    I also typically change the water in the reservoir once a year (seriously, but it rarely gets over 18ppm)
    However, i have to add to the reservoir pretty often (couple weeks maybe?)

    edit: after eight yrs the design is still identical to what it was day one, I am also a big believer in the benefits of high saturated oxygen levels so i keep an airstone running in the reservoir 24/7.
    That kind of maintenance isn't bad at all!

    I'm curious about the airstone. Wouldn't the plant roots get all the oxygen they need from the air that is forced into the soil as the water drains out? Does running the airstone 24/7 have any advantages ove running it for 30-60 min before flooding the plants?

    It is my belief that the oxygen rich water more closely simulates rain water. The high oxygen levels should encourage happy roots but maybe even more importantly kill anaerobic bacteria that tend to initiate root rot

    Too many variables for me to say 60 minutes would or wouldn’t work as well. I just don’t know.

    Looking at @Grey Moss photos, most of his plants seem to be in larger "catchment" containers, so any overage or pot drips would be contained. My temporary system resemble's Av8tor1's in that the entire baker's shelf was surrounded by water-proof material (plastic), and (in my case) the shelf system sits with its feet inside a larger catchment area. Each shelf has pots sitting on plastic egg crate lighting diffuser so the plants aren't sitting directly on a wet surface, then plastic shelf liner to keep any excess water from dripping on the plants below, so:

    POTS
    egg crating
    shelf-liner
    metal shelf

    Any excess delivered water evaporates off of the shelf liner, or runs off the shelf liner (at the edges, not onto plants below) and ends up in the larger catchment area that the shelf sits in.

    My shelf is also like Av8or1's, in that I access the plants only from one side of the shelving, which is part of why my set-up was only used temporarily. All the tubing going to individual plants was along the front of the shelf, and made access to the plants very difficult. Great when I wasn't home, but kind of a pain when I got back from my trip and wanted access to the plants. I like to be able to pull the plants out occasionally to check on new growths, screen for pests, etc.

    Eventually I'd like to have an area that allows for both automated watering and easy access to plants - and am thankful for all the great ideas folks share on this forum. Inspiration to draw from!

    Let us know how your system shapes up!

    So many great ideas indeed!

    Madrone, thanks for describing your setup. The use of "catchment" containers is interesting. By the way, what water pump do you have?

    I'm unsure of where to get started with drip irrigation, but I ran into this relatively cheap drip irrigation system on amazon (see link). Has anyone used something similar?

    I purchased an Aquagarden fountain pump with auto shut-off. Since my first time using it was for a period when I was going to be gone, I didn't want to run the risk of the water reservoir running dry while I was absent and frying out my new pump. Depending on how many pots you are trying to water, you may opt for a higher or lower flow rate pump. It was probably overkill for my recent application, but was purchased imagining a larger scale application (some day) There is a bit to figure out with DIY drip irrigation, but it's do-able. A local hydroponics shop may be able to help you put together the pieces/parts.

    You also asked about the "ready-made" programmable versions - I have used one of those - not the exact one in your link, but something darn similar. Note that it's only appropriate for a VERY small number of pots - the pumping action is minuscule. So, it may be easy to quickly outgrow (depending on your plans for your plant collection). I liked the flexibility of the hosing that was provided (made it easy to get the dripper into tight spaces), but it smelled AWFUL when it arrived. Soaking and flushing seemed to help, but it was almost eye-watering out of the box.

    Following up on this thread, I plan on using the Mistking setup. The misting will keep humidity levels high and even though they are pricier it seems like they're considered the best in class and scale well to multiple setups. Also can run dry for some time!
