Last few years concentrates/extractions became very populair and well known in the cannabis industry. Concentrates like hash or kief are well known for lots of years but the very pure concentrates like BHO or rosin press is quite new. BHO was first in this genre but it required some expensive equipment and you have to know how to use this equipment to get a good product. Later they discovered that you are able to get the same kind of extraction when pressing cannabis between 2 hot plates. When a concentrate is made by this method it’s called: Rosin!
Since pure pressure rosin press got introduced to the cannabis scene, it became very populair very quickly. Not only because of the good looking product but also because it was pretty easy to make and you don’t always have to buy expensive equipment. (There are very expensive presses, but you don’t necessarily need to get one of these)

When pressing, everybody has their own techniques and every press/temperature works different on different strains. These kind of differences leads to differeces in rosin. There are multiple reasons that could be the cause of your rosin turning out dark/bad
The quality of your pressing/flower material is one of the most important aspects of pressing good rosin. There is a saying that goes: Garbage in, Garbage out which simply means that the quality of the material going in to your press, is the same quality of rosin coming out. This is absolutely true and should be the first thing to check if your rosin turns out black/dark.
Another reason to check your buds is the fact that cannabis ages over time. This causes the level of cannabinoids in your material to drop, the oxidization process and light will lower the quality and change the colour of trichomes into amber. Next to that some terpenes are air-volatile and even more effected by age. You shouldn’t wait too long before pressing your material if you want your rosin press canada to be clear.

To get top quality rosin you should definitly use fresh cannabis, experts say that material which is around 4-5 days old (picked of the plant) is perfect to press. Another method to get very clear/good rosin: Shock freeze or use fresh cannabis, makeice bubble hasj (Ice wax) out of it and finally press it. By freezing your cannabis right after it’s cut down, you keep all trichomes and terpenes intact and fresh. This extract is called Live Rosin and leads to the best quality according to most experts.

Another important aspect to improve colour of your rosin is the moment you harvest. It’s recommended to cut them down a little earlier as normal because trichomes won’t be turned into amber yet which also leads to a better/lighter coloured rosin.

If you are not growing yourself yourself, it could be quite tricky to find fresh, potent material for your rosin press machine compared to commercial growers. Try to find fresh material or get to know some people in the scene!
