New extraction technique? Rosin tech?

Has anyone had rosin tested for harmful microbials?? I have seen a bit of the water hash/dry sift has been failing and I am curious how rosin fares.

i'd assume if i were to use shitty moldy product going in, i'd have bad nasties in my rosin.

grey fox---

the t-sacs come in several sizes. i've got the #2 size which is roughly 2.5" x 4" (not including top flap) when i turn it inside out. too big for my HMK style press, so i've been cutting them down.

actually since i'm still pressing flowers and trim i inevitably end up just folding what is basically a flat sheet of filter paper around the snake after i cut it down to size, so i'm not sure the sack is actually helping much for me in that sense, however, having the sack will probably be convenient when i start pressing sift and water hash.

i really like how it hasn't blown out so far. it's got the ability to stretch with the material to a certain extent.

the rosin is super clean. gorgeous.

Id also assume if nasty shitty moldy product is being used harmful microbials would be found however lots of the dry sift/water hash that people have had failing is made out of FIRE that you would never expect to fail. Still curious if anyone has any results instead of just assumptions.

I wonder what effect if any the heat would have on microbial presence...I would think the steam would be enough to sanitize, but that's obviously just a hunch.

That is crazy dry sift is testing for microbials. I mean it is "dry" sift. I guess if they are using fresh material without a good cure there would still be moisture present. Crazy

its more likely that ignorant or unscrupulous people are sifting material that had PM or even possibly Botrytis. Not the smartest thing but I dont see why they would fail the test otherwise.

Leave a plate out with some auger on it for a day, then innoculate, you'd be surprised what's just floating around in the air. How tight are they doing these tests...ppT?

I think with most IWE the problem is improper drying. I net EsterEssence could say a few things about this...

ya water hash i understand how the processing could create situations for microbial growth, but dry sift and rosin, that would probably be bad product going in.

that's still me making assumptions tho.

I am not really any expert on moldy product, i know if i see or smell anything bad i will not put it in my tumbler. I have heard stories about people with large greenhouses that get some botrytis removing the really bad spots and tumbling the rest. If i see it on my buds i throw it away. As Sunfire says leave a petri dish out in your house and see what grows...

Bubbleman has now put up his D-Nail 15x15 Rosin press, Hash Review.

Working 40g of 3 star bubble.

I was watching the review. Seemed to work well for pressing the bubble.
Only thing I see really being an annoyance is the gap between the two plates is very minimal so It may be hard to set up and press nugs. works well for slipping in screens of bubble and potentially a screen of nugs.
Can the top plate be removed easily enough to do set up?

Yeah the space between is small but one thing Bubbleman wasn't doing is rotating the top plate out of the way. Unless because the way the wires are ran you can't. Most those presses swing out though so you can easily access the plates.

Idk if that one does that or not but when they do its called a "shuttle" design. Write him a letter and tell him lol!
 
So I'm really fascinated by the idea of making rosin from bubble hash, but I keep going back to the idea that yields people saying they get are not represented in a way that makes sense to me?
Watching bubbleman he states that he gets anywhere between 35-55% yield of rosin when pressing bubble has (depending on quality of hash), but what is the yield from turning the cannabis into hash? Does anybody know what the average %yield of cannabis to bubble hash is? I just cant help to think that this is an extremely inefficient way to make hash oil, albeit a fairly simple one.

the returns may not be as good as they can be with other methods; but there is something to love about a premium hash oil made with only heat and pressure; or in the case of bubble hash as the starting material, also water.

the long term effects of regular bho consumption are largely unknown, as it's a new thing and independent research is pretty much blocked...that unknown aspect alone makes the difference in returns a variance that I'm personally comfortable with. not to say that people haven't evolved in extracts enough to eliminate residual butane etc...I just have my reservations personally; if I can say that without sounding like I resent bho, which I don't.

Thank you for sharing. This is kind of what I suspected. I guess a follow-up to that is this. In the opinion of ICMag contirbutors is rosin, whether pressed from cannabis or hash, something that commercial dispensaries should be carrying?

I love the idea of an extraction method that does not use solvents, but I feel like the people who want rosin find enjoyment from actually making it.

HPO gives you a better high than BHO. Definitely more visual and a better front end. Possibly longer lasting too. So a small decrease in yield is for sure worth it as i see it.
