Ah ha! I was wondering why part B of front row ag developed a "wet" texture to it. I wasn't sure what was causing it to be hygroscopic. Once I put it in an air tight tote, it seemed to stop pulling moisture. Luckily it didn't get rock hard or anything, but it certainly picked up some moisture while living in the original bag.
Do you follow manufacturer recommendations for making concentrated solutions or do you throw n parts salts into h parts water, then determine the volume you need to use from that concentration? If the latter, have you noticed any issues with more water soluble varieties hitting a field capacity (maximum concentrated level by volume) at a certain ratio?
I spoke with front row ag, asking how I could make concentrates and the numbers they said to use for salts-per-gallon seemed way too high. Something like 880 grams part A to one gallon and 900 grams part B to one gallon. What are your thoughts?
Like you, I'm sick of dumping little bits of salts here and there whenever I weigh out, which is weekly and soon to be every few days. Having a liquid concentrate would be much more time and resource efficient.
