And did it make any difference?

Couldn't agree more with @farscaper on hydration. I experimented with varying moisture's and it is much better with hydrated flower. I've even done the dunk in distilled h2o, let it sit a few minutes, then press as well as other hydrating techs...all good...all delicious.

this was my first press. 1/2 ton arbor press.

i've made a couple of the quick clamp presses. i call it an HMK rosin press cause hashmasta kut posted a pic of his and i immediately copied it lol.

thirdeyevision had the sweet idea to melt the plates into the pads on the clamp for a really pro look.

someone tell me if i'm posting too much for a newb.

No you're fine, keep posting lol. I was just wondering about the dripper because I have the same one and have had the same thoughts of making some sort of portable quartz banger type thing haha. I've noticed that on my quartz banger my rosin leaves more residue than dewaxed BHO, which makes sense. It's also the reason that I don't like to inhale the last 15-20% of the dab, because the taste goes from amazing to not very good pretty quickly and it kinda sours the taste (and half the point IMO). Was just wondering what your experience with the residue thing on your coils was like. I've got mine on an IPV D2 but haven't tried it yet. Good to hear you're enjoying it.

Loving the thread at the moment! So much good info flowing through. My straightener arrived last week and I've had 3 small pressing sessions with it.

I'm getting the same yield as I was with butane which I'm stoked about, I haven't even started rehydrating my buds. Next week I'll get to dismantle the straightener and fix the heating plates (+insulation) to my clamp and hopefully increase my yield.

I'm finding the high a little different to bho as well. It's more like being really blazed on just flowers. Maybe I'm crazy? Either way I'm enjoying everything about rosin!

Thank you to all the people that are sharing their knowledge on the subject.

I can't wait to see the off the shelf options in a years time

So it would be advisable for me to thaw my fresh frozen trim and dry a bit before I press.?

try some fresh frozen and some thawed. report back on the frozen trim vs thawed and dried trim hypothesis.

is this fresh freeze? or has it been stored in a freezer for sublimation purposes (ie freezer cure)?

I was planning to use it all for bho and qwiso so I just froze it straight after harvest. Now iv decided I want to do rosin. But wondered if the excess moisture would ruin the product. Iv thawed some out and kept some frozen. I will do some runs later and post my results with pics.

The nice thing about rosin is you can simply squish a .2 and assess whether it's worth while. No need to invest a bunch just to find out it was a bad idea.

Right then, one more thing while I have your attention. Will the pressure of my hands be enough. Or would you advise I use a clamp similar the the Irwin one earlier on this thread.? I can create alot of pressure with my hands.

I'm about 230Lbs. I was getting about 10% back from my straightener at 290F-ish (analog). The flower quality as well as moisture content has the most to do with it IMO and then pressure and temp.

My clamp didn't last very long because I abused the weak heaters. When it was working, the same strain seemed on track to be 14+. But I couldn't even squish an entire gram at a time so I didn't get a good chance to asses. I'm going on vacation for two weeks starting tomorrow also so I won't be able to revisit my gear until December.

I'd say you can absolutely assess it by hand, but I'm not entirely sure it will approach economical without at least a clamp.

For me, economical was in the 14+ range.

Just make sure you squish a second and maybe third time, folding the chip onto itself once or twice in between presses. You'll definitely enhance your yield that way.

Higher pressure options generally eliminate third presses and sometimes second presses and just ensure the inevitable last bits of oil get out of the chip.

In my experience so far, my chips clearly have oil left in them... just not exerting enough force to do so. You may still profit even still though. Try a little and see. It's best to have a milligram scale to test a small bud and go from there.

Good luck.

Ok thanks for that. Trial and error tonight then. I will try with and without clamp on frozen and dry trim and cured cola bud.

You should be able to press by hand well enough to get a good idea IMO. Try holding the iron at the edge of a table, so you can grip the edge with your fingers and make a hand-clamp (use a hand towel or something, the iron gets HOT )

if it were me I would find a vice or clamp around the house or grab a cheapy and try with that for extra power. just stick the hair iron in the vice or clamp. most will hold up a while and are less prone to sliping when in a vice or clamp. but you can go native if you want too.

try re hydrating those chips and repress them again... you might find what you need is a little more steam to push the oils out.

to the general thread:
I think there is always going to be a limitation to how much pressure is necessary... only so much force can be used before damage to parchment occurs.... and as I have hypothesized earlier I think you have a combination of factors that play into rosin.

heat
pressure
moisture (or as I now think [steam])

the moisture is in deed the key element in moving the oil... or rather... extracting it from the plant material... like a solvent.

pressure is key for creating the most confined space possible inside the plant mass to prevent the rosin from soaking into the plant material once it has been liquefied by heat. if you do not apply enough pressure without enough moisture you will end up with rosin soaked chips.

