I did mine with a hole saw. 2" bit and added as many as I could fit in the bucket. Surprised that all the soil stayed put. Air pots rock but they are sort a notch when in tight places. Seems like they always get hung up on each other
whoa man 2" sounds big. I also thought about holes of that size so I have a question: if I were to drill holes that big, would it be recommended to put mosquito net on the bottom so the soil stays put and drainage is still possible?
