Looking for Affordable EC and pH Auto Controllers

Hello everyone,

I'm looking to purchase automatic EC and pH controllers for my grow setup, but most options seem to be quite expensive. Does anyone have recommendations for reliable yet affordable automatic controllers? I'm on a tight budget and would greatly appreciate any suggestions or feedback on where to find the best deals.

Thanks in advance!

What you want is not cheap. If you DIY it you're looking at about 300-400 USD for pH control. But need to programm your own microcontroller.
If you don't want to do that or require more reliability you're looking at 4 digit prices or more.

I don't understand what you mean with EC control? Do you have any idea how different ions are taken up by plants?
