OK, I think I answered my own question...I think I should use the simple distillation, because the fractional column is only for liquids that have a closer boiling point. Is that correct?

Then I am wondering about the condenser. I know I run cold water bottom to top, but can I use cold tap water? I have quite cold well water. Or I have the little vacuum chiller...or a laundry tub I could fill with ice water and circulate with a fish tank pump.

Yeah this was probably the wrong set to buy...I doubt I'll ever use the fractional column.
Ok, the simple dist set up will allow around 75-85% EtOH; if you want it purer (higher %) then run it fractional. Your cold well water is fine for cooling. Also realize there is an art to fractional distillation, most if not all your control is adjusting heating temp and the cooling temp; the principle is you want to concentrate the EtOH in the upper column before it goes out the condenser so that once it hits the condensor it's at high concentration.. In simple terms you want it to keep cycling for awhile in the upper column as it gets a higher concentration

I'm confused. Just to make sure we are on the same page here, I am attempting to separate EtOH from cannabis oils/resins. I guess I am still not really understanding the fractional column, and will read up more on it.

Only the pure strong alcohol stays in gas form. The rest gets condensed on the walls and drops back down.

Anytime I see light green new growth I think a lack of iron, could be many things though.
Yes, it's only in new growth so my best bet is to get them into some new soil probably! There is something they don't like!!

I just transplanted the last of my clones from the cloner, and done with that for a while. I think I am only going to keep a few moms going for the summer and plant a few clones outdoors....and I have a bunch to give away.
