PSA FOR NEW PRESSERS. RE-POSTING from my profile. Been a while and we have a lot of new guys in the sub.
Getting Started
BEFORE YOU MAKE ROSIN:
Quality in – Quality out - - - This can NOT be over stated when dealing with any type of rosin. Starting material is everything, especially in the world of flower rosin. If you have quality, you may get good yields. I repeat…may get good yields. THC-A or CBD-A does NOT equate rosin yield.
Rehydration: There are many choices when it comes to getting flower ready for the press. Moisture levels between 58% and upwards of 78% are generally accepted as ranges for pressing. As this is my site and I am giving the advice, I will tell you I personally prefer 62% to 65%. Boveda & Integra Boost are two of the main brands for rehydration. I have a personal experiment posted (Link) for reference. Natural means to achieve the same are fresh greens from the produce department. Place the green (spinach for example) in a plastic bowl with the flower and leave to sit 8-12 hours depending on preference.
Notes: This can NOT be overstated. This is rule number 1 for PRESSING! In the notes you start with a base line for every strain. Any – AND I DO MEAN ANY – TIME you press something new, its not the same as the last time you pressed that strain. Someone else grew that plant. The grower from the last grow quit. The soil producer messed up a delivery and the nutes got messed up for two days. ITS NEVER THE SAME! This means NOTES.
If you take a base line with every strain, you then have a way to see what your flower will give you on a rosin scale instead of looking at the THC or CBD content percentage like a gauge on how much rosin you will see in the jar. THC-A / CBD-A % DOES NOT EQUAL ROSIN OUTPUT.
The base line:
Pick your time – temp – bag or no – pressure …. I use 190 – 90 – no – 700
So every new press of a flower…I advise doing the following.
Flower X Pressed @ 190F for 90 Seconds @ 700 PSI = RosinYield or RY
Next… looks like this
Flower GSC Pressed @ 190F for 90 Seconds @ 700 PSI = 0.50
Flower GG#4 Pressed @ 190F for 90 Seconds @ 700 PSI = 0.65
Flower Tropicana Cookies Pressed @ 190F for 90 Seconds @ 700 PSI = 0.73
Flower Green Crack Pressed @ 190F for 90 Seconds @ 700 PSI = 0.48
NOW WE HAVE DATA
So given my notes… I would say on the green crack press I would go UP on my temp to gain yield. On my Trop Cookies, I could go down in TEMP and increase the length of time under psi for higher quality and same yield. This is how you learn to manipulate the settings to maximize what you want out of your meds. Keeping these notes and having a base line to refer to constantly is the tried and true method of improvement.
Low Temp vs High Temp (Generally speaking)
Low Temp: 199’F Down – higher terps, flavor, taste, lighter color, more budder consistency. Tend to be lower yields.
High Temp: 200’F Up – Same terps mostly – Color slightly darker at times, more shatter or taffy like consistency. Higher Yields, slightly lower quality.
With a base line of information you can see where to adjust your temps. This is unique to each individual so I have not posted mine though many of my notes are posted for use. If you need to get the most then higher temps are your way. If you prefer the taste and pure flavor all the flowers can offer in rosin form, then lower temps are for you. Either way, enjoy!
We will use this formula: PSI=Press Pressure ÷ Bag Size Area
So PSI= 7tons(aka 14,000) ÷ 2"×4" bag (aka 8)
14000 ÷ 8 = 1750psi
For a more complete source (https://gopurepressure.com/blogs/rosin-education/the-physics-behind-rosin-heat-pressure) see here
BEST GUESS optimal pressure range for pressing rosin is between 300 - 1000 psi, at the bag. Flower will be on the upper range at 600 - 1000 psi and kief or hash will be on the lower range between 300 and 800 psi. The platen size doesn’t factor into these numbers. If you have a 20 ton press and press a 2x9 bag you are getting 2500 psi at the bag. With a 2x3 bag you will get 7500 psi at the bag.
Sorry kids, ADDING PRESSURE is really never the answer.
To those with not pressure gauge on your equipment – there are add on options. However, know that if you feel where the sweet spot is for you meshing between blow out and quality, then you are fine where you are. If this is a home hobby you may not need a pressure gauge. If this is a medical purchase for regular use, then get one with a gauge for sure.
ROSIN PRESSING 101
Break down the plant material. Popcorn size or a bit bigger works best (IMO) but you want to mold it into a small circular shape. If you have a pre mold / pollen press, this is where to use it. This is done to reduce any plant particulates that may end up in your rosin as well as giving the round shape allowing more even expansion under pressure. (round shape expands better, less blow outs, more evenly distributed heat etc)
If using a rosin bag, place the plant material into the filter. We recommend nylon food-grade screens or a mesh bag. (This step is optional for flower, but necessary for hash or dry sift.)
Bags: Micron = u
Flower: 75u -to- 200u
Hash/Sift: 75u -to- 15u
Set the temperature on your press and let it heat up while you prepare the rest. I would start with low and work your way up. Get your timer ready…
Place your PARCHMENT paper in the press and use magnets to hold in place. You want enough paper to cover both sides and front and back with hang over. Rosin will run away so just enough paper to cover the bag or flower wont be enough. If using a bag, I recommend using bottle technique to achieve a better yield but also this helps with the puck shape for small presses. (LINK) Place bag or loose flower between two pieces of parchment paper. Center it up and start the timer. Depending on temp now you pick your warm up and press times.
Bring the plates together to meet only minimal resistance on the press. This is to allow the puck to warm up. Let this sit depending on temp for 10 seconds -to- 60 seconds.
Start adding pressure (if there is a gauge monitor to max psi) SLOWLY. We want the rosin to flow out of the bag, not force it out along with plant matter. Let it flow. Bring up the pressure slowly. This should ~one third of the total pressure time. For a 3 min press, take at least 30 – 45 seconds to bring up pressure to max on a 3.5g squish. Faster, the bag blows or you force in contaminates. Slower, the rosin may set up in the bag. The rosin should flow so if that flow stops, its now cooking and curing into budder. Keep the flow going by taking the time to get to full pressure and let it sit flowing away for the remaining time.
Times up – Drop the plates and get the paper off the heat. Fine, take the picture but be quick already… We know you need it for the Instagram and reddit post but the rosin is cooking yo!
After removing the flower from the parchment paper, check the amount of Rosin. Again, notes are recommended. Personally if I press an ounce over 6 presses, I would keep the yield of each separately as would I keep those times, temps etc…
Once you have pressed your product, use a dabber to collect the rosin. Any dab tool or glass tool works great. Collect and put in an air tight space. Glass jars work the best, but parchment in baggies works as well. Once air tight please put your rosin in the fridge.
Storage: Refrigerate – room temp is ok but fridge is the best! Do Not Freeze, this does nothing but degrade the rosin with freezer burn.

