On a dry weight basis
On this page11
The construction
The hemp definition sets a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis. The pending amendment changes what is measured and keeps that construction.
Dry weight is not shipped weight
It is the mass with the water taken out. A flower at 12 percent moisture and the same flower at 6 percent have different shipped weights and the same dry weight.
Which makes the test stable and the sample not
The legal basis is the stable number. The thing you put on a scale is the one that moves with the room.
And a container is a moisture device
A sealed jar holds the moisture the flower went in with. An unlined lid lets it equilibrate with the room over weeks.
So the container does not change the legal number
Which is the point worth being precise about. Drying does not move a dry weight concentration, and neither does a better seal.
But it changes everything a buyer cares about
Weight sold, texture, aroma and whether the flower crumbles. Those are moisture outcomes and they are the container's business.
Which is the useful separation
The law measures on a dry basis and is indifferent to your closure. Your customer measures on an as-received basis and is not.
Two directions of failure
Too dry and the flower is harsh and light. Too wet and you have a microbial problem. A container holds whatever it was sealed with, which means the drying has to be right first.
Our shelf can hold a moisture condition
73 heat induction seal liners and 41 F217 out of 260 closures. Both are real barriers and both have to be asked for by name.
And 54 of 260 cannot
26 recorded as No Liner and 28 with nothing recorded. For a product whose defining property is a moisture condition, that is the half of the shelf to avoid.
