Must use vac?

[Anton Cherniavski]

Can you actually achieve a decent quality shatter without a vac pump?
I mean low heat purging,like this guy over here,you can see that @5:00 he gets that shit really nice and clear...and than he just overcooks it:

No. You must use a vacuum oven and purge for at least 3 days.

Also distill your butane before using and use a closed loop system with gas traps. And have gas traps set up on your vacuum oven as well.

Are you saying 3 days minimum on any amount your vacuuming? Or is this strictly for large amounts? I generally yield around 4-7 grams at a time.

If you winterize after blasting, a vacuum is not a must.

How ever long it takes to remove all solvents. You would have to do trial and error. Get it tested each time to know how many ppm's you have. If you only pull that much. Then you should make rosin instead. Spending $15,000 on equipment isn't worth it for that small of yield.

You shouldn't be making bho without all that equipment either.

Yes it does. You still need to remove the solvents. Winterizing is just a poor mans dewaxing.

I know you love to tell everyone who asks about bho to spend a fortune or not bother. We get it, everyone really should do as you and make nothing but solventless from only organicly grown buds hand watered by naked virgins. But that wasn't the question.

The question was is a vacuum chamber a must. And the correct answer is no, it is not. It is very possible to purge the butane without pulling a vacuum.

When you perform a "poor mans dewaxing", (again, really?) all of the butane will be purged while the ethanol is still liquid. Purge the ethanol with a fan and some gentle heat. No vacuum necessary.

Plenty of questions with no answers like this.
There has to be a way to do it as there's many places that have oil and it's illegal still for marijuana.

Keep telling yourself thats. When your contaminant tests come back with high ppm's for several different solvents then you'll know why.

or just bust out the everclear and make some qwet with flower and booze at -18f broke my arylic lid so no bho for me right now lol.

 

[MedicalMike420]

I will give you my personal opinion on this. This is how I learned how to make BHO, shortly after I started to have "air-trapping" in my lungs. I never had a doctor or anything actual link the two together but I personally believe the two are linked.
I switched to N-Butane only and got myself a vacuum chamber and never did that half ass ghetto shit again.
If you don't have the money to get something to remove those harmful gasses then don't risk it. a simple chamber for small batches doesn't cost much. I purge for 3+ days.

In the beginning there was no data, so we best guessed and experimented, until we reached where we are today. Part of reaching where we are today was the introduction of Gas Chromatographs into our "ghetto" processes, to see how we were doing, and the results were an eyeopener.

Ergo we found far higher residual solvents, than previously predicted based of human sensory thresholds for odor and taste.

In national concentrate competitions, not all of the samples failed, but surprisingly more than expected, even though each entrant was convinced enough that he had the winning concentrate, to plunk down high entry fees to enter.

Attached are the FDA standards for residual solvents by classification, but local standards are typically significantly more stringent.

What happened as a result of those failures, and the publicity it drew, is that there was a general migration toward vacuum technology, which makes it faster and easier to remove residual solvents.
