Coolsox is designed to evenly disburse air into your grow space through hundreds of pre-perforated holes. This creates a blanket of cool air that pushes the hot air upwards and away from your plants. Coolsox can be snugly fitted around right-angle corners, up walls, across ceilings, or woven between your plants. Unlike traditional ducts Coolsox collapse easily when inflated which allows you to flatten them to maximise limited floor & crawl space. Simply roll out, cut and use in your grow space.
