Picking the Proper Flower to Press

When pressing rosin from cannabis flower, it’s important to remember you get out of it what you put into it, like anything in life. Your source material is supremely important in determining the quality and enjoyability of your end product. As a general rule of thumb, when it comes to quality yields - good in, good out holds true. You can’t expect to get top shelf flower rosin from inferior quality or dry flower.


Whether you’re shopping for flower at the dispensary, getting it from a delivery service, or growing it yourself at home, there are a few simple things you can do to ensure optimal conditions for pressing rosin from your cannabis flower.


Shopping for flower at the dispensary can be a daunting process, especially in the era of regulated legalization where access to touching and smelling the cannabis is limited. For the purposes of pressing, we’re looking for maximum trichome crystals. The stickiest of the sticky, if you will. The more icy little bubbles you see on the exterior of your flower, the better. Those crystals are the oil that will be squeezed off of the plant matter and onto your parchment paper. Gorilla Glue #4 and other frosty strains perform quite well when pressed, but it’s not a perfect science. If a strain has been sitting around a while, many of those crystals may have been shaken off and sitting in the bottom of whatever jar it calls home.


It can be even more difficult to obtain the best flower for pressing when you’re shopping through your phone and relying on a delivery service for your source material. But deliveries still offer some of the most enticing deals on flower (and many still don’t tax) so they’re still a viable option. Most delivery dispatchers will text you photos of the flower you’re inquiring about, if product shots aren’t already available on their website or social media. One pro tip I recommend utilizing is asking your delivery service which strains are fresh and brand new this week, which ones seem abundant in trichome count, etc. Shoot, you might even get lucky and get someone who knows about rosin pressing and can point you in the direction of the highest yielder, never know. Never hurts to ask questions, worst they can say is “I don’t know” and you look elsewhere.


If you’re growing flower at home, the final stages of your harvest are vital to the viability of your flower as ammo for your hard press. Moisture is the enemy, as you don’t want any water mixed in with your oil after pressing. Allowing your plant to fully dry out and cure is key, both to obtaining the best flower and ensuring any nutrients or chemicals used in growing are flushed out. Don’t worry, those crystals won’t dry out, they’ll be there waiting for you. After curing, avoid overhandling and any other activities that will shake the crystals off your plant material until your ready to press. Using humidity packs like Boveda can help maintain optimal freshness in your flower storage container.


No matter how you obtain your source material, it’s so important to know what you’re looking for. Nothing is more disappointing than loading up on flower, just to press it for disappointing yields, and then you can’t even smoke it, either. The hunt for great flower is part of the whole enjoyable experience. Once you’ve shopped around a bit and enjoyed a number of your favorite strains that press well, you’ll be hooked! Shop smart, and remember to pick the stickiest.
