• Does anyone else use this EC pen from Apera, EC20? If so, how are you converting to PPM since it doesn’t specifically display PPM? I’m finding a ton of mixed answers on how to convert the readings.

      There are two scales used: multiply by 500 or by 700 (depending on where in the world you are, US typically uses 1EC = 500ppm). So EC 1.2 = 600ppm on that scale (840ppm on the 700 scale). Because of the two different scales, generally you should avoid thinking in PPMs and just use EC.

      • Why do you want to convert it? Reminds me of trying to convert C to F temps constantly in my head living in Canada. Really I just need to understand C….lol I relate more to PPM than EC also though

      • PPM/TDS meters have a US or UK scale. US scale is 500 while UK scale is 700. Those scales are programed in to PPM/TDS meters based on EC. 50 ppm is 0.1 EC on US scale. 0.2 EC = 100 ppm, 1 EC = 500 ppm. 2 EC = 1000 ppm.

        • I knew about the 500 or 700 scale but this is the first time I’ve heard that it had to do with where on the planet you lived. This answers some other questions as well. Thank you

          • I use that same one for PH. I just have a simple cheap PPM/EC pen I use for the other.

          I’m seeing more and more Mephisto and their recent Oreoz drop seemed to be pretty popular. I’ve not really seen specific strains being grown more than others, it’s been pretty diverse and everyone is growing something different.

        • With each grow, each new plant…I feel I’m getting better. Probably gonna be my highest yielding plant so far. I’m proud of it anyways.

            • Would anyone by chance be able to recognize this spider? And if so, is it any danger to my plants? The best pic I could get of one before I accidentally scared it away. There’s usually a couple of them, sometimes one will be around a bud sites but usually they coccoon a fan leaf blade around themselves or be sandwiched between 2 blades.…

                What did you end up getting? I’m using Coco Loco right now and I’m liking it more than Happy Frog, so far. I’d like to do just Coc, just need to get some.