If you didn't make the rosin...don't post it here. This is a make it yourself sub for home hashers and pressure. Please leave the dispensary drops on another sub.
Please report these posts so we can get them removed.
Thank you!

Hey! Would love some input on this post I made about the best o2.
Thank you :)
r/Rosin2 • u/710mmjik • 2d ago
Hashtek dropped a limited run of their 10 gallon washers. I think they are a bit steep in price but I have heard many professionals swear by their equipment so I ultimately purchased one. I have been looking to add automation into the workflow so I can comfortably do runs myself and heard mixed things about upgrading my other vessel so I settled on this. Hope to get several years out of it. Curious if others are interested by this too.
They sent it out to their email list but if you missed it here is the link: https://hashtek.ca/product/bubbletek-10-gallon/

Bred by the bro Inhouse Genetics. Grown, hunted, and pressed by me.
r/Rosin2 • u/Bairdc82 • 9d ago
From seed to press. 8x 3.5g pucks double bagged 37u. 28 grams of fresh dried and cured bud around 52-54% humidity. Got 3.6 grams in return which is a 12.86% return. Using a Rositek 2 ton press 3x3 at 180 degrees. The last pic is fresh after the first whipping. ✌️
r/Rosin2 • u/interplanetaryspace • 11d ago
90-159u

Hi guys trying to find the best press to turn dust into resin ? Thanks for you help
r/Rosin2 • u/ProfessionCurrent198 • 15d ago
Let me know what you think! It’s the second time I’ve made live rosin
r/Rosin2 • u/Competitive-Pass2035 • 16d ago
This one is much more Chem D forward. Fantastic flavor and affects.
r/Rosin2 • u/getsstabbedforfun • 19d ago
Got my hands on some cheap permanent marker, not the freshest but still yielded really well, and cured up really nice. Pressed at 77°c for about 3:30 total. Near 5g return from an oz which im super happy with.
r/Rosin2 • u/Maleficent-Freak-93 • 19d ago
Genuinely got 36 bucks and some change into it… pids and heaters carts coming Monday🤘🏻 made my own for less then 100 kinda proud😅 hope to be pressing again soon🥰

Pressed 19 grams of flower, resulting in a 10% return on flower press through 37u bags. The final result is 1.9g of flower rosin. Not bad not bad. I'm happy I picked up another pack of these seeds from 808 genetics :) time to wash an entire plant in the future 🫡
r/Rosin2 • u/TicosTreehouse • 23d ago
I’m new to pressing but I want to make sure I get a quality product that won’t kill my wallet I already grow at home and need to buy stock up on a few years worth of seeds before things change.
r/Rosin2 • u/trapjezusog • 25d ago
All reshares or reposts highly appreciated
r/Rosin2 • u/Bobduncan0604 • 27d ago
I recently got some extra credit to spend on Amazon, my budget is about $200-$300, do any of yall have any recommendations for any solid rosin presses I could get on amazon? They have a lot of options but I don’t wanna make a purchase I’ll regret. Any and all help is welcomed, thanks. (I’d prefer something that could press at least 7gs of flower/material).
r/Rosin2 • u/TicosTreehouse • 28d ago
Any advice is helpful
r/Rosin2 • u/Timely-Amount-5304 • Jun 21 '26
hey so i’m very very new to pressing rosin, am currently waiting for my bags to come in online but was wondering if there are any good options to atleast get my first batch going, ive tried looking for 120 micron tea bags but aren’t having too much luck with any unfilled ones
r/Rosin2 • u/n-bathroom • Jun 21 '26
Just started pressing with a hand press but barely anything is coming out. I pressed at 220 and 275, what should I do?
r/Rosin2 • u/Bairdc82 • Jun 20 '26
First pic is 14 hours curing after whipping. Second picture is this morning after whipping. This GMO papaya smell has very high terp levels that I just want to jump into 😅 I'm about to do my first test dab 😎 I just wanted to share this cuz I'm quite proud of my first test wash and press. Seems pretty successful so I'll be making more plants strictly for washing and pressing.
