Small pump in the range of ml

Hardware

Hello Arduino community,

The idea is to make an automatic watering system for my plants. For this, I want to have different fertilizers which mix together using a magnetic stirrer, using an Arudino Nano IoT (or multiple Arduinos) controlling the pumps. However, I can only find pumps with a passage of around 600l/h. I think this would be a little overkill except for the water tank, so I want to ask the community if anyone knows any suitable pumps for this project so that I can mix different fertilizers in the range of 1-5ml in a relation to around 1l of water. I would mix the fertilizers in a separate tank with a magnet stirrer and then add the plain water and mix them with another magnetic stirrer.
Does anyone have recommendations for suitable pumps?

Thanks in advance!

Edit: German and English answer are welcomed <3!

You might end up looking at some kind of 'dosing' pump... Here is a couple of links from Amazon... some of these are stepper and some are just 12/24/120V....

Good luck...

Do consider a failure of any of your pumps a reason to stop the system? How will detect a failure?

I was thinking of using flow meters to check if any water or fertilizers are pumped through the pipes at all, but maybe I will just check on the pumps every now and then. But that's a good objection I should give a little thought to. :slight_smile:
