Solventless extraction processes require the utmost care and attention to detail, to ensure a high-quality finished product. There are several common mistakes that may compromise the quality and potency of your hash or rosin.

In this blog post, we will discuss five of the most common mistakes and how to avoid them.

The quality of your starting material is critical.

Using old, poor quality cannabis flower will result in an inferior final product, no matter how skilled you are at solventless extraction. To ensure the best results, use fresh, high-quality cannabis flower that has been harvested, prepared, and stored correctly for cold water extraction. Incorrectly stored or improperly grown material is likely to produce a hash or rosin that is dark and flavourless.

2. Using too much ice during extraction

Ice is commonly used to create bubble hash.

Too much ice can dilute and reduce the potency of your final product, as ice can introduce various contaminants. This is why Whistler Technologies is adapting equipment design to facilitate iceless solventless extraction

Ice should be used to cool the process water, not to enhance agitation. The goal is to achieve a gentle and efficient extraction. Excess ice can also make the extraction process more difficult and time-consuming, so it is important to monitor process temperatures and only add ice when necessary.

3. Lack of PPE

Producing the highest quality bubble hash starts with one essential step: wearing appropriate personal protective equipment (PPE).

Always wear gloves, a lab coat or apron, and a hairnet  when handling starting material, equipment, storage containers, and any hash or rosin throughout the process. Additionally, it is important to use clean and fitted PPE to avoid introducing any foreign material or bacteria into the product.

Failure to use appropriate PPE can compromise the quality and safety of the final product. It can also potentially lead to adverse health effects for consumers.

4. Excessive use of force during agitation and pressing

Agitation and pressing are essential steps in creating solventless hash and rosin, but it is important to use the right amount of force.

Over-agitating your starting material can break apart the trichomes and reduce the quality of your final product. Similarly, using excessive force while pressing can result in harsh, burnt-tasting rosin. It is important to find the right balance of force and time to achieve the best results.

5. Improper storage of your end product

Once you have created your solventless hash or rosin, it is important to store it properly to maintain its quality.

Exposure to light, heat, and air can cause the cannabinoids and terpenes to degrade over time, resulting in a less potent and less flavorful final product. Store your hash or rosin in a cool, dark place in an airtight container to ensure the best results. It is also important to keep your storage container clean and free of any contaminants to avoid compromising the quality of your end product.
