Quick and Easy Extracts

Extraction of plant extracts is both a science and an art that makes it possible to obtain the best from plants — from valuable terpenes to active compounds — while removing unwanted components such as waxes, fats and plant material. Whether you choose solvent-based methods or a safer solventless route, the key is selecting the right procedure. Dive with us into the fascinating world of extractions, where traditional approaches meet cutting-edge technologies, and discover how each can affect the final product.

The goal of extraction is to separate active components (terpenes, active compounds) from unwanted ones such as fats, waxes or plant material. Various techniques to achieve this are divided into two basic categories depending on whether solvents are required for the extraction.

Solvent-based extraction: These extraction methods use organic solvents (butane, ethanol, isopropyl alcohol, dimethyl ether, CO₂) that separate trichomes (resin) from the organic material. This is followed by a separation process in which the resulting extract is heated, stirred or otherwise processed to produce a concentrated product.

Solventless extraction: Solventless extraction methods include a range of techniques from traditional sieving to modern water separation and pressing. In these techniques, trichomes are separated from the plant material mechanically, using agitation, pressure, heat or cold.

Each of the extraction methods mentioned above has its advantages and disadvantages. The main differences between techniques are yield and quality of the final product. The types of extracts obtained differ in appearance, structure, consistency, active compound content and purity, depending on the quality of the starting material and the extraction processes used.

Solventless extraction methods

/>The main advantages of solventless extraction are safety and relatively low equipment costs. These techniques give growers confidence that the final product will be non-toxic. In addition, there is no risk of poisoning or injury associated with the use of flammable solvents during production.</p>
<p><strong>Sieving</strong></p>
<p>Sieving (dry sift) is among the oldest methods of extracting resin used by growers worldwide for centuries. In this technique, dry plant material (buds, leaves, trim) is passed through fine screens with tiny holes that allow only trichomes to pass through. Resin is released from the dried material by mechanical movement and takes the form of a sticky powder that can be further pressed, cleaned or processed.</p>
<ul>
<li><strong>Hand dry-sift screens</strong> are suitable for home growers and those who want maximum control over the extraction process. Using multiple mesh sizes you can capture different trichome sizes, which allows you to decide on the quality of the final product.</li>
<li><strong>Automatic pollinators</strong> operate on the same principle as hand screens but are equipped with a motor that sifts the material, speeding up the work.</li>
</ul>
<p><strong>Water extraction</strong></p>
<p>Ice-water extraction builds on sieving and involves submerging plant material in a mixture of ice and water, then stirring and draining through bags with mesh bottoms. Cold water helps release trichomes, allowing for a cleaner product than dry sieving.</p>
<ul>
<li><strong>Extraction bags for pollen separation</strong> with various mesh sizes are the basic tool for water extraction. To start you will need a basic set of three bags (220, 73, 25 microns): the largest mesh (220 µm) catches debris and plant material, the middle mesh (73 µm) catches the heads of the largest trichomes, and the bottom mesh (25 µm) collects the remaining resin.</li>
<li><strong>Pollen separation washers</strong> facilitate mixing and the subsequent draining of water through the screens. With gentle but thorough stirring you can achieve higher yields and a cleaner product than with manual processing.</li>
</ul>
<p><strong>Heat pressing</strong></p>
<p>Pressing is a modern extraction method in which plant material or resin obtained by sieving or water separation is pressed and heated to separate excess waxes and oils from the product. The result is a very clean product with a high content of terpenes and active compounds. The advantage of heat pressing is the high quality of the extract and the absence of solvents. This method requires a special hydraulic press with heated plates.</p>
<ul>
<li><strong>Manual presses</strong> are suitable for home growers and for those who want to try this method for the first time.</li>
<li><strong>Automatic resin extraction presses</strong> are somewhat more expensive than manual ones, but can achieve better results.</li>
