Note: Someone in an RV group recommended that I post this here,
complementing your NG for having many great ideas.
We travel pretty regularly in our RV, and have recently bought a winter home
in AZ. When we're away for up to two months, our house plants (in WA)
somehow survive, with a good soaking when we leave, along with placing them
so they'll get enough light, but not burn up. They're awfully thirsty by
the time we come home.
Now that we expect to be gone for longer periods, we need some kind of
automatic, indoor watering system. We need to shut off our house water
while we're gone, to avoid potential disaster, since our house is somewhat
remote. In other words, whatever we get will need to be battery operated
(winter power outages are common) and draw water from buckets/tank/whatever.
So far, what I've found doesn't have enough capacity to do the job. We
too many plants, which will suck up a lot of water in three to five months.
It's not practical to have someone go to our house, nor do we want to impose
that on anyone, especially when they wouldn't have water to use for
themselves (not to mention our complicated alarm system).
Does anyone here use an automatic system, or have a brainstorm for how we
could keep these poor plants happy? Some of them are decades old... we'd
hate to do them in. Thanks for your input.
