Is EC the preferred way?
If you can pick up one of these bad boys youre golden. Best purchase ive made yet other than my Hanna pH pen.
Mine will be here tomorrow
Can’t wait to be more confident in my solution
Thanks for everyone’s contributions to this topic. I’m really glad to see the scaling explained and it confirms some things I have observed and worked out on my own. The biggest takeaway here I think is that spending a little more money on a reliable EC meter rather cheapie tds would better serve the beginner growers if armed with the knowledge to convert to either scale properly.
