If your humi is dry, you'll have a little trouble with the beads. The beads are great at maintaining a certain humidity, but they aren;t great at adding moisture into the environment. If the environment is dry (as I assume it is in Ontario in April), it can be tough to get back up to speed.

A couple options I can think of:

1. Soak the crap out of the beads, rewetting them every day or two. Be careful not to get your cigars wet (this is what I do, even though it's not the best solution)

2. Put a small container of distilled water (shot glass?) in your humidor. That'll give the environment a lot of water to use...
