Haze Special Regular Seeds by KC Brains Holland – Fast-Flowering Sativa for Indoor & Outdoor

The Haze Special Regular Seeds from KC Brains Holland are your express ticket to the legendary world of classic sativa highs, without the agonizingly long wait. This strain masterfully blends the iconic cerebral energy of Nevil's Haze with the robust structure of KC 606, creating a plant that's both a joy to grow and a powerhouse of uplifting effects.

Ever dreamt of harvesting that electric, mind-expanding sativa buzz but get discouraged by flowering times that stretch into the double-digit weeks? You're not alone. The promise of a Haze is often shadowed by the reality of a 14+ week commitment, testing the patience of even the most dedicated grower. That long wait means more time for things to go wrong, more resources spent, and a delayed reward that can feel like a lifetime away. It's the classic grower's dilemma: sacrifice speed for quality, or settle for a faster, less impressive plant.

KC Brains solved this puzzle with Haze Special. By introducing the genetics of their stable KC 606, they've tamed the wild flowering time of the Haze lineage while locking in its most desirable traits. The result? You get the distinctive, sharp Haze taste and the soaring, creative high you crave, but in a package that finishes in a timeframe that makes sense for your life. No more watching the calendar with dread. This is the solution for the grower who wants it all: legendary flavour, potent effects, and a harvest you can actually plan for.

Real Benefits You're Going to Notice

So, what does all this technical data mean for you in your grow room or garden? It translates into tangible results that make your life easier and your sessions better.

First, you'll spend less time worrying and waiting. That shorter flowering period means you can run more cycles per year indoors or harvest before bad autumn weather hits outdoors. The robust growth makes it more forgiving of minor environmental fluctuations. When you finally light up, the payoff is immediate: a clean, energetic rush that sharpens creativity and lifts your mood without the heavy body lock, perfect for daytime use or social gatherings. The flavour is a nostalgic trip for Haze purists—sharp, spicy, and unmistakably classic.

Stages and Monitoring of Haze Special

Quick overview: Regular photoperiod · KC Brains Holland · 6-9 week indoor flowering approx. · Ideal for growers with some experience seeking a fast-finishing sativa.

Safe Start

Germinate in a warm, humid environment (22–25°C). For a strong, stress-free start that promotes explosive root development, consider using a rooting stimulant like Klonagel rooting hormone gel.

• Use the paper towel method or plant directly into a light seedling mix.
• Keep humidity high (70-80%) until the seedling is established.
• Transplant carefully to avoid root shock.

Directed Vegetative Growth

Run an 18/6 light cycle. This plant can stretch, so consider training techniques like LST to manage height and encourage lateral branching.

• Use an airy, well-draining substrate to support healthy root growth.
• Water lightly, allowing the medium to dry slightly between waterings.
• Provide moderate nutrient levels during veg; it's not a heavy feeder early on.

Efficient Flowering Transition & Bloom

Switch lights to 12/12 to induce flowering. Watch for a significant stretch in the first two weeks.

• Lower humidity gradually to 40-50% by mid-flower to prevent mold.
• Ensure excellent air circulation around the developing buds.
• Increase Phosphorus and Potassium levels during peak flowering. A bloom booster like Top Candy can enhance bud density and resin production.
• Support heavy colas with stakes or a SCROG net if needed.

Harvest, Drying, and Curing

Harvest when trichomes are mostly milky with some amber, depending on your preferred effect (more amber for a more relaxing finish).

• Flush with plain water for the last 7-10 days.
• Dry slowly in a dark environment at 18-22°C and 50-60% RH for 10-14 days.
• Cure in airtight jars for a minimum of 2-4 weeks, burping regularly, to smooth out the smoke and intensify the flavour.

Frequently Asked Questions

Is Haze Special suitable for beginners?

It's rated as medium difficulty. While its fast flowering and good mold resistance are forgiving, its sativa structure and potential height require some attention to training and environment. A beginner with good research can succeed, but it's ideal for growers with one or two cycles under their belt.

How does it handle humidity and mold?

User reports and its genetic background suggest it has decent resistance to fungal issues, especially for a sativa. However, maintaining good airflow and lowering humidity during the final flowering weeks is always crucial to prevent bud rot.

Can I grow it in a small indoor tent?

Yes, but you'll need to manage its height. Employing Low-Stress Training (LST) early in vegetation, topping, or using a SCROG net are highly recommended to control the stretch and create an even canopy, maximizing your light usage in a limited space.

What's the main difference between Haze Special and a pure Haze?

The most significant difference is flowering time. Pure Hazes can take 14+ weeks, while Haze Special finishes in roughly half that time. The effect and flavour profile remain distinctly Haze-like, but the plant structure is often sturdier and more manageable thanks to its KC 606 heritage.

Personal Experience of Pevgrow's CEO (Alan)

I've run Haze Special a few times over the years, both indoors and in a greenhouse, and it consistently impresses me. It's my go-to recommendation when someone asks for a "real" Haze experience but doesn't have a season to spare. Indoors, under a 600W HPS, it stayed around 1.20 m (3.94 ft) with some LST and yielded just over 300 g (10.58 oz) of solid, spear-shaped colas. The stretch during the first two weeks of flower is real, so be ready to tie branches down.

The smell during the grow is a dead giveaway—that sharp, spicy, almost metallic Haze aroma that fills the room. It's not overly sweet or fruity; it's classic and unmistakable. Compared to longer-flowering Hazes, it feels more vigorous and less finicky. I've found it responds well to a simple nutrient schedule; it's not a nutrient hog. I prefer to harvest when the trichomes are mostly cloudy for that bright, cerebral effect—perfect for a creative afternoon. If you let it go longer with more amber, it takes on a more relaxed edge. For me, the magic is in that speedy finish. You get all the prestige of growing a Haze, but you're trimming buds while others are still waiting for their plants to stop stretching.
