Opinions on cheap substrate moisture / EC sensors (Teros alternatives)

Hi,

I’m interested in getting a sensor similar to Teros 12 or Acclima TDR. Currently, I’m going to use them only for spot checking and increasing my understanding but in the future I might try some simple irrigation automation with it.

I’m using 100% coco in 1 gal pots.

I can find cheap TDR sensors on AliExpress (can post link if it’s allowed) that go up to 8 in 1 - temperature, moisture, EC, pH, NPK levels.

I assume NPK and pH sensors will be crap but I mainly need moisture/EC readings. Does anyone have experience with those and are they at all close to a high-quality sensor like Teros 12? Do I have any other relatively cheap but reliable alternatives?

Thanks

Cool idea, I like that bore hole installation tool as well.
Any idea about pricing?

Cheers

This seems to be the one many are buying

I’ve also looked at BlueLab Pulse but the review I read about it are unconvincing.
