What humidity should I target?

Roughly 65-70% for seedlings, 55-60% in veg, 45-50% in flower, and 55-60% with low temps while drying.

Do I need one in a small tent?

If your room already sits below 55% RH in flower, no. If you are in a humid climate or a basement, it is the cheapest insurance against losing a harvest.

Bud rot does not announce itself. It starts inside a dense cola at high humidity and you only find it when you break the bud open at harvest.

This 30-pint unit pulls the room down to a safe 45-50% RH through flower and stays quiet enough to live in a spare bedroom or basement.

Auto shut-off at your target humidity and a continuous drain option mean you are not emptying a tank every day.
