Nope, that's the basis of the Hempy Bucket. A small reservoir at the bottom to sustain your plant for a few days longer than if they were watered with drainage at the bottom of the container. It's a mini built in res, and gets used up before it has a chance to go bad.
When I last grew I watered them until the bottom was full and water started coming out the drainage hole. An extremely small amount of runoff, if any. I'm not sure if this is how everyone does it, but I did it like that, with pure perlite on the bottom 2" and then pure fine coco for the rest, and didn't have any issues with the plants.
Hempy, I'm curious why the rectangular trough space saver method with 4 plants isn't used instead of the round pots. This guy put the hole 3/4th of an inch up rather than 2 inches.
