I'm now looking at three 4-litre (140 fl oz) pickle jars, stolen
(why do i do this?!!!) from the pile of garbage back of a
sandwich shop.
The jars are rinsed and have lids. I plan to drop a bed of gravel
into them, then some sterilsed soil from my indoor compster, and
then some small cuttings to make jar gardens.
I've done this before with 1/2 gallon wine flagons.
I have an old aquarium pump, and it seems to me that I could rig
up a rather simple tubing mechanism that would pass air into the
gravel bed of the first jar, and from the top of the first jar
into the gravel bed of the second jar, then the third.
By controlling the amount of water in the first jar (or by having
a zero-th jar that holds just water and thus passes moisture-
laden air to the first jar) I can control the air humidty and/or
soil moisture content in each jar.
In addition, if the tube for each jar passes down into the gravel
bed of the next jar, I'll be aerating the soil as well.
                       Moist aerated soil.
                      Plants should love it.
I wait eagerly for your lucid comments ......
