How your garden transforms with Mouth Wash

Introducing Mouth Wash into your space means welcoming a robust and manageable plant. Indoors, its indica-dominant structure makes it a dream for techniques like SCROG or main-lining, allowing you to maximize your canopy and light penetration efficiently. You'll watch as thick, sturdy stems support heavy, resinous colas that glisten under the lights.

Outdoors, it transforms into a true spectacle. Given space and sun, it develops into a bushy, productive beast. The shift from vegetative growth to the flowering stretch is a sight to behold, as the plant dedicates all its energy to building dense, aromatic buds that often showcase stunning purple and orange hues as harvest approaches.

Steps to a successful Mouth Wash harvest

1. Start Strong: Germinate your seeds in a warm, humid environment (22–25°C / 71–77°F). Consider using a rooting stimulant to ensure a vigorous start.
2. Establish Vigor: Once sprouted, provide 18 hours of light daily. Keep humidity around 60-70% and use a light, airy substrate to encourage root development.
3. Guide the Growth: During vegetation, employ low-stress training (LST) to create an even canopy. This strain responds beautifully to topping and bending.
4. Initiate Flowering: Switch the light cycle to 12/12. Watch for the explosive stretch in the first few weeks as it focuses on bud production.
5. Support and Feed: Provide stakes or a trellis net to support the heavy branches. In mid-flower, a PK booster can enhance bud density and resin output.
6. Monitor and Harvest: Flowering takes 8-9 weeks. Harvest when trichomes are mostly milky with some amber for a balanced effect. In the Northern Hemisphere, expect ripe plants by early to mid-October.
7. Dry and Cure: Dry slowly in a dark space at 18-22°C (64-72°F) and 50-60% RH for 10-14 days, then cure in jars for at least 2-4 weeks to perfect the flavor.

Frequently Asked Questions

Is Mouth Wash suitable for beginner growers?

Yes, its resilient nature and forgiving growth patterns make it a great choice for beginners. Its stable genetics reduce surprises, allowing new growers to focus on learning the basics without too much stress.

How tall does Mouth Wash typically grow?

Height is variable and depends heavily on training and environment. Indoors, with techniques like LST or SCROG, you can keep it under 1 m (3.28 ft). Outdoors, with ample space, it can become a large, bushy plant exceeding 2 m (6.56 ft).

What's the best way to maximize yield with this strain?

Employ canopy management techniques like SCROG or main-lining indoors to create an even light distribution. Outdoors, topping and low-stress training early in veg will encourage multiple main colas. Providing ample root space in a final pot of 15–20 L (3.96–5.28 gal) and using a balanced nutrient regimen during flowering are key.

How strong is the smell during flowering?

The aroma is potent and distinct—a classic, earthy Kush scent with sweet and spicy undertones. Using a high-quality carbon filter in your indoor setup is highly recommended for discretion.

What kind of high does Mouth Wash produce?

It delivers a powerful, two-phase effect. It starts with a clear-headed, euphoric, and creative cerebral lift that gradually transitions into a deeply relaxing, full-body stone. Perfect for unwinding in the evening.

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you, Mouth Wash quickly earned a permanent spot in my personal rotation. I ran it in a mixed-strain tent, and its structure immediately stood out—incredibly robust stems that held up fat, rock-hard nugs without any need for extra support until very late flower. The stretch during the first two weeks of 12/12 was moderate but purposeful, filling the canopy perfectly under my SCROG net.

The real magic happened around week 6 of flowering. The room started smelling less like a grow tent and more like a classic Amsterdam coffee shop, with that unmistakable hash-like, earthy-sweet funk. I found the sweet spot with nutrients was slightly lighter on nitrogen in late veg and a solid PK boost around weeks 4-5 of flower, which made the trichomes absolutely explode. The yield was honestly impressive for the space it occupied; the main colas were so dense I had to be extra careful during drying to avoid any mold. The smoke? It's a creeper. The first few hits are smooth and flavorful, but within minutes you're locked into a heavy, satisfying stone that's perfect for after work. My pro-tip: don't rush the cure. Give those jars a full month, and the caramel notes really start to sing.
