    @Mondy ,

    nice recycling job with those bags.

    I asked this of @psychonaut so getting a second opinion, in case these would work. I have some small hemp fiber
    teabags for raw tea. I like the idea of them being hemp. They are similar to a coffee filter material , but a "coarser" filter.
    Has anyone ever tried them ?
    psychonaut thought they'd retain some rosin so not good idea. They don't appear to be strong but not sure how much material strength it takes ?? Wish they would work---no press yet so I can't test yet

    Nice honey rosin there dude! :drool: Beautiful color at those temps too. Any idea how fresh those cookies were?

    People debating whether plant waxes cause lipid pneumonia, meanwhile it makes my rosin shine like a set of 20" inch rims! Such a nose on this one!

    The flowers are around 5 weeks old I believe.

    Not sure if that was me you spoke with on these unless I was too high to remember! But I do agree with the theory. Seeing how hemp fiber behaves as a filter for WT stems and such, it will likely hold onto some oil but it is absolutely worth a shot. There's really nothing to lose and everything to gain by experimenting. As far as I know all the filters hang onto something.

    For smaller quantity though no bag is needed, you can just go straight into the press and use a needle or something to pick out any plant matter before you collect.

    RosinTech is the real deal. I spent time with them at the Vegas Champs show and they have the whole spectrum covered---from small presses to big boys.
    They did sample presses that were very im-press-sive. And their reps were very knowledgeable.

    They also seemed very customer focused and responsive as one of their small units is being upgraded very quickly to V.2 with a couple small improvements. They seem to support feedback/improving their lineup.
    Their presses made some primo rosin at the show.
    PM me if you need more info/have questions.

    The one question I have is how do we make our own rolling "touthpaste" unit? :D

    i am all for experiments but i strongly believe that these will probably rip apart and if they do not, they will act like a sponge and hold much of your rosin in them. :2c:

    I understand why you like the material, i myself don t feel too safe with the nylon bags / screens many people use. I prefer to not care about some plant matter, i mean we even consume whole flower...
    You could look for SS screens / bags...

    The tooth paste rosin technique does not work...I think it were the people from @verdamper tried it once and showed videos of it

    Gr33nSanta over on IC was repressing unfiltered flower rosin through coffee filtres (10-30u) at 83C (180F-ish) and noticed the rosin, while tasty, didn't get him high. The cake of residue tested high for THC (a crude test that converts THCa into a THC reading).

    I have not seen another repost similar result, his technique is not widely used.

    That's how they make the solventless sauce. Repressing rosin multiple times over a few different temperature ranges will leave behind THCa in the filter.

    Yes but at a much lower temperature.

    Edit: Ah nevermind. Last I read of the solventless THCa they were pressing closer to 60C. I am out of the loop.


    The results I have seen from that SHO roller don't leave one with the desire to fork over the equivalent cost of far better performing units available. They peddle expensive bags and a variety of relabled Chinese machines. Their slogan would be offensive if it wasn't an apt description of an industry heavily populated with bandwagoneers flipping cheap imports.

    My mentor in this industry, whose knowledge of rosin is skin deep, had no trouble talking circles around the rep with information he picks up in our conversations.

    As a lark he gave him a flower sample of a cultivar I know well, as they were pressing on site. He achieved half the yield.

    I have to wonder if his payment for the event was eclipsed by the value of the oily pucks he collected.


    Might be wise to quickly wash tea bags in alcohol.

    According to what I've seen and read, any filter is going to retain some rosin. That's why I decided not to use one until the wee flecks o' green in my beautiful rosin started to bug me. And as far as lost rosin is concerned, I'm saving the spent pucks and will throw them in some alcohol someday to recover what's left (and I don't think it's insignificant).
    I like the idea of hemp bags too. It seems to me like the question is are they strong enough not to rupture?
    Now I'm just impatiently waiting for my White Widow to give me enough flowers to try some larger scale extractions! :)

    I compared the T-Sac hemp filter to Reynolds parchment paper and parchment seems to tear somewhat easy like the tea filters.
    When I try a "push a thumb thru it" test, the parchment takes more push to pop!

    EDIT---time will tell if the T-Sacs will work for pressing ( maybe not so well) BUT they will work for after the pressing and keeping the puck herbage out of coconut oil, while infusing it for edibles.

    Is popcorn worth pressing?

    I would say yes, but the yields will likely be around half what you see with colas, at least IME. Also if the popcorn buds are not very matured you'll get usually a racy euphoric high which is nice if you dont have any of that in your stash.

    I exclusively press popcorn. Yield varies 12-25ish%. Varies on cultivar, growth, method, etc.

    Tend to find smalls have a sweeter smell and produce a lighter extract. Less developed than the colas in a sometimes better, sometimes worse way.

    For my last squish I broke the colas down into small nuggets thinking the increased surface area of exposed resin might allow for better performance. Not sure if there's anything to it, I was just thinking about bubble hash where it seems like exposed surface area has a lot to do with yields.

    Saw a post on Reddit of a dude who claimed pressing flower in 37 micron bags results in less waxes and lipids in the rosin. I'm kind of skeptical cause I wonder how do you get the oil out without melting the wax membrane surrounding it? Curious though if anyone here also extracts with these finer bags for flower rosin?

    I saw it too and believe I posted my skepticism as well. The wax is melted, no filter is going to stop it unless it's a sub 20u paper filter. IMO of course, I have not done any valid tests.

    Seems like an easy DIY test if anyone has refuse from winterization kicking about.

    A quick google and wiki generically puts plant waxes as melting at 40C/104F, further increasing sketicism.

    I use coffee filters for flower, roughly 20-30u. I notice various consistencies from sappy messes to spreadable to waxy taffy budders. I would put cultivar, flower quality and extraction method as theories before filter type.

    Just an update on another test I ran just for fun with my bench vice plus hair straightener heating plates rig:
    I bought a gram of "Fucking Incredible" that says 27% THC on the label.
    I squeezed two quarter grams and then all the rest, and squeezed them all three times.
    2 min at 240 F (after 210 F was a dud--maybe it just wasn't all the way warmed up yet?)
    Yield was about 1/10 gram of nice sticky goo, but considering that the label said that it has 32.49% total cannabinoids, that's not a very good yield.
    I'll soak the spent pucks in alcohol, so I should get all the goodness eventually, but I was hoping for more.

    was it properly re-hydrated to roughly 62% relative humidity?
