pH meter is by the far most important so make sure yours is accurate. do you calibrate it? keep it b/t 5.5 and 6.1 always.i do not have a meter for ppms etc. how essential is it i get one of those?
i use about a $30 EC meter. EC meter is also important: i like to see my EC dropping slightly every day to prove they are eating nutes.
