Hello,
Did you only check the forum or did you also check FAQ and WIKI?
For instance:
https://wiki.dmt-nexus.me/Category:Enhancement_TekI do not have enough experience yet to give you any practical info but I can tell you to never, ever throw anything away until you have your final/total yield... Suppose you haven't done enough pulls and have already discarded your basic solution, you won't be able to do additional pulls...
Naphtha (tvättbensin in Swedish, not the stuff that goes in cars) can be a good alternative to Heptane, just make sure it evaporates clean (some camping fuels could be fine, others have anti-rust agents, not good)...
I hope this helps...
