I’ve grown indoor tower gardens in Florida for years, but my daughter loves cucumbers and tomatoes, which need outdoor pollination. Towers aren’t practical for big plants, so I designed a simple, portable system using a 5‑gallon bucket. Instead of sprayers, I used a cascading flow like my tower garden. Water pumps up, feeds all three pots, and drains back down. Maintenance is easy—just lift the lid and move it to a fresh bucket.
