Hey @anon62804309! Here’s a post I did about the Kitty Cat Cloner.
I really like the cat litter pails. They’re small, easy to move around, and the lids fit them tight, so they don’t drip. They’re 12" deep, and 9 1/2" wide, so you could fit 3 of them in a 2x2 for sure. The way I size the standpipe, mine holds about 2 1/2 gallons. If you double up on your clones, you’re looking at 72 per run.
Oh yeah, that’s a 550GPH pump, it’s $15-$20 bucks at Amazon.
Building a small aero-cloner isn’t very expensive, and it’s easy to do. For me, the key to success is that Permaclone process. I’d used aero-cloners in the past with single digit success rates. Since I found their site, I’m in the high 90s.
I don’t know that anyone ever will, but if you’re reading this, and you decide to build one, post a picture somewhere, and tag me. I’d love to see how it works out. 
Have a great day everyone.
