How to Grow Notorious THC: Tips for a Thriving Grow

If you’re looking for high-yielding cannabis strains with real bag appeal, Notorious THC hits the mark. Here's what you need to know if you're considering it for your next run.

Indoor Growing

Flowering Time: 8–9 weeks
Height: Moderate to tall (LST and topping recommended)
PPFD Target: 900–1200 µmol/m²/s during flower
DLI Target: 35–45 mol/m²/day
Nutrients: Responds well to full feeding schedules — be sure to dial in CalMag.

Pro Tip: Keep airflow strong during late flower. The dense colas can get chunky — too chunky — and prone to mold without proper circulation.

Why Grow Notorious THC?

Here’s why Notorious THC is worth a spot in your garden — especially if you’re after top-tier homegrown weed:

Extreme Potency: Not a marketing gimmick. Consistently tests over 30% THC with a balanced high.
Bag Appeal: Dense, frosty buds with dark greens and purples — pure fire in the jar.
Smell-Proof Challenge: If you’re growing indoors, be warned — this strain stinks (in the best way). You’ll need a solid carbon filter setup.
Genetic Stability: As expected from Humboldt Seed Co., plants grow uniform and respond predictably to training.

It’s not beginner-friendly, but it’s incredibly rewarding for intermediate to advanced growers looking to maximize yield and potency.

Grower’s Journal: Our Experience With Notorious THC

I ran Notorious THC from clone under LED bars in a 3x3 tent using Botanicare nutrients and an AutoPot system. Here's a quick snapshot of our grow cycle:

Veg Time: 5 weeks
Flower Time: 63 days
VPD: 1.2 during early flower, 1.5 late flower
EC: 2.0 peak feeding
Lighting: ~1200 PPFD across canopy

Observations:

Strong vertical growth — topping at least twice is a must.
Responded well to Liquid Karma and Silica Blast — tight node spacing and solid stem structure.
Smell became intense around week 6 of flower — skunky garlic and cookie gas.

I grew four Notorious THC plants in 3.9-gallon pots under a 240-watt LED light. The final dry yield was 14 ounces total, averaging 3.5 oz per plant. Buds were rock hard, frosty, and sticky to the touch even after cure — with intense bag appeal and a nose that punches through the jar.

Common Questions About Notorious THC

Is Notorious THC too strong for beginners?

Yes — at least when it comes to smoking. The high is intense and can overwhelm inexperienced users. Start low and go slow.

Can beginners grow Notorious THC?

Technically yes, but this strain rewards experienced growers who can control environment, nutrients, and training. If it’s your first grow, expect a learning curve.

Use airtight glass jars with a humidity pack (58–62%). This strain is so loud it can easily leak through less secure storage.

Absolutely — if you’re ready for the challenge.

Notorious THC from Humboldt Seed Co. is a potent, flavor-packed strain that rewards careful growers with top-shelf buds that can rival dispensary weed.
