I recall reading about putting it in the fridge overnight in the original thread? Could be wrong, but what surprised me was how much faster the crystals grew when the EA was still fridge cold when salted with citric so I do it now as part of the tek. I find no issues with condensation, and a lot of droplets seem attached to the walls and bottom of the glass after decanting. Never been a problem and now I *always* do the overnight in the fridge just for the speedy crystal growth.

When I use fumaric acid I have a hard time getting crystals that way though but that's another topic!

I have seen it cloud up when in the fridge for a bit, but assumed that was filtered out when decanting through a filter because it cleared up after that? Not sure, but it was never a problem. My only issue was once letting some 'sludge' from the french press phase get into the filter (and a bunch went through it seems). This appeared to precipitate out with the mesc (mostly crystals but with a solid layer of white on bottom), but I cleaned it up by adding it all to the next extraction powder.

The lab grade is monohydrate, but I have used supermarket version too (its finer than the lab citric) - but results in the same predictable behaviour.

I am using distilled.
