The 2-way humidity control products of Integra BOOST have been developed with your needs in mind. Simply place your Integra product in a closed room together with your plant. Because our products are salt-free and leak-proof, you can place our Integra BOOST packs directly into a container or glass jar next to your herbs to absorb and/or provide excess moisture when needed. Integra BOOST begins to regulate the humidity inside the container to protect your best buds from mold and rot (due to excess moisture) or dehydration (due to lack of moisture). Replace it with a fresh pack when the dot on the replacement indicator card supplied turns light blue. Done!
