I have a spare pump just in case, but I did get a quick lesson lol. Hempy was great, my only problem was the info I found said to drill the hole about 2 1/2" from the bottom. I did that, but it doesn't leave enough of a res and they dried out a couple of times. That left less than a gallon in the bottom and they were drinking a lot more than that. I would make the hole about half way up
