Products & gear, and what to skip

We buy the gear, use it for weeks, and tell you what is worth it. Every pick links to where to buy, every affiliate link is disclosed, and no brand pays to be here.

A range chart on one Celsius axis. Decarboxylation 80 to 145 degrees, flower vaporizers 180 to 220 with a laboratory benchmark at 210, PAX Era modes 271 to 421, vape cartridge coils 420 to 543, and combustion off the top of the scale.
Four processes, one axis. Every band is a published measurement, not a rule of thumb.

One axis, four processes

420 °C

Where a cartridge coil actually sits

Gear is mostly an argument about heat. A butter infusion and a vape cartridge are two hundred degrees apart, and almost nothing written about either one says so.

The last band is the one to look at. Thermography found a temperature-controlled pod holding 420 °C to within about ten degrees, while voltage-controlled batteries averaged 443 to 543 and swung by fifty to a hundred between puffs. Combustion is hotter still — we have left it unnumbered, because every figure we could find for an ember was one we could not source.

Accessories Guides and hands-on reviews of accessories. Cannabutter Machines A cannabutter machine is a heated, stirred vessel that decarboxylates cannabis and then infuses it into fat. The chemistry it automates is simple and unforgiving: too little heat and nothing converts, too much and what converted degrades. Judge one on its temperature control before anything else. Grinders A grinder does two jobs: it reduces flower to pieces of even size so it burns evenly, and it collects the resin heads that would otherwise stick to your fingers. Three things decide whether one is any good: the tooth geometry, the micron rating of the screen, and whether the aluminium is properly anodised. Pre-Rolls A pre-roll is a ready-made joint sold over a dispensary counter. What is inside is not always flower: California defines a pre-roll as any combination of flower, shake, leaf or kief rolled in paper. Reading the label and looking at the grind is how you tell which one you are buying. Vaporizers A vaporizer heats cannabis until its active compounds come off as vapour without the material catching fire. How it applies that heat, not what number is on the dial, is what separates one from another: four devices run at an identical 210 degrees delivered between 54 and 83 per cent of their THC. Weed Subscription Boxes A weed subscription box is a monthly parcel of smoking accessories: papers, a grinder, a lighter and usually a piece of glass. Almost none of them contain cannabis, because the mail will not carry it. What you are buying is a recurring charge against contents you do not see in advance.
