Moisture Sensor Automatic Watering
Does anyone know of a house-plant watering system that uses a moisture
sensor to water plants via an electronic valve? None of the "automatic" watering systems out there work. They all seem to be either passive wick or timer-based systems that keep the soil so moist that root rot always occurs. What I'd like to see is a Thirsty Light moisture sensor (http:// www.thirstylight.com/) cobbled together with the Orbit electronic watering kit (http://www.orbitonline.com/products/Timers/ 01/04/01/1195/). The trick will be interfacing the sensor with the watering kit. The watering kit is actually meant for outdoor use, but it looks like the cheapest source of electronic water valves. |

Never heard of this, but it should work. All you need is soil moisture senors, some electronics, and some electrical-controlled valves. Sounds a little expensive, plus nature doesn't work that way. |

Since apparently no one's ever thought of doing this, there's also a certain element of novelty. |

I use a reservoir (water dish below the plant ), the plant supported above the reservoir and a acrylic yarn wick from the reservoir into the bottom of the plant to draw the water up into the plant as needed. There are several sites on the web which discuss this (Google wick watering). Again the key is acrylic yarn for the wick and soaking the wick before inserting into the bottom of the plant. I use a reservoir big enough so that is holds several weeks of water so I can go on vacation with out worrying about the plants. Dana |

Dana All those kind of systems are watering the potting soil, not the plant... they generally over water and drown the plant by eliminating air. Most potted plants need far less water than we think, and most do best with alternating periods of drought. When a house plant is in a properly sized pot in proper soil for that particular plant then there is no reason if a plant is watered before departing for vacation it can't go a month or more. If one is particualrly concerned over some finicky plants then it's best to have a responsible person check on your plants like once a week. Watering potted plants is a lot like feeding aquarium fish, both can go a very long time between. People who set up those automatic fish feeders typically come home to dead fish and a stinking mess. |
