Chemdawg 4 by Oaseeds Genetics

Chemdawg #4 Strain Info

If you’re chasing legends, Chemdawg #4 is one of those mythical strains that feels like it’s been passed around at the best sessions since forever.

It carries a heavy dose of American cannabis history, straight from the Grateful Dead tour buses to the Emerald Triangle hills.

Born from the cross between Chemdog and Green Crack, this hybrid has indica dominance but surprises you with sativa-like growth spurts that stretch toward the sky like it’s trying to high-five the sun.

Forget short and bushy—Chemdawg #4 is lanky, bold, and not afraid to take up space, reaching over 2 meters (6.5 feet) outdoors if you let her do her thing.

She grows like she’s in a race, throwing out deep green leaves and long internodes with wild energy, always hungry for light and nutrients.

The buds she produces look like they’ve been sprinkled with diamond dust—lime green nugs covered in orange hairs and glistening trichomes that could blind you under the right light.

Flowering Time & Yield

Chemdawg #4 doesn’t keep you waiting forever either—she flowers in about 8 to 10 weeks, giving growers just enough suspense before delivering the goods.

Indoor setups can yield around 450 to 500 grams/m² (15.8 to 17.6 oz/ft²) of top-tier resin-packed buds that make trimming day feel like Christmas morning.

Outdoor growers harvesting around mid to late September are rewarded with bushes that don’t just grow—they thrive, producing weighty colas that demand support from nets or cages to keep from snapping under their own juicy mass.

And when she’s happy in the right outdoor conditions, she can tower up to 3 to 4.8 meters (10 to 16 feet) like a green monolith of funk.

If you're into feminized cannabis seeds, this one’s a no-brainer for your garden.

Effects and Aroma

Light her up and you’re hit with a blast of lemon zest, spicy pine, and raw diesel that grabs your nose and drags you into the smoke like a summer storm.

Think citrus-scented cleaning products collided with peppery gas fumes in the best way possible—an aroma that lingers, sticks to your fingers, and makes you sniff your jar three times a day just because you can.

The flavor? It matches the nose but kicks even harder—lemony, earthy, and gassy all at once, like sipping lemonade next to a gas station in the forest.

And then comes the hit—a fast-onset cerebral high that lifts the mind with clarity and euphoria before slowly melting into body-numbing relaxation that’ll have you questioning whether you even need a couch anymore.

Chemdawg #4 is excellent for pain relief, sleep, and deep unwinding, but go easy—this girl can pack up to 26% THC and doesn’t play games.

If you’re into concentrates, she’s got the resin profile to turn your rosin press into your new best friend.

There’s a reason this Chemdawg strain has been a building block for other iconic genetics—it’s that damn good.

Grower Tips & What We Love Most

We always recommend giving Chemdawg #4 some extra love with support structures—her colas get heavy, and believe us, she’ll need a helping hand.

Big circular cages or strong trellis nets work wonders, especially when she stretches out and fills with dense, resinous buds.

What really stands out for us is her ability to explode in size and still keep those beautiful internodal gaps that let air flow freely—ventilation never feels like a problem with this one.

She’s not the kind of strain you just leave on autopilot, though.

Her metabolism is fast and she’s always hungry, especially for nitrogen during veg, so a strong feeding schedule is key to getting the most out of her.

As for disease resistance, she does have a slight sensitivity to powdery mildew, so we always take preventive steps ahead of time just to stay safe.

With proper spacing, pruning, and airflow, it’s easy to keep her clean and healthy throughout the cycle.

She performs best in warm, dry, Mediterranean-style climates, whether you’re growing in the ground or in massive pots under the sun.

In cooler or more humid regions, greenhouses can give her that extra protection she needs to reach full potential without stress.

We’d rate the difficulty level at intermediate—she’s not too fussy, but she rewards growers who pay attention and stay on top of her needs.

Once you get the hang of her rhythm, she becomes a joy to grow and a beast to harvest.
