its going to be my first hydro grow pretty soon. im doing a switch from soil to ebb flow buckets with a 55 gal. res. i was just wondering if someone could tell me what ph/ec meter is good for this setup. i want a meter that i can just drop the probes in and get a constant reading. also want a brand i can trust that any hydro store will have replacement probes if needed. i seen some hanna's out there but dont want to get those cause i heard they do a different conversion on the ec readings in the US. please help with a model and name of it, much apreciated guys.
