CANNABIS 101

How should you store cannabis at home?

Airtight glass, out of direct light, somewhere cool and dry. A cupboard beats a fridge, because condensation does more harm than warmth. Stored that way, flower holds its aroma for six to twelve months.

What degrades it

EnemyWhat it doesWhat to do
LightBreaks down cannabinoids fastest of allOpaque container, or a dark cupboard
AirOxidises THC into CBN over timeAirtight, and not a jar half-empty for months
HeatDrives off the volatile terpenesRoom temperature, away from appliances
HumidityToo high grows mould; too low turns it to dustAround 60% relative humidity
HandlingKnocks the trichomes offHandle by the stem, not the flower

Why old flower feels sleepier

THC oxidises into CBN as it ages, and CBN is associated with heaviness rather than headiness. Nothing has gone wrong; the profile has simply moved.

The non-negotiable

Store everything locked and out of reach of children and pets. Edibles in particular look exactly like the confectionery they are modelled on.

This is not medical advice. Nothing here is a therapeutic claim, and nobody at Cannalab47 is qualified to give one. Cannabis affects people differently. Adults 21+ only.
