I just wanted to show you some ytong nests I made yesterday. Pictures are bad because they were taken with my iphone. They look much better in person. I know nests look very wet. It is because I was doing some tests about how often do I have to water them. It looks like once a day is enough. Nests have small water tank on top where I add water. Tunnels are 1-2 Cm deep. They will be housing my small L.niger colonies. Size is 6x4. It took my around 20 minutes for each nest and it costed 6$ total (frames were 3$ each and I had ytong blocks at home). It was a real fun making them and I will make few more when I buy more frames. They are not nearly as good as professional ones like mordam's but I like them. If you have any suggestions or critics please say. Thanks!
