Yes, Johnny, I put drain-holes in the paper cups and set them in a plastic tray with water in the tray, not watering from the top.
Yes, Johnny, I'm not using water directly out of the faucet - I'm using faucet water after it goes through a PUR water filter and it's a new filter. I haven't collected rainwater but I think the plants won't know the difference between filtered and rain - I'm not telling them.