So effectively the code we are trying to crack (if your someone trying to crack said code)

how much steam do you need? (perhaps a better way to say this is at what RH is the best extraction possible... or rather what RH at what temp under pressure produces the steam effect)

how much force is needed but limited to how much force parchment can handle at that rh?

some observations ive done...

very moist flowers spread way more than dry flowers do. no idea what rh was cause I dont have a hygrometer.

the burrito and other wraping techniques work great at containing steam during extraction with hydrated flowers. I note that when I release the vice when flow has decreased or ceased entirely there is always a steam puff when I unlock the clamp. very interesting stuff cause tge extract is the most flavorful ive had in a while from the same stock.

@farscaper

Have you considered adding a drop or two of water to (what will be) the closed end of the burrito, before closing it up?. My thinking is that it may be possible to improve yields and quality by creating more directional steam flow through the entire column of material.

I'm currently building self-heated pressing blocks, which will allow me to press burrito style. I'm excited to be able to work with this technique in the future. Thanks for sharing your thoughts and knowlege, it's much appreciated!

@farscaper, I have clamps and vices, I'm a carpenter so have these things to hand..

Has anyone used foil lined parchment paper. Will this work. Or will this just insulate from the heat source. Or will it just take a bit longer, but actually distribute the heat better in the end.

Any advice???

Freezing teim doesn't add any moisture or weight to bud. If anything itll be slightly drier after. (Used to store large amount in a freezer).

As for yield I think it effected it but I don't have scales anymore so couldn't really tell.

I found fresh trim too moist and left a wet product. I think we are coming to the consensus about 65%rh is ideal. Although this is still open to discussion and I am currently pressing almost bone dry trim and getting pretty good results

this is a good idea right here. effectively creating a steam chamber... and also confirms my suspensions if successful.

@kellya86 I dont use the foiled parchment and others have also found it to be inferior. key thing with parchment is "quilon free"

I'm still a little lost on this burrito thing. I tried a sort of burrito and it sort of worked. I didn't like the consistency so I went back to my original way. I wish there was a vid of how you fold the paper from start to finish.

I posted this pic 17 pages back, it was from a pretty fresh nug and if you look at the left side of the crease, you can see what I think is a water drop and what looks to me like oil/water mixed swirl.

I bring this up because yesterday I repeated this with another 4 day old nug and I got really good returns from it. I think yields increase with more moisture but I think the increase is mostly water. I can hear the oil/water sizzle when vaped. I assume the sizzle is water moisture anyways..

i have a couple on IG showing how i do it. @sunfire_ranch coined the term burrito tech.

this is how i used to do it for my early model HMK press (quick clamp).

here's how i do it with t-sac brand paper tea bags and fold for my shop press (2"x3" steel bricks).

i did that envelope a bit too tight you can see it blows out a little. i recommend leaving a 1/4" of space for expansion.

regarding fresh frozen i agree it's got a lot of water in it. you can dry it and smoke what's left behind but the yields are low and flavor is not great.



if i want live resin terps i get great results pressing 2--3 days after chop. there's still a decent amount of moisture left inside so it takes a bit of finesse with the press. i ususally lower it and do a gentle press for a few seconds, then proceed to full force. that helps prevent blowouts in my experince.

OMG WARNING: that reminds me don't put your face anywhere near the pressing area when you press fresh frozen! blow outs explode out with a lot of force and sticky hot oil gets everywhere!

these were squooshed a couple days after harvest. if you've got enough force, it seems to be a good way to get insta-budder. most strains i've pressed in the shop press this way come out as budder. the first pic is done with the HMK press so no budder





since the question was regarding ff already in the freezer, i'd do IWE (bubble hash) and rosin any of the hash that's not full melt.

Perhaps this confirms why quicker, higher heat squashes seem to lead to clearer more shatter like rosin, and slower, lower heat squashes seem to lead to milky, less translucent, more sappy rosin. There is more water moisture in the lower heat squash result so it's an emulsion of sorts and less 'pure'.

**EDIT: assuming both starting materials were equally hydrated

All this talk about re-hydrating your pressed chips , sounds good .
I'm gonna try some tonight using your Iron Hidea .

I will try using the steam button on my Iron for pressing
my shirts , and see if that will give it a more even spray .

Here is a video of .75g being squished @215f

Haven't been in this thread for a while but that is incredible! Vice press is definitely still front and centre in my mind, I CBF manually pressing flowers lol

Grabbed this from the Rosin Facebook group, gives some insight into the effect of pressure and heat on the bud:
