What Customers Are Saying
White Widow buyers talk about the flavor and the balance more than the strength. These are verbatim, pulled from the review pool on this product rather than written for it.

“I got the White Widow THCa cartridge, I would say it is hybrid like described but more sativa dominant.”

What Is Inside the White Widow Cart
One gram of White Widow live resin and the terpenes that came off the same plant, in hardware that runs cool enough to keep them. Caryophyllene leading a hybrid is uncommon, and it is most of why this one reads peppery rather than sweet.
🔥
Live Resin THCa
A full gram, frozen the day it was cut, which is the only way the floral note reaches you.
🌶
Beta-Caryophyllene
Leads here, unusually. Peppery, and the one terpene known to bind a cannabinoid receptor.
🌿
Beta-Myrcene
Second, supplying the body underneath a head-forward strain. It keeps the lift comfortable.
🍋
d-Limonene
Third, and the citrus that opens up behind the florals a second into the draw.
🔌
Ceramic Core, 510 Thread
Heats evenly at low voltage and fits whatever battery is already in the drawer.
🚫
Nothing But Oil and Terps
No PG, no VG, no MCT oil, no Vitamin E acetate. Oil and terpenes, and nothing stretching either one.
Science Corner: What the Frost Actually Is
White Widow is named for how heavily frosted the flower gets, and that frost is not decoration. Those crystals are glandular trichomes, the structures where the plant manufactures and stores both cannabinoids and terpenes. A 2020 study in The Plant Journal imaged them under two-photon microscopy and found the stalked variety carried blue autofluorescence that tracked with high cannabinoid content, held 12 to 16 secretory cells apiece, and ran strongly monoterpene-dominant terpene profiles. Sessile trichomes behaved differently. So a strain that frosts this heavily is producing more of the material an extractor wants, and the name is a description of the chemistry rather than a marketing flourish. PubMed PMID 31469934.
How It Works and How Much To Start With
A cart reaches you inside a couple of minutes and finishes arriving by fifteen, which makes it the easiest format to judge by feel. White Widow tests that in an unusual direction: it lands in the head first, so people expecting weight sometimes assume nothing has happened.
Something has. Take one draw, wait ten minutes, then decide, and resist the urge to treat the absence of a body hit as an absence of effect. Inhaled effects taper across two to three hours.
| Format | Onset | How long | Character |
| White Widow THCa cart, sold here | 2 to 5 minutes | 2 to 3 hours | Head first, body second |
| White Widow THCa vape pen | 2 to 5 minutes | 2 to 3 hours | Identical oil and curve |
| THCa flower | Under 2 minutes | 1 to 2 hours | Quickest on, shortest tail |
| THCa prerolls | Under 2 minutes | 1 to 2 hours | Same lift, fixed dose |
| Delta 8 carts | 2 to 5 minutes | 2 to 3 hours | Considerably milder |
| Edibles | 30 to 90 minutes | 4 to 6 hours | Slowest on, hardest to judge |

