Okay, my friend Douglass has 2 teks going. And he has 1 smelly fridge. Luckily, everything still tastes good.
So,this first pic is from Doug's lime tek, this is his 3rd pull, which he let naphtha sit for like 3 days.
Let it freeze for 2 days, this is what Doug has.
Good? It's a lot better than his first 2 pulls from it (90ml/90gram of mhrb):

NEXT is Doug's Cyb salt tek... It's greenish yellow. Normal-ish? This has been in the freezer for 2 days, he pulled it out yesterday and looked at both teks, then clumps started breaking off the bottom of this one.
Here look, green and what not.

Dangit Douglass, what have you done now...
So he did some researching, and found smelly freezers are common. Some people use dry ice in a cooler, but that seems like a bit much.
Can he put the plastic lid over these glass trays? Or will the naphtha react poorly to the lids? What about cling wrap? Or basic syran wrap?
He also read that you can freeze it in mason jars or whatever, with the lid. But he's was wondering how you'd get the crystals out? With a spoon?
He's looking for any advice he can get, because it seems this information is missing from both Teks, and he's a bit lost reading posts about what other people did.
Any advice is welcome!
