Mountaintop Mint Feminized Seeds – Humboldt Seed Company’s Minty, Knockout Hybrid

Mountaintop Mint Feminized Seeds from Humboldt Seed Company are a top-tier hybrid designed to deliver a sensory knockout punch, combining an intense spearmint candy aroma with a deeply relaxing, mind-numbing effect.

Are you tired of chasing that perfect, unique terpene profile that stands out in a sea of generic flavors? You invest time, energy, and hope into your grow, only to end up with another plant that smells and tastes like everything else on the market. It’s frustrating when your harvest doesn’t have that ‘wow’ factor you were promised.

This lack of distinct character means your hard work yields a product that blends in instead of standing out. You miss out on the full, memorable experience that makes growing truly rewarding.

Mountaintop Mint is the definitive solution. Bred from the legendary The Bling and Mac Mints, this strain was elevated to a full breeding project after its stellar 2019 performance precisely because of its outrageous and unmistakable mint profile. It’s not a subtle hint; it’s a full-blown spearmint and menthol explosion with a skunky finish that will redefine what you think cannabis can smell and taste like.

What Mountaintop Mint Does For Your Grow

This strain is a grower’s dream for those seeking both exceptional quality and satisfying yields. It’s a fairly variable plant, meaning you might find different expressions of its minty goodness, but all phenotypes deliver on the core promise: insane terpenes and a heavy-hitting effect. The plants are productive and develop extremely dense buds, so good ventilation is key to prevent mold and maximize those frosty, resinous flowers.

How to Grow Mountaintop Mint Successfully

To get the most out of these seeds, a few key steps will set you up for success. Start with a high-quality, well-aerated substrate to encourage strong root development from the get-go.

1. Germination & Seedling: Germinate in a warm, humid environment (22–26 °C / 71.6–78.8 °F). Once sprouted, provide mild light and careful watering. A product like Orca Liquid Mycorrhizae can significantly boost early root establishment and plant vigor.
2. Vegetative Growth: Maintain an 18/6 light cycle. This strain shows good vigor. You can apply low-stress training (LST) to manage height and improve light penetration to lower bud sites. Keep temperatures between 22–26 °C (71.6–78.8 °F) and humidity around 50–60%.
3. Flowering Transition & Bloom: Switch to a 12/12 light cycle to induce flowering. You’ll see a noticeable stretch. This is when the intense mint aroma will begin to develop. Lower humidity to 40–50% to protect the dense buds. Ensure strong air circulation. To support massive bud development and resin production, consider a flowering booster like Brutal Bloom during the peak flowering phase.
4. Harvest & Cure: Harvest after approximately 70 days of flowering when trichomes are mostly milky with some amber, depending on your preferred effect. After a proper flush, dry slowly in a dark environment at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 10–14 days. Cure in jars for a minimum of 2–4 weeks to allow the minty flavors to fully mature and smooth out.

Frequently Asked Questions

How strong is the mint smell while growing?

The mint aroma is intense and dominant. It’s described as “insane” by the breeder. Using a carbon filter is highly recommended, especially in the later flowering stages, to manage the strong scent.

Is Mountaintop Mint suitable for beginner growers?

It’s rated as medium difficulty. While the genetics are stable, the dense bud structure demands good environmental control (humidity and airflow) to prevent issues like botrytis. Beginners who are diligent about their setup can succeed.

What’s the best way to train these plants?

Low-Stress Training (LST) is highly effective. It helps manage height, opens up the canopy for better light penetration, and can improve yields. Topping can also be done during early vegetative growth.

How long does it take from seed to harvest?

As a photoperiod strain, the total time depends on your vegetative period. Typically, with a 4–6 week veg and the 70-day flower period, you’re looking at roughly 14–18 weeks from seed to harvest.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve run Mountaintop Mint a couple of times in our test tents, and it never fails to impress visitors. The first thing everyone says is, “Wow, it really does smell like a pack of spearmint gum in here!” It’s not a subtle, herbal mint—it’s that sharp, candy-like spearmint that fills the room. The plants are vigorous growers and definitely need their space; I wouldn’t overcrowd them.

The high is exactly as advertised: a knockout. It’s not a racy, paranoid high; it’s a heavy, settling stone that starts behind the eyes and melts down through the body. It’s my go-to for shutting my brain off after a long day. The only real con is the flowering time—you need patience for those 70 days—but the wait is absolutely worth it for the unique flavor and potent effect. Just make sure your exhaust fan is working overtime during the last few weeks!
