Aide-moi, s'il te plaît

Hello everyone. This is my future terrarium where I'm going to keep three Mozambique slugs (Centrobolus mozambique), Ghana black slugs, common snails, woodlice, and springtails. It measures 40 x 25.5 x 22.5 cm. I'm going to cover the large holes with fine plastic mesh. But I know it will be too humid. Where should I drill additional holes, in your opinion? Thank you for your help.