White Widow THCa Cart FAQ
A White Widow THCa cart is one full gram of live resin oil pressed from a single strain, threaded onto a standard 510 fitting. White Widow is a hybrid, and an unusually even one, which is part of why it has stayed on menus since the 1990s while fashionable strains came and went. Live resin means the flower went into a freezer the day it was cut rather than onto a drying rack, and that choice is what preserves the floral top note. Dry the plant first and the florals are the first thing you lose. Any 510 battery you already own will run it, so nothing proprietary and no adapter to hunt for. If a battery is already in your bag, this is the only thing you need to add to it.
Because of how it looks, not how it behaves. White Widow grows so heavily frosted in trichomes that mature flower reads visibly pale, almost dusted, and that frost is where the name came from in the Dutch scene of the early nineties. Those trichomes aren’t decoration either. They’re the glands that manufacture and store both the cannabinoids and the terpenes, so a strain that produces them densely is producing more of the material an extractor actually wants. The Science Corner further down gets into what researchers found inside them. Short version: the frost and the potency are the same thing looked at from two different angles, which makes this one of the few strain names that is actually describing chemistry.
Florals first, then citrus, then wood and fresh green herbs, with a gassy note holding it together underneath. It’s the least sweet cart we make and the one people reach for when dessert flavors have worn thin. Nothing here tastes like candy or fruit punch. The floral opening is the fragile part of the profile, which is why the extraction method and your voltage both matter more on this strain than on a gassy one. Run it hot and you’ll land somewhere generic. Run it cool and the florals stay where they belong, at the front of the draw rather than lost behind the gas. It’s a strain that rewards patience with the voltage dial, and punishes impatience faster than most of the menu does.
Daytime, or really anytime, and that flexibility is the pitch. Customers describe it as balanced and social: an energetic head with just enough body underneath to stay comfortable, rather than a lift that leaves you wired. It’s the cart to own if you want one that behaves at two in the afternoon and still works at nine at night. Compare that to King Louis XIII, which closes the day down, and Runtz, which sits in the middle. One customer described it as more of a thinker than a body strain, and that lines up with what most people tell us. If you want a single cart that doesn’t dictate the shape of your day, this is the one to own.
The whole THCa cart line runs 22 to 28% THCa, so White Widow isn’t stronger or weaker than its siblings on paper. What differs is how it delivers. It leans a little sativa in practice despite the balanced label, so the effect shows up in the head before the body notices, and people who expect heaviness sometimes think it hasn’t worked yet. It has. Give it the standard ten minutes after one draw before deciding anything. If you’re coming off indica carts this will feel lighter rather than weaker, and those are genuinely different things. Lighter means it leaves you room to keep going with your day. Weaker would mean it left you wanting more, and it doesn’t do that.
Sixty dollars for a single full gram. Two carts run $100 and three run $150, saving $20 and $30 against buying them individually. Subscribe and save takes 20 percent off your first order and 15 percent off every one after, cancellable at any point. There’s no battery in the box, since most people shopping 510 carts already have one, and our batteries page carries four that fit if you don’t. Per gram this is the least expensive way to buy the strain from us once you own hardware. On a first order the all-in-one pen is better value, because the battery comes with it and you skip a second purchase entirely. After that first one the cart is cheaper every time you reorder.
Any 510-thread battery fits. Voltage is where this strain is fussier than most: our battery guide puts the low band at 2.5 to 3.0 volts and White Widow genuinely belongs there, because the florals are the first thing heat destroys. A hot draw on this cart tastes like any other cart, which defeats the purpose of buying this one. Screw it on finger-tight and stop, since overtightening is the most common reason a cart won’t fire. All four batteries we sell have adjustable voltage and a one-year warranty. Charge yours fully before the first draw of a new cart, since a half-empty battery delivers a lower effective voltage than its setting suggests, and you’ll end up blaming the cart for something the battery did.
Yes. Plan around that rather than hoping. Standard urine panels look for THC metabolites and cannot distinguish a hemp-derived product from anything else, so federal compliance buys you nothing at the lab. Detection depends on how often you use it, your body composition and where the panel sets its cutoff, so an honest answer is a range rather than a number. Occasional users often clear within days. Daily users can test positive for weeks afterward, and there is no way to shorten that window on purpose. If you face testing for work, probation or competition, this is not the product for you, and we would rather say so plainly than take the order and leave you to find out afterward. No product is worth that.
In most states, yes. Hemp-derived products holding less than 0.3 percent Delta 9 THC by dry weight sit inside the 2018 Farm Bill, and this cart is one of them. Individual states add their own rules on top, and a handful restrict THCa or hemp vapes specifically. We keep the shipping list current, and checkout will tell you if your address is out of reach, which makes checkout a better source of truth than any page written weeks ago and not looked at since. Put it in the cart and enter your address if you are unsure. You need to be 21 or older to order. Orders leave the facility within 48 hours, and if your state has moved recently the checkout knows about it before this page does.
Different hardware, identical oil, and the choice is mostly about whether you own a battery. This page is the cart: a gram on a 510 thread, cheapest per gram, and it assumes you have something to screw it into. The White Widow vape pen is the all-in-one, charged on arrival, battery built in, and it’s the one to buy first if you’re starting from nothing. Reordering, or already stocked with batteries? Take the cart. The White Widow strain profile covers lineage and terpene order in more depth than a product page should, including why caryophyllene leads a strain most people assume is citrus-forward, and what that does to the way it actually feels in practice. Same oil in both formats, so this really is a hardware decision.
Floral, citrus and wood, in the format that costs the least per gram.
