The Reservoir
The reservoir was made from a Sterilite 5 Gallon square container. Many people have said that square is better than round, well after seeing these babies I can see why. They are mush smaller than a 5 Gal round "paint" bucket, yet hold the same amount of fluid. That is a 6" ruler next to the container.
I took a 4 1/4" (108 mm) hole saw and put four holes in it, but you could do what ever you want to up here. .
I chose this configuration just because It was real easy to put four grow cups in each corner with a pump in the middle pumping straight up like a fountain. I suppose if you wanted to use a setup like this for clones, then you would probably be better off making a bunch of smaller holes. I prefer taking them out of here then placing them in the veg room using the same container
