I'd like to know how many and of what sized hole to drill in the side for air. I figured maybe use a .25" bit to drill a hole every 6", all the way around and up and down the bin.
Secondly, would it be a good idea to get some pvc pipe and drill holes in it, adding two or three of these through the center of the bin, to get air into the middle of the bin, since it's so thick.
Lastly, I'd like to collect the worm water, for watering the garden. As you can see in the picture, it has a plug, but this might be too high and allow too much water to sit in the bottom. I was thinking of raising the bin up on logs, drilling 3-4 holes in the bottom inside the diameter of a 5 gal bucket, and sticking that underneath to catch the liquid. This might let a little water be on the bottom, but the excess should flow out and the rest should wick throughout the bin so I don't have to wet it as often. Does this sound like a good plan for the drain holes?
