Hi guys, first time grower getting close to harvest.
On a scale of 1-100, I enjoy a stone level of about 1-10, usually one hit twice a day – once or twice a week.
So with a 2×2 harvest coming soon I am thinking how to get max shelf life. Taste in such small doses isnt much concern. Im like the last person who would think about concentrates…

3 months agoAsk a Grow Question 3 months agoDoes 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.

Structure is a major factor when determining how to grow a plant. First a few terms. The top growth on a branch/stem is called the meristem. The upper most dominant meristem on a plant is called the apical meristem. At the extreme ends you’ll have a plant that looks like a x-mas tree with a fast growing apical top with short side branches or…

I used de on my outdoor plants this year on August 11th right before flower because of the terrible amount of aphids I had on one plant that turned out to be a male anyway. Long story short it rained and rained rained here a ton and washed it all off but if it didn’t, my plan was to wash them August 13 with a garden hose and soaker nozzle.… Read more
