Harvest Batch Costing
Cannabis cultivation is naturally organized around batches. Each harvest lot picks up cost from clone or seed through vegetative growth, flower, harvest, dry, cure and trim. We attach cost to the batch across its full life so finished inventory carries a real, defensible unit cost instead of a plug figure.
The batch model also produces the number cultivators care about most: fully loaded cost per pound, broken out by stage and cost category. Once that number exists, decisions about lighting, nutrients, labor scheduling, strain mix and room utilization stop being guesswork.
- Costs accumulated by harvest lot from propagation through cure
- Direct materials: nutrients, media, amendments, consumables
- Direct labor captured by activity and allocated to batches
- Indirect production costs: utilities, facility depreciation, cultivation management
Inventory Capitalization Under the Producer Rules
A producer capitalizes direct and allocable indirect production costs into inventory. For a New Mexico cultivator, that includes cultivation payroll and burden, power and water consumed in production, nutrients and growing media, depreciation on grow rooms and environmental controls, quality assurance, and the facility cost attributable to production space, whether under a standalone producer license or a vertically integrated one.
Costs outside the production function — sales, marketing, distribution to customers, executive administration — are not inventoriable and are lost at the federal level. We measure the production footprint, document the allocation basis, and keep the study current as rooms are added, converted, or repurposed under the plant-count limits attached to your license.
Work in Process and Biological Inventory
A living plant midway through flower is real value with real accumulated cost, but it is neither raw material nor finished goods. We maintain work in process by room and by batch, roll cost forward each period, and transfer to finished goods once cure is complete.
That discipline keeps the balance sheet honest and avoids the common cultivator pattern of expensing everything as incurred, which produces a phantom loss in a heavy-spend quarter and a phantom windfall the quarter the crop actually sells.
Yield, Shrink and Variance Analysis
Wet weight to dry weight to trimmed saleable weight is where cultivation margin is made or lost, and BioTrack already records every step, so the variance analysis can be built entirely on data the state already requires you to capture.
We report yield per square foot, yield per light, dry-to-wet conversion by strain and room, trim loss, and the value of material routed to waste or extraction grade. Persistent negative variances almost always trace back to a specific room, strain or crew, and once measured they are fixable.
- Grams per square foot and per light by room and cycle
- Wet-to-dry and dry-to-saleable conversion rates by strain
- Waste and destruction reconciled to BioTrack records
- Cost per pound trended by harvest lot
Tax and Compliance Considerations for Cultivators
New Mexico does not levy a separate cultivation tax, which simplifies the tax stack relative to states that layer a per-pound or per-ounce charge on producers. That makes fixed-asset planning and payroll allocation the higher-leverage issues: cost segregation on build-out, correct classification of grow equipment, and the interaction of depreciation with inventory capitalization can move a producer's federal position substantially.
Plant-count limits attached to a producer license also shape the costing model, since capacity is fixed by license terms rather than by square footage alone. We build the cost-per-plant and cost-per-pound analysis around the actual licensed capacity so it reflects the real constraint on the business.
Costing a Harvest Cycle From Clone to Cured Flower
Cultivation accounting is agricultural cost accounting with a tax stake attached. Costs accumulate by cycle: propagation, vegetative, flower, harvest, dry and cure, and trim. Each stage consumes labor, power, water, nutrients and facility capacity, and all of it is inventoriable for a producer. The accounting job is to accumulate those costs against a batch and release them to COGS when the finished flower sells.
A licensed indoor operation running near its plant-count limit on perpetual rotation outside Albuquerque might spend $95,000 a month on power alone. Whether that power is capitalized into inventory or expensed is a mid-six-figure annual tax difference. Getting there requires meter-level or square-footage-based allocation between flower rooms, veg space, dry rooms and the office, documented once and applied consistently.
Yield per square foot and cost per pound by cycle are the two operating numbers that matter, and they can't be computed at all unless batch costing exists. Operators who track them make different decisions about strain selection, light schedules and labor scheduling than operators who look only at a monthly P&L.
- Batch-level accumulation of labor, power, water, nutrients and amendments
- Depreciation of lights, HVAC, benching and irrigation allocated to grow space
- Cost per pound and per gram at harvest, by cycle and by room
- Cost release to COGS on sale, with unsold harvest carried as inventory
Outdoor, Mixed-Light and Seasonal Cash Planning
An outdoor cultivator in a market like Deming or Carlsbad has one harvest and twelve months of expense. Nearly all cost is incurred before any revenue arrives, then revenue lands in a compressed window at whatever the fall market pays. Cash planning and inventory carry are therefore the dominant financial issues, and the tax result depends heavily on how much of the harvest sells before year end versus sits in inventory.
Mixed-light operations smooth this partially, with light deprivation producing two or three cycles. Either way, the accounting must carry unsold harvest as inventory at accumulated cost rather than expensing the season, and must apply lower-of-cost-or-market discipline when wholesale pricing falls below cost.
We build a seasonal cash model alongside the cost model: pre-season financing needs, peak working capital, expected sell-through timing and the estimated tax payments those sales trigger. Cultivators who plan the tax payment before the crop sells avoid the most common failure in the segment.
