What Are Dry Herbs?
Dry herbs refer to the dried flowers and leaves of the hemp plant, sold whole or ground. The flower has the highest concentration of CBD because that's where the plant's trichomes (small resin glands) develop, while the leaf material adds bulk and a milder profile to a blend. Because nothing is extracted, dry herb keeps the plant's naturally occurring terpenes and cannabinoids intact, which is part of why the flavour and effect differ from a CBD oil or e-liquid made from the same hemp. When you shop dry herbs, the percentage on the pack tells you the strength directly, since nothing has been diluted into a carrier.
What is a Dry Herb Vaporiser?
A dry herb vaporiser heats hemp flower or leaf to a set temperature, low enough to release cannabinoids and terpenes as vapour without burning the plant. Most devices use conduction, where the herb sits directly against a heated chamber, or convection, where hot air moves through the herb instead. CBD dry herb vaporisers let you control exactly how much heat the plant gets, which changes both the strength and flavour of each session. Portable models run on rechargeable batteries and heat up within a minute or two, while desktop units plug in and reach temperature more slowly.
How Do CBD Dry Herb Vaporisers Work?
Conduction models place the herb directly against a heated ceramic or metal chamber, which warms fast but can scorch the edges if the temperature runs too high. Convection models push hot air through the chamber instead, heating the herb more evenly and preserving more of the flavour. Combustion typically starts around 230°C, so most devices stay well below that, usually between 160°C and 220°C.
How to Store Dry Herb Blends?
Light and heat break down the cannabinoids and terpenes in dry herb over time, so an airtight, opaque container kept in a cool, dark cupboard preserves potency and flavour for longer. Avoid the fridge, since moisture building up inside a sealed container in cold conditions encourages mould. Most blends keep their character for six months to a year when stored this way, though flavour tends to fade before the CBD content does.
FAQ
-
CBD dry herb is legal to sell in the UK when its THC content stays within the legal exempt limit, and the hemp comes from an approved industrial strain. Most retailers still label these blends for aromatherapy or collection, since raw cannabis flower remains a controlled plant material regardless of THC content.
-
Vaping heats herb without burning it, so it avoids the tar, carbon monoxide and other toxins that combustion produces. It also tends to use less material for the same effect, since heat releases cannabinoids more efficiently than a flame does.
-
The device itself is safe when used as intended, and choosing lab-tested CBD dry herb with a clear certificate of analysis confirms exactly what's in each batch. As with any CBD product, it's worth keeping daily intake moderate and checking with a doctor if you take other medication.
