Everything should be here and put together on Saturday, some parts arriving Friday. So either a trial run Saturday evening or Sunday. 
Dutchman's Rosin Room!
- Thread starter Dutchman1990
- Start date
Pump, press, and most of the other accessories have arrived. Just waiting on the gauge and the tee for it. 
Finally a test squish. 7g flower (super lemon haze) into 1.5g of the good stuff. Going to do more later.

Glad to see your resining it up now multi! Rosin is my favourite thing to smoke!Finally a test squish. 7g flower (super lemon haze) into 1.5g of the good stuff. Going to do more later.
Thanks Dutch! There’s a learning curve to figure out still. I must have been off a bit on my scale,’but I ended up with .7g, not 1.5g. Did a second batch with another 7g (this time with GSC) and got about .8g from that. So 10%, not 20%.
Temp was 185, and the puck came out flat AF.

If you back up to Dutchman 1990 videos I think on page 16 it tells how two week old curing weed will give more rosin in that period. I had some WW in the jar for six months or more that gave about 10% rosin and a week in the jar that gave 24% rosin made a believer out of me .Thanks Dutch!

Thanks. I’ll have to give that a try next harvest. Closest I have now is well into cure (4 weeks or more) so that’s the best I’ve got for now. I do have some temple balls, but dunno if I want to sacrifice those for this yet.
I’ll mess around this evening and see if I can come up with anything. I wonder if it’s a humidity issue.
I waited till it hit the 62% humidity in the jar . Took about a week .Thanks. I’ll have to give that a try next harvest. Closest I have now is well into cure (4 weeks or more) so that’s the best I’ve got for now. I do have some temple balls, but dunno if I want to sacrifice those for this yet.

