Hi! I'm about to start using coco husk as my bedding (a combination of visuals, humidity and longevity as my motivators). I've heard the bricks are most economical, and I'm prepared for a steep learning curve of figuring out how much water needed to expand then without making them overly wet.

However, my main question; per standard 'brick' (~700g, where I've found them), how much surface does that cover? I have a 3 foot viv - though buying more won't go to waste in the future, I'm just curious as to how large they expand.
