I've started growing seedlings in a seedling tray which is a 6x4
array
of connected seedling pots. Each seedling pot has apertures in
its
base. The seedling tray sits in a water catch tray so water and
mud
don't get on the floor. The seedlings need to be watered every
few
days. I'm going
on 2 weeks holiday in a few months and I'm
thinking
of making a self-watering device.
My idea is to sit the seedling tray on a sheet of foam with holes
aligned with the apertures in the pots. The seedling tray will
then
be able to float in the water catch tray (with the foam sheet
and
the bottom few millimetres of each seedling pot submerged).
Thus
the
bottom few millimetres of soil will be sodden but the rest of
the
soil will remain moist.

My grandfather used to use a strip of cheesecloth as a
"capillary siphon" from a bucket of water for his tomatoes.
Let us know how this turns out (I suspect it will be good). |

Neat. My old man is talking about building a seedling table which suspends trays of seedlings on a level waterproof table with a lip. A simple float valve refills the table as the water wicks up or evaporates and it just needs to be checked on periodically. If you have an elevated water tank then gravity does all the work. |

Could network camera them and have a number of a friend as a failsafe. |

I don't know if this applies only to specific plant species, specific soil types, or what, but, at least in some cases,
continuous watering can be harmful in that it allows the roots to rot, and so intermittent watering is preferred,
because it allows the roots to dry out, which prevents rotting. |
|

Yep, this is probably not a great long term solution. This will
just keep the seedlings alive over 2 weeks of summer. |

Yes, really good idea [+] |

Every time I see the title, I read it as “Floating
Point Pot” |

Full-baking, nice!
I was thinking of how to do this "long term". Perhaps a very
shallow water tray, so evaporation & plant up-take can
change the level noticeably, but slowly. A (float or other
lever) valve attached refills, with a delay (a series of tanks,
so takes time to fill each one before the water gets to the
plant tray..?). |

I keep seeing this as "floating point pot", which then brings
to mind "integer pot", which is a whole
other thing. |
