Hell yeah they help! Im jealous I wish I had a soil tester. But the tds sensor can tell you the PPM of your water after nutrients are added so you can make sure it’s not too hot. Like right now im running 550 to 600 ppm per gallon for early flower. The other tester will tell you how wet the soil is and other things but cant see from the pictures

The TDS & EC meter can be helpful when using liquid nutrients. The soil probes can also be helpful but probably shouldn't be relied upon exclusively. I use my pH meter frequently for testing both soil and water.

You’ll have to look up the parameters for herb. The meters will tell you the numbers. Then you make sure those are within the parameters of what you are growing/stage of feeding.
