Waterbol

I was skeptical about whether the cork would hold up, but after a month of daily use it’s still perfectly snug and the water level indicator is super handy. The glazed finish also wipes clean easily, which is a nice bonus.

The glazed terracotta finish makes these bulbs look really nice on my windowsill, and the cork top seals well enough to keep the water from evaporating too fast. I've been using one on my peace lily for two weeks and the soil stays consistently moist without me having to fuss with it daily.

The cork tops fit snugly, and the glazed terracotta actually looks pretty on my windowsill instead of an ugly plastic bottle. I filled one and it’s been slowly dripping water to my fern for two weeks without me having to refill it once.
