I think I'm typing too much, but I also apologize if I'm being thick headed...
Why don't people post their individual EC's in their recipes? E.G. I run 12.5 ml (per two gallons) of GH Armour SI, which equals (if i recall correctly) 90 ppm or so. GH & RO = 500 scale, so that is an EC of approximately .18 However, I never see recipes given out that way. For example:
Step 1. 2 gallons RO water
Step 2. GH Armour SI to .18 EC
Step 3. GH Micro to 1.6 EC
I don't ever see the above. I'll see it in ml, or ppm.
See this? "If you are reading from a book that says you should grow your crop at 1100ppm - how do you know which scale the writer is referring to?"
That is the question you are answering. I understand that.
What I'm saying is, I don't ever see anyone post the recipes in anything except ppm or ml. They might give you a total...say an EC of 1.8, but they don't break the ingredients down in EC...
So, if EC is a better standard (I agree that it is) why aren't people posting that as the unit measure for the individual parts of the nute recipe?
The question might not have an answer...or the answer might be, "That's just how it's always been done."
I'm just curious what you think about that question...if it seems like I'm hassling you, that's not my intention. I'm genuinely curious...
Here is what I mean...
At about 1:25 (& throughout the video) they tell you what they are running the EC at. That doesn't give me any info except the total ppm. (If I knew what scale they were on, I see that point) They tell you the NPK ratio they run at various stages, & total EC. However, that isn't the full story of what they are giving that plant for nutes.
Maybe that is the answer, people just don't want to give out their recipes...
