EC or PPM Meter
Hi everyone,
I'm into my second attempt at Hydroponics. This time I did more research and hopefully produce better quality vegetables.
My Questions:
Do I really need a meter to test the EC or PPM of my solution?
This is my setup:
NFT (lettuce and tomatoes)
15 gal reservoir
Maxigro and Maxibloom
PH 5.5 - 6
After I add my Maxigro to my reservoir, I test the PH and it's about 5.5/6.0
I guess I'm fortunate that I don't need to mess with the PH
I realize it has nothing to do with EC or PPM but is it really a necessity?
If so, which one...EC or PPM?
What brand is recommended?
Thank You for you help,
HH
