I use this unit now and absolutely love it! Takes water temps too which can be important for hydro growers. Has to be calibrated often. But keeps me on my toes.

i had a bit of a problem, too much water, rotted the stems of 2 plants, so a friend cloned them for me and put them into coco coir soil in pots. so looks like i might ditch the ebb and flow system.

is it still as important to check TDS and is it the same meter?
whats the difference between these 2? any good?
