I HAVE AN 8 SITE 10 GALLON reservior dwc system this is my first hydro grow and i wanted to know is it really needed to have an ec meter

Hey there. Im running a 20gal DWC myself and sucessfully completed a grow without an ec meter. HOWEVER, since i decided to to drop the cash on a good meter my plants have exploded. Having the ability to know exactly what your plants are uptaking and how fast they are doing it is very valuable info in our quest.

I have also found that having a constant reading on EC and Ph allows me to avoid quite so many res changes. Before i used an EC meter i would do everything by proportions and this required fairly frequent dumping and remixing/refilling of the res so i could know exactly how many nutrients (PPM) i was allowing my plants to eat.

SO all in all, its TOTALLY possible to get by without one but i believe the investment will pay off 100 fold in both quality and yield... not to mention peace of mind.

Hope that helps.
