Re: Auto Dosing EI with a dosing pump (diagram and calculati

@ Another Will: I've been thinking along the same lines as you.

The control and reliability of using a medical infusion pump seems the way to go surely?

I agree, the precision of the medical pump seems ideal, and some over at APC (i think) are using one. I would have got one if I had not won the peristaltic pump I did!

If you are a bit handy, then try an Aspen Standard peristaltic pump used for removing condensate water from aircon units (Mine was £10 from ebay). Although it has a three minute run on time, it will be easy enough to change (but I do have a industrial automation background!) The units are solid heavy duty ones, designed to be built in to voids, and hardly touched, but run reliably run for years. I'll probably run mine via an arduino, to get specific amounts of fert dosed.
