Liners are perfect to use while you are harvesting and for post harvest storage. A 55-gallon drum liner can be used after properly drying and sweating your cannabis for bulk storage and curing. These bags are completely opaque to keep out harmful UV light and have added anti-static properties to prevent trichome loss. Simply using a liner can prevent cross contamination from batch to batch limiting your product loss from unforeseen pest and mold issues. Using a Grove Bags liner will protect your product and your bottom line.
