Hash Oil

Is there any way to make hash oil without butane chemicals?

there is an alcohol way
search iso hash oil

Yes, but this has nothing to do with hydroponics.

hexane, butane, iso alcohol, and a dozen or so other nasty solvents that all evaporate off into nothingness when your done will make oil. whats your beef with butane? its one of the faster, easier, cleaner methods.
