Awesome. To me, this is a very cool take on live resin. I don't think a lot of people realize how volatile the terps are, like for example even drying your buds for the normal 7-10 days then blasting them you're going to lose a lot of the original characteristics.

My main point though was that if anything might be unsafe I would think it to be smoking the concentrated terpenes that you extract as they are, cannabis derived or not. Anyone who has worked with concentrated terpenes knows that some of those chemicals are crazy strong solvents! I would agree though that if you are diluting them by adding only a small amount to your product, mimicking the ratios found in nature, then the consumer should have nothing to worry about. Its the extracts we see today with crazy high terpene content that I worry about.. a lot of the time it burns the hell out of my sinuses or throat.

And thanks! I'm going to try and stop lurking and jump into discussions more. I very much appreciate this communities' passion for sharing knowledge

Hey Prime. I am very far from an expert, but I have been picking up quite a bit, both from reading and performing my own experiments. I think that heat can be a bad thing for terpenes, but IMHO it is actually heat plus oxygen and/or heat plus water (and certainly heat plus high pressure) that can cause adverse chemical reactions. These reactions don't happen (much?) in a vacuum with nitrogen backfill even with higher levels of heat. It is tricky because even with nitrogen at higher temp levels (greater than 100C), if you allow too much water vapor to form in your volatilization area, which for me is my vacuum oven, than you are in effect steaming the material in the oven, which drenches it with water and creates that dry hay smell. If you allow oxygen into your volatilization area, at higher temps you will get terps that smell like the wet sauna at the gym.

Lot of testing needs to done on the safety limits of inhalation versus orally consuming terpenes at different levels. My point about the ratio was really to draw a comparison to smoking or vaping huge quantities of flowers everyday. People that smoke 4-5 grams of flowers are consuming the same amount of terpenes and thc as 1ml of vape oil with 5%-10% terpenes, except without all the other inactive ingredient that get smoked as well.

I certainly would not recommend spending the money, and honestly I seriously doubt the efficiency of these units, but it will give you an idea how others are trying to make commercial products. These use steam, which will require a different approach to collect cannabinoids, to volatilize terpenes.

Virtually everything is available here for a small fraction of the cost - https://stores.ebay.com/deschemsciencesupply/ However, I have to be honest that the Lab Society injection port (https://labsociety.com/lab-equipment...ion-port-tube/) looks like something that I would love to have.

The ln2 method is fun as hell, but honestly not super practical. It uses about 2L-3L of ln2 per pound (wet weight) of fresh flowers and takes perfect timing from when you cut the plants for peak ripeness.

I will be trying my terpene extraction with cured material that is frozen to -70C using some of the methods below, but I will just freeze flowers in pot for 6-8 hours and then do all same steps of ln2 process (but without the ln2) with stainless sieve set. I want to duplicate the methodology using only dry ice and not ln2. I really think that fresh flowers need ln2 to be effectively processed this way.

Now that I have all the True Terpene stuff, I am going to do a new round of analytical testing. I am going to place a glass container with 10ml of TT terpenes in my oven and watch the volatization as I raise temps. This will also let me test the efficiency of my condensers and cold traps and really see what is getting collected and where. It will also let me test my separation techniques. I could also do a separate test where I freeze the terpene mixtures at different temperatures and see if I can observe sublimation. More soon...

I am curious about the use of THC-A vs THC for vape pens as it pertains to chemical reactions and internal seals (ie leaking cartridges). Is the acid part of THC-A more aggressive than distillate or decarbed shatter? I understand that terpenes can cause reactions but was wondering about cannabinoids as well.
