Over the last decade, we’ve seen an explosion in the legal concentrate market. While many people still enjoy flowers of their favourite legal herbs, more smokers are turning to concentrates. Concentrates offer you a more intense smoking experience, with no plant matter getting in the way of the taste and effect.
So, what are concentrates? Simply put, they are extracts from flowers that take out all the beneficial parts of the plant, like the resin and oils, while leaving behind the plant matter. There are several methods for making concentrates, with the “BHO” method being the most popular.
However, there’s a newcomer to the concentrate market that’s making waves with smokers. Rosin extraction involves pressing the dry or frozen herbs between two hot plates. You place the flower on some parchment, heat the plates in the press to the required temperature, and the pressure and heat remove the oils and resin from the plant matter.
This method requires no butane or hydrocarbons, meaning it’s a much safer final product for your health.
What is a Rosin Micron Bag?
Before you press your herb, you’ll stuff it into a “Rosin micron bag.” This bag has microscopic holes allowing oils and resin to flow out of the bag and onto the parchment. Without the rosin bag, you’re just going to end up with a sticky mess.
Think of the rosin micron bag like a coffee filter. You get all the coffee goodness in your cup without any of the grounds. The rosin micron bag comes in several sizes and with different mesh sizes.
What are Micron Units?
Rosin bags come in “micron” sizes. A micron is a scale of measurement and part of the metric system. One micron is equal to one-millionth of a metre (around 39-millionths of an inch).
Consider that human hair is around 50 microns thick, and our eyes can’t see anything under 40-microns. So, microns are a very small unit of measurement, and we use them in measuring the size of rosin bags.
How Do You Use a Rosin Micron Bag?
The rosin micron bag comes flat from the manufacturers, requiring you to turn it inside out before use, like a pillowcase. You’ll grind your favourite legal herbs in your grinder as normal and then add them to the bag.
Fold the end of the bag over to prevent any herb from escaping, and place it between a folded sheet of parchment paper on the rosin press.
Drop the plates onto the bag and squeeze them to the recommended pressure. The hot rosin bleeds through the micron holes in the rosin bag, leaving behind the plant matter. As a result, you have fresh rosin concentrate on the parchment, with no plant matter contaminating the concentrate.
What size Rosin Micron Bag do I Use?
Rosin micron bags are available in a range of sizes to suit your concentrate requirements. Typically, most bags range between 25 and 180-microns. The size of the bag determines the type of material used during the press.
- 25u-90u is ideal for sift, water, or bubble hash
- 90u-180u is good for flower or trim.
