Simplest Q: Will an amount of water applied to the *edge/rim* of a
potted plant have the same distribution in the soil as applied to the
center* of the pot?
Why I ask: I'm building an indoor potted plant watering system.
Basically a water tank --> pond pump --> four dual (fridge ice maker)
solenoid valves --> t-connectors --> plants. All that plus the lights
are under computer control. (Been using CP290 for years just for the
lights but have recently upgraded to CM15A and the nicenice X10.com
So I have 8 'channels' of watering schedule, but certainly not enough
individual lines, so the t-connectors supply more plants. I find that
due to -siphoning- (when not delivering water) and low delivery
pressure (when delivering water) the -ends- of all the t-connected
lines must be at almost -exactly- the same height. Roughly within a
(1/4") hose diameter of each other, probably some hydrostatic physice
going on there but I ain't a physicist so this is all just from
observation and conjecture. :)
Mounting the hoses -reliably- at the -edge- of a pot is easy, but
aiming for the -center- is fairly difficult both at initial setup and
given likely minor movement of the lines in the future.
BTW using the tank and not mains because I'm on the 4th floor of an apt
bldg and if SOMTHING GOES WRONG I need to limit my liability.
I'm 99% done, down to installing the lines which is where I'm finding
this siphoning effect. Will have pics and a web page about it when it's
done. Here're a couple of pics of what's there now, a bit of an indoor
jungle :) http://www.jbarchuk.com/img/plants/plants053104-1s.jpg
200k a pop so beware.
Thanks much. Have a :) day!
