Integra Boost Humidity Indicating Cards - 10-60% RH - 10 Count

Check Storage Humidity at a Glance - 10 Indicator Cards

Harvested plant material can degrade when humidity inside a container drifts out of range, and you cannot see that happen. These humidity indicating cards give you a visual reading of relative humidity from 10% to 60%, so you can confirm storage conditions without opening a meter or guessing. Place a card inside the container and read it when you check on your stock.

This unit holds 10 cards, enough to monitor several jars or storage containers at once. Hobby growers can keep one in each jar, and small commercial operations can use them to verify packaging conditions across a product line.
