Flower storage
Airtight glass jar. Boveda or Integra humidity pack inside (58-62% RH). Stored at room temperature. Away from direct light. The original Michigan dispensary jar is sealed and often opaque — keep flower in that until you switch to a larger storage jar. Plastic bags kill terpenes within 2-4 weeks.
Pre-roll storage
Original tube, sealed. Once opened, smoke within 2 weeks. Pre-rolls are vulnerable to drying because the tube has minimal air seal. If you bought a 10-pack and plan to stretch it over a month, drop a humidity pack in the original packaging.
Vape cart storage
Cool, dark, vertical. Heat thins the oil; vertical storage prevents the wick from drying. Avoid leaving carts in a hot car. Used carts can last 4-6 weeks at peak quality after first puff. Distillate carts hold longer than live-resin carts because there's less to lose.
Edibles storage
Original packaging, sealed, room temperature. Chocolates can be refrigerated to extend shelf life. Gummies kept open will get tacky and lose dosing accuracy. Most Michigan edibles list a best-by date 6-12 months from manufacture.
Concentrate storage
Original silicone or glass container, cool, dark. Live rosin and live resin keep peak quality 6 months refrigerated, less at room temp. Distillate is shelf-stable for over a year.
