I love indoor plants but I’m bad a keeping them alive. I once had a cactus that died from thirst. I purchased a few Aqua Bulbs, which has been great help in keeping the big plant watered enough for me to get around to taking care of it. However, I can’t use the Aqua Bulb on my smaller plant. Also, Aqua Bulbs break easily and refilling it with water is always a hassle. This motivated me to build an automated plant waterer. Let’s call it ThirstyPlant.
