Integra Boost 4g Humidiccant Bulk (No Overwrap) 62%

These 1,000 Boost 4g pouches are intended for maintaining humidity between 62% and 65% relative humidity. The Integra Boost Humidiccant uses patent-pending technology that releases or absorbs moisture, maintaining relative humidity in a contained environment at or about 62%. One of the easiest ways to tell if your humidity is correct is by using a hygrometer, which can be purchased at most major hydroponic stores.
