Critical Mass CBD by Oaseeds Genetics

Critical Mass CBD Strain Info

Imagine crossing a legendary heavyweight like Critical Mass with a pure CBD champion and getting the perfect balance between power and peace—well, that’s exactly what this strain brings to the table.

Critical Mass CBD by Oaseeds Genetics is that friend who always knows how to chill you out without knocking you out.

It’s a feminized cannabis seeds version, born from the marriage of Critical Mass and a pure CBD clone, designed for growers who want generous buds and calm vibes.

This mostly indica (80%) strain grows like it’s got something to prove—stocky, bushy, and absolutely packed with dense, chunky flowers that feel like squeezing a sponge full of resin.

Her buds are tight, heavy, and practically dripping in trichomes, making her a favorite among extract lovers and resin freaks.

She’s not shy when it comes to production either, stacking those thick colas like she’s in a bulking season.

Flowering Time & Yield

You won’t have to wait forever to enjoy her gifts—she flowers in just 55 days indoors, which means quick turnarounds and more harvests per year if you plan it right.

Growers working indoors can expect up to 600 g/m² (21.2 oz/ft²) of compact, resin-rich nuggets that look like they’ve been dusted with sugar.

Outdoor growers, buckle up—under the sun, she can stretch a bit and reward you with up to 1200 grams per plant (42.3 oz/plant), ready to chop around early October.

Effects and Aroma

This girl isn’t here to mess with your head—her CBD content ranges between 20-24%, while THC stays at a mild 0.7–0.9%, giving you that sweet body relaxation without the mind fog.

Perfect for winding down, melting muscle tension, or catching Zs after a long day, she’s like a cozy blanket and a mug of lemon tea rolled into a joint.

The first puff hits with a bright, lemony citrus punch that tingles the nose and dances on the tongue.

Then comes the calm—deep pine wood and exotic forest notes that make you feel like you're breathing in fresh mountain air at sunrise.

The aroma is intense, sweet and slightly tangy, with a background of warm wood and sticky resin that clings to your fingers and your memory.

If you’re looking for CBD-rich marijuana seeds that deliver high-quality buds, a smooth growing experience, and a calm, therapeutic effect, Critical Mass CBD seeds won’t disappoint.

Grow Tips & What We Love About It

If you're looking for Rich-CBD Seeds that doesn’t make you sweat with every grow cycle, this one’s got your back.

Critical Mass CBD is surprisingly easy to grow, even for newbies still figuring out what a pH meter is.

She thrives both indoors and out, but really shines when given a stable, warm, and dry climate—think Mediterranean vibes, around 20–26°C (68–79°F).

Humidity isn’t her friend during late flowering, so good airflow and some defoliation will help keep those dense buds happy and mold-free.

We’ve noticed she handles pests like a champ—spider mites, powdery mildew, and aphids don’t seem to stand much of a chance when she’s healthy and well-fed.

Still, we always recommend a preventive treatment with neem oil or biological predators, just in case.

She responds beautifully to pruning and training, especially if you want to maximize that central cola or go full sea of green.

What really grabs us every time is how those fat, sticky buds keep getting bigger without compromising on quality.

She fills up your grow tent like it’s her personal stage, and every harvest feels like you’ve just scored the jackpot at a CBD casino.
