Lean for cannabis operations · clone to counter · free

Less waste per gram.

Most cannabis operators that close don't lose to the plants. They lose to everything around the plants: strains nobody reorders, flower waiting on a dry room, bud hand-trimmed for pre-rolls. Lean has had the tools for that for decades. I run continuous improvement at a cannabis company in Massachusetts, and this is where I write those tools down in cannabis terms.

The 8 wastes of a grow

Lean names eight wastes, remembered as DOWNTIME. Here is what each one looks like between the clone and the counter, and the question that finds it. Walk one batch with these in your pocket before you fix anything.

DDefectsFailed micro or pesticide tests, mold and bud rot, remediation, a wrong weight or label, a tag that doesn't match the package.Ask: what did we remediate, rework or destroy last month, and where did it start?

OOverproductionStrains nobody reorders, grown anyway. Pre-rolls made ahead of orders. More flower harvested than packaging or the market can take.Ask: which strains from the last cycle are we still holding?

WWaitingTrimmers idle until the dry room releases. A lot still in the vault days after its results came back. Veg ready, but the flower room hasn't turned.Ask: where does a batch sit with nobody touching it?

NNon-utilized talentExperienced growers doing data entry. The trimmer who knows why bin weights drift and was never asked. Compliance staff retyping what the system already holds.Ask: who on the floor already knows the answer, and has anyone asked them?

TTransportationCarts and plants moved between rooms more than the process needs. Flower in and out of the vault between every step. Dry, trim and packaging at opposite ends of the building.Ask: how many times does a batch go in and out of the vault before it ships?

IInventoryFlower aging in the vault, losing weight and terpenes. Trim and biomass waiting on extraction. A packaging cage full of materials for SKUs that changed.Ask: how old is the oldest lot in the vault, and why is it still here?

MMotionTrimmers walking for bins, scales and totes. Techs hunting for tools or nutrients. Packaging operators reaching across the table for every unit.Ask: how many steps does a trimmer take to finish one bin?

EExtra processingHand-trimming flower that ends up in pre-rolls or extraction. Weighing a batch more often than compliance requires. Reports printed for a meeting nobody holds.Ask: which steps would the customer never pay for if they saw them?

The same 8 wastes, room by room

By area

A vertically integrated operation is five operations under one roof, and each one wastes in its own way. Each guide goes deeper: what every waste looks like in that area, how to measure it, where to look, and the first thing to try. Each has its own walk sheet.

Take it on a walk

Each walk sheet is one printed page: the eight wastes, where to look, the question to ask, and room to write what you saw. There's one for the whole operation and one for each area. Walk one batch, write down what you see, and bring the sheet back to your team. No solutions yet. That comes after you've looked.

The market, from the outside

Why this matters now

My report on the Massachusetts market covers the squeeze from the outside: oversupply at both ends and prices that keep falling. Everything on this page is about the inside, the part you control.
