A poster postulates that ether is particularly good to grab water soluble terps from water. (Which seems like a better choice anyway for lle except it needs to be dried after extraction and distilled before use).
I have also a litle question, hopefully someone would like to answer:
Whilst performing a wash, is there a danger that under particular circumstances thca or cbda could migrate to the water? We all know it does at very basic ph with NaOH but could it also happen otherwise with certain acids or bases?
