A cannabis liquid for open tank systems gives you direct control over your cannabinoid choice, your flavour and your device. The Happy & Puff Liquids collection brings together 27 cannabis e-liquid options with many strain profiles, cannabinoid combinations and bottle formats, so you can match the liquid to your device and your taste.
Open tank vaporizers, also called sub-ohm tanks or refillable pod systems, work differently from sealed disposables. You fill the tank yourself, choose your coil resistance and control the airflow. A cannabis liquid for these systems needs the right thickness to soak into the wick without burning the coil. Happy & Puff liquids are blended to the thickness that open tank hardware needs, so you get the same vapor from the first draw to the last.
Because the tank is refillable, you are not tied to a single cannabinoid ratio or flavour. You can switch between profiles, fill half a tank to try a strain, or mix two liquids if your device allows it. This flexibility is the main reason many experienced users choose cannabis e-liquid over closed formats.
If you also use sealed hardware, the Happy & Puff pens and cartridges collection covers 510-thread cartridges and compatible batteries as a separate category.
The collection includes several cannabinoid combinations. THCA, T8HC, T9HC and CBG appear in different products, often with natural terpenes that match the aroma of specific strains. Strain profiles range from classic sativas with citrus and pine notes to indicas with earthy and fuel-like terpene blends.
The cannabinoid panel on each product page shows the main cannabinoid and any other cannabinoids in the liquid. Some liquids contain only one cannabinoid. Others combine several cannabinoids and terpenes in one bottle. The content of each one is listed in % or mg.
If you want to learn more about how strain genetics shape the aroma of a liquid, the Ghost Train Haze strain guide describes a THCA sativa profile that appears in several liquids in this collection.
Disposable vapes are all-in-one devices: battery, coil and liquid in one sealed unit. They are easy to use and need no maintenance, but the cannabinoid ratio, flavour and puff count are fixed by the manufacturer. When the unit is empty, it goes in the bin.
A cannabis e-liquid for open tanks lets you choose every part. You choose the hardware. You choose the coil temperature range. You choose how much liquid to fill and when to refill. You can switch strains during the week without buying a new device. The cost per millilitre of liquid is also usually lower than the same volume in a disposable, once you count the life of the device.
The trade-off is setup time and maintenance. Coils need replacing, tanks need cleaning, and a new coil needs to soak in liquid before the first use to avoid a burnt draw. If you are happy to spend five minutes on this, you get much more choice of device and cannabinoid.
If you prefer the simple sealed format, the Happy & Puff vapes collection covers disposable options with the same strains.
First, check that your device works with the thickness of the liquid. The product page shows the recommended coil resistance range, usually between 0.4 and 1.0 ohm for the cannabis liquids in this collection. Screw the coil into the tank, fill the tank to the maximum line, and then wait five to ten minutes before the first draw. This lets the wick soak up the liquid completely.
Start at a lower wattage setting and increase it step by step until you get the vapor density you like. Cannabis liquids show their full terpene flavour at moderate temperatures. A wattage that is too strong damages the terpenes and shortens the life of the coil. Replace the coil when the flavour changes or when you get less vapor.
Store open bottles upright, away from direct light and heat. Cannabinoids in liquid form keep well at room temperature, but they break down faster in UV light or at temperatures above 30 degrees Celsius. All liquids are for adults 18+ only. Keep them out of reach of children.
Browse the full range above and use the filters to compare by cannabinoid type, strain type and bottle size.
Every Happy & Puff cannabis liquid batch comes with a third-party laboratory certificate of analysis. It confirms the cannabinoid content and shows that there are no residual solvents, heavy metals or pesticides. Certificate links are available on each product page. Availability of products in this collection depends on your delivery country.
