Larger rack systems sit in our drying racks collection, and more equipment is in vacuum sealers, drying ovens and freeze dryers. All of it belongs to the wider Harvesting + Processing range.

Types of Drying and Preservation Gear

Drying Racks and Trays

The Common Culture rack hangs six 24 in mesh tiers and folds to 3 in for storage. The Hydrofarm StackIt holds stems on 28 stainless clips, rated to 0.8 lb per clip. Twister stackable handling trays move material between rooms.

Curing Containers and Desiccants

The Integra Boost 5 gallon bucket cures up to 4 lb with 30 desiccant packs under an O-ring lid. Curetube tubes add a burp lid and hygrometer. The Auto Cure Large holds 20 to 25 lb in a 32 cu ft chamber and vents itself when a set threshold trips.

Freeze Dryers, Vacuum Ovens and Bags

Harvest Right freeze dryers run from Small to X-Large, with pharmaceutical models too. BVV and Across International vacuum ovens cover lab-scale drying. Dry & Mighty bags, NatureVac vacuum bags and Common Culture turkey bags seal the finished product.

How Growers Dry and Cure

Oregon State University Extension describes slow drying at 64 to 70 °F and 50 to 55% relative humidity in a well-ventilated space. It cites a study that cured flower at about 64 °F and 60% RH for 14 days. Keep air moving gently around the racks rather than aiming a fan straight at them. A hygrometer in each curing container shows when to burp or vent.

Frequently Asked Questions

What is a curing rack?

It holds dried material in thin, open layers so air moves around it while it finishes. In this collection, the Common Culture mesh rack and Twister trays fill that role. The Auto Cure unit goes further, with sealed perforated trays and automatic venting based on humidity or time.

What can a small freeze dryer handle?

Harvest Right rates its Small model at 6 to 10 lb of fresh plant material per batch. That adds up to 1,800 lb per year on 434 sq in of tray space. Medium, Large and X-Large models scale up from there, and pharmaceutical versions are available for lab use.

How should you store dried flower after harvest?

Keep it sealed, cool and dry. Oregon State University Extension suggests about 64 °F and 45 to 55% relative humidity for storage. Dry & Mighty bags use triple-laminated LDPE and can be heat or vacuum sealed, and NatureVac bags fit standard vacuum sealers.
