Can i get those at a grocery store? Lol

5g is perfect w/o blowouts. Tried 7g and blew my first 3 bags.

I like these bags the most. Never had a blow out.

It doesn't specify the micron. From my searches, 25iu works best for keif

It says 35u

Ahh, I found 25iu to be the best for keif from people's imput. But 100/50.00 is a pretty awesome deal. I'm 25/45.00. Wish they had 25iu, and I not just reorder another set of baggies yesterday.

Just did a nice dab and don't want to work in the garden. Good job. Lol

Anyone recommend a clamp for max pressure without breaking my hair iron?

I have to practically jump on the think to get rosin out of cured bud.

Someone said to do dried but not cured bud? Anyone have success putting a drop of water on cured bud to get more rosin?

@genuity do you dry the trim first before pressing and how would i go about doing that? I dont want crumbled leaves in my rosin.

I earlier replied that I didn't think water would help, but I just found a post on another forum when searching about something else and it may help after all.

I took a .3 gram nug and carefully applied a few drops of water. This felt like a weeeeird thing to do, since I'm used to keeping my nugs the hell away from water! I was surprised by how hydrophobic the nug was, as the drops of water just sat there indefinitely on the surface. Then I realized that this shouldn't have surprised me; of course, it's a flower! Anyways…

I added mutliple drops to compensate for the fact that most of the water simply ran off of it, trying to get some small amount of moisture in there. I pressed it out in the hair straightener and WOW! Significantly improved yield, at least 2-3x just eyeballing. Tried it again in the tortilla maker. Boom, same deal.

It may be that the extra yield was mostly moisture though. Still worth a try. How to add the water? Steam it I guess, or use a spray bottle, since drops just run right off. Maybe put it in damp paper towel until it moistens up.

About the water possibly increasing yield, maybe it's because it makes the bud more flexible and therefore more compressible. The steam it makes may also help carry the terps out by steam distillation of a sort. Personally, I don't think terps are desirable to smoke, but apparently some people like them, or think they do. Probably placebo effect. If you look at some of the test results for rosin in analytical 360 you'll see that the THCA/THC is usually around 60-80% but terps are only about 4%. How is that small an amount of terp going to produce a noticeable effect? Terps aren't that potent, to my knowledge. They'd have to be 10-20 times as potent as THC, and that is very unlikely. They do make nice aroma though, if that's important to people. Good to have some in there for that I suppose.

I just went to analytical 360 to see how the terp content of rosin compares to that of BHO. Turns out that the BHO is usually 10-15% while rosin is about 4% as I mentioned. Clearly the heat is driving off about 2/3 of the terps, or else they just don't get extracted in the first place. So has anyone noticed a huge difference between the effects of the two? Should be a major difference if terps are that important to the effects.

Rosin process for cannabis = flash steam distllation

Water will increase yield but it will make rosin too sappy. So you have to let it sit and dry for a couple days before collecting.

If flowers are too dry. Place a leaf in the jar for half a day or use boveeda packs. I swear boveeda packs preserve terps when used from the beginning of curing. It's just anecdotal. One of these days I'll get some terpenes profile tests to compare.

Broveda packs ftmfw!!!!! 1 med pack goes into every half gal mason jar after I get the rh to 60%

General consensus = Boveda preserves terps and retains optimal moisture content for squeezing

Unfortunately nobody has done tests with different moisture levels to see how it effects the outcome, at least not that I've seen. Something else that might make moist bud press better is that if the vegetable matter, meaning everything aside from the trichs, is moist the resin can't get squeezed in there because oil can't mix with water, at least not well. So the resin may flow over the vegetation and out to the parchment instead of absorbing into it. It's like how you can extract fresh wet bud with a non polar solvent and not get chlorophyll.

I used to do that using toluene. I wouldn't recommend it btw because it's the smelliest solvent around, but I would put some in with wet bud in a glass measuring cup and use a cleaned glass bottle as a plunger to squeeze the solvent around through the bud to get the resin. The bud would flatten right down from the plunging but it got all the resin that way. Some juice would actually get squeezed out and would sink to the bottom and I would remove the upper solvent layer with a glass turkey baster, which are hard to find now but I got lucky at the time. Then I would add clean water to the collected solvent and shwish it around to "wash" the water solubles out, then collect it again and dry it. Worked perfect, amber resin. You have to wash your extracts. People don't do that with butane.

I don't coddle weed when I'm extracting it, I press the hell out of it to squeeze all the resin out. It takes very little solvent when you're pressing weed down into the bottom of a glass, because it gets much more compact. I gave it 3 leachings to get it all.

Having a better yield now with the table vise. 250 for 25 sec right now. I have slowly been dropping the temps and increasing pressure as I become more comfortable with the process.

From what I have noticed so far:

Lower temperature = easier to gather and a longer press.

More pressure = more yield

Pressure + heat is causing steam which is the sizzle we hear. I have been repeatedly pressing until I hear the steam flow slowdown.

Pressure seems to be the most important thing for yield followed by heat and time. I feel like the intense pressure and heat is causing the trich heads to break and be forcibly shot out of the center through steam.

More heat = less flavor and shatter like consistancy
Essex heat = more flavor, but a gooey consistancy

P^2 x t^3 = p^3 x t^2

Pressure and temperature have a direct correlation and can be compensated with each other.

All the steam should recondense on the parchment

At demontrich- I like your equal signs! Go equality!!

See now I have read it is the opposite. Hot makes goop and low temps make shatter.

Here's my slab at a 185* pressing, budders up
1st pic

Here's the same slab repressed at 210*
2nd pic. Kinda like pull n snap, almost shatter, but not quite. Another 5* would be more like shatter

Might be kinda hard to see in the pics. Look at the different sheen on the 2 slabs. Made from dry ice keif from a 160 bubble bag, then pressed in a 25 micron baggies on my 20ton.



Huge difference in texture, smell, flavor when vaped.

I just remembered bubbleman has reusable bags that are 30 micron. I've never used them before so I can't speak on them. I've been meaning to try them. I just completely forgot they exist. They're on his site freshheadies.com

Wish they had 25iu. Found its best for keif, only what I press minus the occasional flower I press for myself.
