state's DCC.
- Metrc (or your state's system): Every plant over 8" must be tagged. Every batch must be logged. Gaps = violations. Violations = license risk.
- SOPs are your compliance backbone: Documented procedures for every grow operation. Inspectors will ask. "We just know how to do it" is not an answer.
- Waste tracking: All cannabis waste must be logged and destroyed per state regs. Rendered unusable (typically 50/50 with non-cannabis material) before disposal.
- Third-party testing before transfer: COA required before product moves to distributor or retailer. Results must match manifest weights within variance tolerance.
- Inventory reconciliation: Scheduled and surprise audits compare your physical inventory to Metrc. Discrepancies over tolerance thresholds trigger investigations.
What kills margins.
Leave with these three things.
Document everything.
SOPs, feeding logs, Metrc entries, scout reports. If it isn't written down, it didn't happen — in court and in compliance.
The environment is the crop.
Master VPD, temperature, and air exchange before you spend money on fancy nutrients. Plants will tell you what they need — if the climate is right.
Slow down post-harvest.
Quality is made or destroyed after the chop. Rushing dry and cure is the fastest way to turn premium genetics into mid-shelf product.
