Heeh, it is much posible geckos are very willing to have a taste of orchid flowers. We'll see if honey drops elsewhere keep them interested enough or not. Well, who wouldn't like orchid flowers

. It shows only they are very sophisticated and like gourmet food.
For ventilation there's going to be one fan low blowing in and one on the top sucking out. I thought lower fan could be quite near "water fall" and UV- lamp there quite near also, then it would maybe rise the moist upwards.
