Cultivation valuation: per square foot and per pound

Why per-square-foot and per-pound figures are outputs, not inputs

Owners often ask what a grow is worth per square foot. The honest answer is that buyers do not start there. They start with what the facility earns at current wholesale prices. If it earns money, they apply a multiple. If it does not, they value the building, equipment, and license. Only then does anyone divide by canopy square feet or annual pounds, mainly to compare one opportunity with another.

Accounting firm Withum notes that cultivation forecasts turn on growing space, yield per square foot, and product mix. Those are the drivers. The per-unit value falls out of them.

Step one: cost per pound against today’s price

The first number a buyer asks for is all-in cost per pound of saleable flower. The second is the price you actually realized last quarter. The gap is the business.

Reference prices vary widely by state. The Cannabis Benchmarks U.S. Spot Index stood at $1,088 per pound on 4 September 2026. Colorado’s Department of Revenue set its average market rate for retail flower at $607 per pound for April to June 2026. A national average is no guide to a single state. State price histories are on the page about how oversupply and price compression affect value.

Build cost per pound from the general ledger, not from memory. Include cultivation and post-harvest labor, utilities, rent or facility cost, nutrients and media, testing, packaging, and an allowance for equipment replacement. Divide by pounds that passed testing and were sold. The cost-per-pound calculator follows that layout, and sourced industry ranges are in the guide to cannabis benchmarks.

Step two: canopy and yield set capacity

Capacity is canopy times yield times harvests per year. Cultivation consultant Ryan Douglas wrote in Greenhouse Grower in November 2020 that commercial growers should expect at least 30 to 35 grams of dried flower per square foot per harvest, and that 50 to 70 grams marks a strong operation. That is one practitioner’s benchmark, not a survey. Your own harvest records by room are what count.

How much canopy a license permits depends on the state:

State	How cultivation size is limited	Source
Massachusetts	Eleven tiers by canopy; no licensee may exceed 100,000 square feet of total canopy	Cannabis Control Commission license types
Michigan	By plant count: adult-use Class A 100 plants, Class B 500, Class C 2,000	MCL 333.27959

Plant-count states reward large plants and long vegetative cycles. Canopy states reward density and fast turns. A buyer from one system will misjudge a facility in the other unless the capacity is converted to pounds. See the Massachusetts and Michigan pages.

Illustrative: the same facility at two prices

Illustrative arithmetic only. The multiple is a placeholder to show mechanics, not a market quote, and none of this is an appraisal.

Assume 10,000 square feet of flowering canopy, 50 grams per square foot per harvest, five harvests a year. Annual output is 10,000 x 50 x 5 = 2,500,000 grams, or about 5,512 pounds. All-in cost is $600 per pound.

Line	Price $800 per pound	Price $650 per pound
Margin per pound	$200	$50
EBITDA on 5,512 pounds	$1,102,400	$275,600
Value at an illustrative 3.0x	$3,307,200	$826,800
Value per canopy square foot	$331	$83
Value per annual pound of output	$600	$150

Same building, same team, same yield. A 19% fall in price cut every per-unit value by 75%. That is why a per-square-foot figure from another state, or from the same state two years ago, tells you very little. It is also why buyers use earnings restated at current prices, not a three-year average.

What about replacement cost?

Cultivation facilities are expensive to build. Design and construction firm Next Big Crop estimated an all-in range of $250 to $600 per square foot for a complete indoor facility, in an article updated January 2025. More detail is on the page about cultivation facility build-out costs.

Replacement cost matters in two situations. Where new capacity is genuinely needed, a buyer compares your price with the cost and delay of permitting and building its own, and an operating facility can command something for the time saved. Where the market is oversupplied, nobody would build today, so replacement cost is irrelevant and the improvements are worth what they add to earnings, which may be little.

Note the comparison in the illustrative table. At $800 per pound the business value of $331 per canopy square foot sits inside the range of what the facility cost to build. At $650 it is a fraction of build cost. In that case the money spent on the build is sunk, and no valuation method recovers it.

Real estate is valued separately

If you own the building, value the real estate and the operating business as two assets. The largest cannabis landlord, Innovative Industrial Properties, reported 108 properties, 8.4 million rentable square feet, and $2.4 billion of invested capital, or $283 per square foot, as of 30 June 2026. That figure is what the landlord put in, including tenant improvements it funded. It is not what those buildings would sell for today, and the same supplement shows the company working through tenant defaults.

A buyer of your operating company will charge the business a market rent before computing EBITDA, then value the building on its own terms. The mechanics are covered under how real estate control affects value and cannabis property values and cap rates.

What raises or lowers a grow’s value

• Cost position. A grower in the lowest-cost third of its state keeps earning when prices fall. One in the top third does not.
• Sales quality. Contracted or branded sales to retailers deserve more weight than spot sales to distributors. Aged receivables from struggling stores are written down.
• Test history. Repeated failures for microbials, pesticides, or potency labeling cut both yield and credibility. See how compliance history affects value.
• Power and HVAC condition. Deferred maintenance is a price deduction, dollar for dollar.
• 280E exposure. Cultivation fares better than retail because most production cost is inventoriable, but the allocation must survive scrutiny. See how 280E affects valuation.
• Inventory. Flower and biomass are counted and priced at closing at current wholesale, separately from the business. See inventory and biomass at closing.
