Hey Dinkle. What Magoo said. Throw the hygro in the main part of the fridge. How much bud will you have/How many plants? When you put them in fridge rh should shoot up. I'm using a dorm fridge and took me a few days to dial it in. First it was too high so turned temp up and rh went down to 16 so turned temp back up and found sweet spot. Can you adjust temp? Don't give up yet. Low and slow rules!
