If I read this correctly, you have no humidification source in the humi, is that correct? You definitely need to add that. The Boveda packs work pretty well. I have a small overflow 100 - 125 capacity humi and have three of the 69% Boveda packs and it is rock solid at 66-67%. Beads are supposed to work even better, but the Boveda packs may be a lower cost and are available right around the corner for me. Enjoy your humi! BTW... Nice looking start!
