I wouldn't use those sensors in that relay configuration. it will for sure overwater the plants. Also, those probes are sensitive to corrosion and will become useless in months, causing more overwatering after some time passes, and continouss overwatering when they go out cause of corrosion.
I used that kind of sensors to water plants, but with the help of an arduino uno and extensive code including lots of software and hardware fail-safes. It will work, but you still need to change probes every 3-6 months for good results.
Decided to go analog first and complicate the hobby later.
Would this be a good pot for 1-10v dimming of a hlg driver?

And what's the difference with the ohm value? I've heard 100k for one driver, and 50 and lower for more drivers?
Thanks in advance.

I got these and they work great. The angled connection points made them very easy to mount in a project box. And they do actually have a 6mm dia. post.
I skipped the resistor. My light maintains 10% output with the pots turned down to 0.
