Integra Boost is ideal for maintaining moisture and preserving the aroma and flavour of fresh harvest. Optimum moisture is important at all stages of cultivation, as too much moisture can cause mould and not enough can result in dry produce. The produce then decays, looks bad and, of course, tastes bad. The Integra Boost system is used to control humidity in confined spaces. Using patented technology, it can release or absorb moisture to keep it at the ideal level. Safe, 100% salt-free and 100% non-toxic. Integra Boost includes an intelligent indicator card that alerts you with its blue color when it's time to change for a new pack. All Integra Boost products are FDA approved. They are 100% salt-free so they will not alter the taste of herbs, fruits or cigars. They are tear and spill resistant, biodegradable and non-toxic.
