I am in the process of building an orchidarium to house mini Angs and Pleuros. I've always been intrigued by the Pleurothallid Alliance, but we just get way too hot to grow them outdoors here. I have a few already that are being housed in a temporary tank that I've already outgrown. I plan to use a 10 gallon tank (too small I know but its all I can fit right now) flipped on its side using a vertical conversion kit designed for arboreal treefrogs or thumbnail darts. I'm doing a vert tank because everything in it will be mounted and that't how it will fit on my rack. I'll put a layer of LECA on the bottom for some humidity control. I'm using a computer fan that I'll place in the center of the bottom (raised off the LECA) blowing up. The vert kit will also have a small area of mesh for gas exchange. I'm using an ultrasonic cool mist humidifier that I've placed two pieces of tubing into the output and siliconed the rest of the output closed. I plan to feed these tubes through the mesh on both sides of the tank. My main question with this whole setup is how often should I spray the tank (if at all) and how often should the plants be taken out and actually watered thoroughly. I would assume a good watering (soaking) once a week, but I'd like to know people's experiences and what they do. P.S. the title is for mrbreeze because I know he grows almost entirely in tanks and I'm growing similar species.