The little digging I've done seems to recommend 60%-65%, with most saying the cure point at 62% (because of boveda packs, I'm guessing) is where it's at.
I don't cure in jars, but I do store some in jars that I want to save back for later. Of course there is a boveda pack and a hygrometer in each jar.
The flower I used was certainly in the neighborhood though, so I dunno. It may have been mid 50's, but shouldn't have been as it came from a jar with a pack and hygrometer. I don't recall the reading off it now, but it wasn't anything I batted an eye at either.
I do see a lot of "live" resin presses from fresh flower, but IIRC it's at least been dried a little bit.
Got a lot to learn with it, no doubt. I have a bag of trim/kief left from my Granddaddy purple. I'm going to get that into the right range (although it should be already) and see what I can do with it. Also have a couple oz of blue dream trim left, so may use that to play with as well.
The press comes with the quick connect coupling for the hose. Just take it to Princess Auto, or a hydraulic company and they can verify the size.
This is an awesome read alot of questions have been answeredDutchMans’ RosinTo make “rosin” the precious gold we all want is pretty simple and straight forward.
Room
What is it?
Well in the simplest of terms Rosin is an extraction process that takes a combination of heat and pressure to squeeze the resins from Weed.
The “rosin” is incredible in flavour and potency. It can be made with either the bud, trim, kief, or hash! The result is a translucent, sappy, and sometimes shatter-like product which has a high terpene profile and 0% impurities compared to a solvent extraction like BHO / Co2.
The Process
It combines heat and pressure! That’s it!
For all of my Pressing I have been using the 6-ton unit from DabPress. It’s an excellent quality product for the money and I would highly recommend it if your looking to get into your own pressing!
First let’s get into the basics of it all from:
-what equipment I’ll be using
-what size micron bags should be used
-times/temps for trim/bud OR kief/hash
-my own how to guide from bud to rosin
Equipment 
The DabPress unit is extremely easy to operate and a real pleasure to squeeze with. The anodized plates heat up quickly and hold the heat extremely well. The PID for unit is easy to operate with good functional controls and an accurate readout of the temperatures. 6ton jack allows for great pressure across the plates to easily squeeze up to 14g of your favourite bud!
Other than the unit itself all you will need is parchment paper, micron bags, and you guessed it weed!
Micron BagsNow Micron bags or filter bags are a special component to making sure the rosin stays clean of any plant matter. Different sized micron bags are used for specific product and each will return different yields and quality. Here is a reference chart to check and see what size bags work best.
Now I’ve been using 90u bags for pressing so far. I decided to choose the 90u bags for flower because it produces a higher quality end product allowing the least amount of fats and material out from buds but still giving you a decent yield! I’ve been using SupremeRosin bags and they are absolutely fantastic! They all come preflipped with the stitching inside (unlike other companies where you have to flip each bag before using it!) and also a card in each one which allows for easy filling!
If you dropped down to the next lower level of micron screen you will notice a significant drop off in yield. Increasing the size of the micron bag will result in a higher yield with little change in quality as long as you don’t get any blowouts.
I have used 90u bags for all my squeezes so far but I have just ordered some 160u bags for flower and 37u bags for my future hash Pressing! Interested to compare the results from a 90u to 160u bag! I’ll be sure to post.
Times and TempsI would encourage you to try your own temps and times as this is just a rough guide for you to follow from the research I’ve done.
Now let’s talk about temps and times for different products!
Kief/Hash
You want to Press kief or drysift at a lower temp than you would your buds or trim.
The temps on the lower end are between 160-200*F. These lower temps will produce a end rosin with more flavor/terpenes, less yield, and more stable like shatter consistency.
Trim/Buds
The temps on the higher end are between 180-220*F. These higher temps will produce an end rosin with less flavor/terpenes, more yield, and is less stable like sap or budder.
When pressing at a lower temp you will want to increase your time. The lower temps you can press your buds for up to 3minutes being the maximum you would want to press. The higher end of the temps you want to decrease that time such as 90sec for a 220*F press.
Pressing your keif or hash you want to keep your pressure much lower and stay in the low end of the temp ranges.
My Pressing GuideAlright! Now that we know the basics and what we need to press let me take you through my process to go from Bud to Rosin!
First I turn on my unit and allow the plates to start heating up! I select my micron bag and prepare it. Now there’s a few methods to prepare your bags to get ready for pressing. One is “flat” pressing your bags which is basically filling your bag evenly and then laying it flat to squeeze. Prepress forms are great but not necessarily needed! Once you have filled your bag you can proceed to squeeze.
The other method of packing your micron bag is called “Bottle Tech Style or BTS” as I will refer to it here! To setup your bag for a BTS Press you need to First tuck in the bottom corners and make them touch in the middle. Once they are tucked in begin filling your bag standing up. Press the buds down evenly into the bag making a good seated bottom with the folds of the bag underneath. Once your product is inside the bag cut the excess bag off leaving about 1/2” above the material. Fold the top of the bag over like a gift and size your bag to the press plates so it fits inside nicely. Once your plates are adjusted to the right size I add my parchment paper in and place the BTS bag between the plates.
Here’s the step by step of this process in pictures!
Once it’s centred and ready to be squeezed I begin applying pressure. I get the plates to just sand which the bag down a bit to allow the product to heat up evenly. After a few seconds I begin applying a slow constant pressure until I start seeing rosin producing and then I ramp up the pressure!
SLOWLY but consistently I maintain that higher pressure and the rosin will begin to flow. Based on your temps follow a time that you have set out and be sure to follow it! Once the rosin has stopped bubbling or flowing from between the plates it’s usually a good indication as well.
Remove the parchment and press bag from the plates. Open the parchment with the spent bag and buds and place it to the side for Edibles if you wish! Some people use a cold plate to make collection easier but once your ready to collect get your dab tool and begin. Once everything is collected together is it ready to be DABBED!!
For this example I’m using 4.5grams of some Purple Trainwreck pressed at 210*F for 2min in a 90u bag. The end result was .98grams which is a 21.77% return!
Here is a video of this press!
I hope my guide helps you on your journey to rosin pressing and I encourage you all to join me here with any questions you may have!
I would love to see some of your squeezes so feel free to share!
Enjoy!
Stay Medicated!
Finished rereading the first post. I'll find time to skim through here and Grandpa Tokin's thread. I think I'm going to try my first press tonight. Need to get my hands on a fair amount of good flower...
I recently harvested some testers from some plants and I also harvested a large amount from an outdoor plant. What is considered the absolute very best end product when it comes to rosin pressing? Making hash and then pressing the hash?!
How about with the flower if I am not going tk make hash. Just dry the flower enough to be ready to be placed into jars for a cure? I really would prefer to press some of my own flower versus going to the dispensary to buy enough to make me happy with a big drip of rosin.

Hey everyone! Been a while since I posted in the hash thread and ooh wee have I got some golden goodness to share with you all! I’ll be putting some pictures and stuff together this weekend to share! Don’t forgot your drool rags cause it’s going to get crazy!
Hey I just bought a press and your first demo was exactly what I was looking for the get better results. Really useful, thanks so much!
