Liners are perfect to use while you are harvesting and for post harvest storage. Use a 27-gallon tote with a liner to collect freshly harvested plant material and transport it around the cultivation center. 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.
