Hope you had a joyous holiday season.

I have been using the system on a few house plants. Seems to be working very well. Now my wife would like me to build beds inside for organic plants to use. So I would love to get some help my friend.

Here is what I need. I will start off,with filling storage tanks. I plan to have a Rodi system(our water is bad). This will feed into a large container ,controlled by a mechanical float valve. Then that will be pumped (when needed) into another large container, Then be pumped to the irrigation system per the automation and watering system . In that container, I want to mix the fertilizer in.

So I need a circuit to tell the pump that the second tank needs water.(using float switches.) After the second tank has been filled I would like to put the fertilizer in, controlled by a flow meter. The flow meter will be connected to a pump in a container of liquid fertilizer. I will have a small pump turn on from a second relay in the watering section, about 10 mins before the beds are watered.

Any help would be great. I used to program many years ago. Wish I knew this language.

Thank you in advance.
