Mamba Negra CBD Feminized takes the edge off without taking over. With easy growth, mellow vibes, and sweet earthy flavor, it’s a no-nonsense choice for calm seekers and beginner growers alike.
Not every strain is about knocking your socks off. Some are made for the quiet moments, when you need calm, not chaos. Mamba Negra CBD is one of those strains. With barely 1% THC and a seriously generous 20% CBD, it’s ideal if you’re looking to unwind, take the edge off, or get some proper sleep without getting zonked. Easy to grow, mellow to smoke, and pretty as hell when she’s in full bloom, this one’s a favorite for beginner growers who want a reliable, therapeutic strain that doesn't ask much in return.
Mamba Negra CBD Fem is the result of a well-considered genetic mix: Critical Mass, Skunk, and Painkiller XL. That combo gives it the solid structure and yield of Critical, the aromatic charm of Skunk, and the soothing power of a true CBD-dominant hybrid. This isn’t some tossed-together side project. It’s been bred for purpose. And it shows.
Don’t expect fireworks. Expect a warm blanket. The high-CBD profile delivers a deeply relaxing, almost sleepy body calm. Your muscles slacken, your mind quiets down, and if you're already horizontal, you probably won’t be moving for a while. It’s not the strain to rev you up. It’s the one to bring you back to baseline. Flavor-wise, it leans into sweet earth and soft blossoms, with a hint of berry that comes through strongest on the exhale. The floral note lingers nicely too, without turning perfumey.
With just 1% THC, there’s next to no psychoactive buzz here. That’s the point. The 20% CBD makes it ideal for users who want relief, whether physical, mental, or emotional, without the headspin. It’s perfect for nighttime use or whenever your body needs to settle.
This mellow queen is led by myrcene, which helps bring on that full-body calm. Limonene brightens the flavor just enough, while linalool adds a floral softness. Humulene sneaks in with a slightly herbal, woody edge that rounds things out and gives it a clean finish.
This strain is forgiving. You don’t need a chemistry degree or a lifetime of grows under your belt to get a decent harvest. It’s tough against mold, tolerant of errors, and just does what it’s supposed to do. A solid pick for first-timers who want to keep things simple and still walk away with a therapeutic stash.
Indoors, Mamba Negra CBD Fem stays fairly manageable, stretching from 120 cm up to around 170 cm at most. Outdoors, she can shoot up from 140 cm to 210 cm if you give her the space and sun. She handles both environments well, including greenhouses, and is especially reliable in temperate or Mediterranean climates. That said, she can also take on more humid zones thanks to her resistance to fungal problems.
She’s not the fastest finisher, but still clocks in within a very reasonable 56 to 70 days. Indoors, yields can range from 400 grams per m2 to 550 grams per m2. Outdoor plants can give you between 500 grams per plant and 700 grams per plant if they’re well cared for. Not bad for a chill, low-effort grow.
Whether you’re looking for calm, clarity, or just a better night’s sleep, Mamba Negra CBD brings the goods without the buzz. With top-tier genetics, beginner-friendly grow traits, and knockout CBD levels, she’s as practical as she is therapeutic. Pick up your feminized seeds today at WeedSeedsExpress. Fast shipping, discreet packaging, and a germination guarantee included.
