I appreciate your concerns. I tend to keep a low profile. You have to living here and growing weed.
The number one rule to live by when growing in a non legal state is: Don't be an asshole. Be a good neighbor.

I transfered the contents to a small round bottom flask in preparation for the distillation step. Looks like my shortpath distillation head will be here saturday. Then the next step can begin.

I don't know much about the short path method and am not planning on trying it anytime soon.could you explain the advantage of this method rather than a simple distallation under vacuum?

The advantage is for when you have high boiling points that you are trying to distill. The short path doesn't give the product time to solidify before reaching the receiving flask.
For example. The waxes and resins in cannabis are solid well above room temperature and in a normal distillation setup, they can clog the condenser and not even reach the receiving flask.
In addition to all of that, there will always be some mechanical losses when distilling. Some sticks to the sides of the condenser and distillation neck. The short path minimizes losses in that regard so that when working with small volumes like this, you don't lose as much product.

ok,I think I'm following.bare with me,like I said,I'm green on all this.so if I am following along correctly,youre distilling your extract over into a clean flask?

Correct

once you hit different bps you just switch out flasks?
btw,I agree with your wax/extract prices.east coast here (not the easiest place to find extracts where I am) prices are from $30( I personally would not smoke) to $50.the $50 is strain specific.supposedly

Yea that is the idea. The boiling point will remain constant until almost all of that compound comes over, once the bp starts to rise, that is your cue to switch out receiving flasks.
It will be worth it if like last grow where I got 3.2 oz of trim to convert that into extract. If I can really get 50/gram. That is a nice boost in profits.

Very cool.thanks for the lesson.look forward to your finished product!

I am still waiting on my shortpath distillation head..... USPS tracking says it's scheduled to be delivered on the 18th still. Stupid out dated mail system anyway. Hopefully it will show up soon so that I can begin the next phase.

How about this idea? Rectangular glass baking dish with a condenser consisting of a finned aluminum heat sink of the same shape and size with fans on it. You fix a sheet of parchment to the flat side of the heat sink, put it over the baking dish with an insulating gasket and clips, and put the dish on an electric griddle. That would be the shortest path ever. You put a thin layer of weed in it. If it was an airtight gasket you could put a vacuum hose attachment on the heat sink.

An interesting idea. The problem is that I will need to be able to pull a vacuum in order to perform the distillation. The boiling points of THC and other cannabinoids is >315°F at atmospheric pressure, which will severely degrade the wanted product. Here is an image of a shortpath distillation head so that you have a better idea of what it does.
Here is the setup with all attachments.
As you can see it is a closed system. The 3 nipples on this are used for cooling and pulling a vacuum. The first 2 are for optional water cooling or even heating. The last nipple is used to pull the vacuum needed for high boiling compounds.

How will you prevent bumping?

I will use 4mm glass beads. Though I may not need to since I will have a stir bar in there as well.

I'll be looking for a new pump over the next few months to be able to do vac distillations.right now I'm trying to figure out what to do about the bumping.I have a stir bar option but I'm not sure how well that will work once the extract thickens up

Your best bet is to use broken glass pieces, or you can even buy boiling stones from most laboratory supply websites.
