Critical Neville Haze Early Version – Delicious Seeds Fast Sativa · 45 Days Flowering · 23.5% THC

Critical Neville Haze Early Version by Delicious Seeds is a revolutionary fast-flowering photoperiod strain that delivers a pure, energetic sativa experience in just 45 days of bloom.

Growing pure sativas usually means dealing with endless flowering times, towering plants that demand complex trellising, and a stressful race against the autumn weather.

You end up with an unmanageable jungle in your grow tent, burning electricity for 12 or more weeks, or watching your outdoor crop succumb to mold and cold because it simply wasn't ready before the October rains hit.

This fast version simplifies your entire cultivation process, allowing you to harvest top-tier Haze buds weeks ahead of schedule, reducing risks, saving resources, and keeping your grow room perfectly manageable.

Less waiting, more harvesting

This strain takes the legendary genetics of Critical Neville Haze and crosses them with its autoflowering counterpart to drastically shorten the cycle. You get the 80% sativa dominance you crave, but it behaves with the speed of an indica.

Instead of juggling multiple light schedules or extending your nutrient regimen for months, you can streamline your operation. It grows vigorously but flips to flower and packs on weight rapidly, meaning you get premium, incense-scented buds without the traditional sativa struggle.

What you can simplify in your grow room

Growing this early version changes the game for sativa enthusiasts.

• Electricity bills: Shave weeks off your 12/12 lighting cycle.
• Pest control: Harvest before late-season caterpillars and botrytis strike.
• Canopy management: Less time spent super-cropping and tying down runaway branches.
• Nutrient usage: Stop buying extra bottles of late-bloom boosters for extended flowering.
• Weather anxiety: Forget checking the September rain forecast every five minutes.

How to streamline your sativa grow with this seed

1. Review your space: Ensure you have enough vertical room, as it still stretches like a true Haze.
2. Ditch the complex schedules: Stick to a standard 3-week veg and flip to 12/12.
3. Center your setup: Use the SCROG method to maximize light penetration and yield.
4. Optimize your pots: Use 11-liter containers indoors to control the root zone and canopy.
5. Simplify your nutrients: Focus on a solid base like the Top Soil Starter Pack Top Crop and a quality PK booster for the short 45-day window.

Advantages and benefits of a faster cycle

• Fewer decisions: A shorter bloom means less time second-guessing your feeding chart.
• Less maintenance: Fewer weeks of watering, defoliating, and monitoring.
• More clarity: A predictable, rapid finish lets you plan your next run sooner.
• Faster rituals: Enjoy that soaring, creative 23.5% THC high much earlier.

Frequently Asked Questions

Is this strain an autoflower?

No, it is a photoperiod strain. The ruderalis genetics are only used to speed up the flowering time to 45 days, but you still need to switch your lights to 12/12 to trigger bloom indoors.

Can I grow it outdoors in cold climates?

Absolutely. Because it finishes by early September in the Northern Hemisphere, you can harvest massive yields before the cold, rainy autumn weather sets in, making it perfect for shorter summers.

Does it still feel like a pure sativa?

Yes! Despite the fast finish, the effect is highly cerebral, creative, and energetic, with almost no heavy body load. It retains the classic Haze high and incense flavor.

Personal Experience of Pevgrow’s CEO (Alan)

Over the years, I’ve realized that keeping a grow room simple is the secret to longevity in this hobby. I used to run pure sativas that took 14 weeks to flower, requiring endless nutrient tweaks, multiple nets, and a lot of patience. It was rewarding, but exhausting. When I switched to fast versions like this one, my whole perspective changed.

Critical Neville Haze Early Version is now a staple when I want that soaring, creative Haze effect without the logistical nightmare. I pop them in 11-liter pots, veg for just three weeks, and flip. By day 45 of flower, I’m chopping down sticky, incense-smelling colas. My advice? Don't overcomplicate the feeding. Give it a solid base, keep the environment dialed in, and let the fast genetics do the heavy lifting. You get all the sativa magic with half the stress.
