How to Grow 2046 Fast Version
2046 Fast Version is a rare thing: a soaring haze sativa that finishes fast. It carries a high 20–26% THC, a clean earthy and woody flavour, and a euphoric, happy, relaxed effect on a tall, vigorous plant that races through bloom in 8–10 weeks instead of the long wait a classic haze usually demands.
Built from Neville’s Haze crossed with a fast-flowering parent, this is an 80% sativa, 20% indica strain with elite haze genetics and a quick turnaround. The result is a tall, resinous, high-THC plant that keeps the energetic, cerebral character of its famous parent while cutting weeks off the harvest.

A Fast-Flowering Haze
The appeal of 2046 Fast Version is simple: it brings classic haze quality without the famous haze waiting game. Pure hazes like Neville’s Haze are legendary for their soaring, cerebral high but notorious for twelve-to-fourteen-week blooms, which puts a lot of growers off.
By crossing Neville’s Haze with a fast-flowering parent, 2046 Fast Version keeps that energetic, euphoric character and high THC while trimming bloom to around 8–10 weeks. You get the haze experience on a far more practical timeline, which is exactly why a Fast Version of this strain exists.
Climate and Where to Grow It
2046 Fast Version suits a temperate climate with plenty of light and good airflow, in line with its sativa heritage. It is a vigorous, adaptable plant that performs both outdoors in a warm season and in a controlled indoor tent, though you should plan for its height, since it stretches tall like a true haze.
Outdoors its fast genetics let it finish across most of the season, with a single plant bringing in a strong 500–650 g in a good spot. Indoors it produces an impressive 450–600 g/m². Keep airflow moving and manage humidity as the long, resinous colas fill in, since tall sativa structures benefit from open, well-ventilated canopies.
Indoors, aim for daytime temperatures around 72–82°F (22–28°C) and keep steady air circulation through the tall canopy. Its height is the main thing to plan for: give it vertical headroom, or start low-stress training early to spread the plant out and keep every bud site in good light.
Growing Fast Version Seeds
It is worth being clear: 2046 Fast Version is not an autoflower. It is a photoperiod plant that simply blooms faster than usual. Grow it under a long day (around 18 hours of light) through the vegetative stage, then switch to a 12/12 light cycle to trigger flowering, just as you would with any photoperiod strain.
The difference is speed. Once you flip to 12/12, the fast genetics push this haze through bloom in roughly 8–10 weeks, where a pure Neville’s Haze might need twelve to fourteen. A longer veg builds a bigger frame and harvest, while a shorter veg helps keep this naturally tall plant more manageable before the flip.
Feeding Schedule (EC Guide)
This is a vigorous, hungry sativa that packs on long, resinous colas, so you can feed it steadily through bloom. Start low, build up as the plant asks for more, and taper off for the final flush so the clean earthy, woody flavour stays bright and the smoke finishes smooth.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the long colas swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs a fast 8–10 weeks. As an 80% sativa, it stretches hard early in bloom, then fills in long, spear-shaped colas rather than the dense, chunky buds of an indica, staying airy and resin-flecked right to the finish.
Give the tall structure support as the colas gain weight, and keep the canopy open so light reaches the lower flowers. Harvest when most trichomes have turned cloudy with a few amber heads for the fullest expression, and run a short plain-water flush in the last week or two before you cut it down.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. A slow, even dry preserves the earthy, woody terpenes and the airy bud structure, which can degrade quickly if the flowers are dried too hard or too fast.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the woody depth and fresh, piney notes forward and smooths the smoke, which is exactly what this fast-flowering haze deserves after its quick finish.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. 2046 Fast Version is a resinous, high-THC plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of potent, haze-flavoured concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
2046 Fast Version has a clean, earthy and woody flavour with a fresh, pine-like edge, a grounded, savoury profile rather than a sweet or fruity one. It is the kind of classic, incense-like haze taste that carries well through a careful cure and suits its cerebral, uplifting character.
It carries a broad, layered terpene stack, and the ones that shape the flavour stand out clearly. Myrcene and humulene carry the earthy depth; pinene adds the woody, pine-like freshness; caryophyllene folds in a gentle peppery spice; borneol grounds it with an earthy, camphor note; and eucalyptol lends a cool, fresh lift. A supporting cast of phellandrene, phytol and valencene fills in the aromatic corners.
Effects and Best Use
With its heavily sativa genetics, 2046 Fast Version is reported as euphoric, happy and relaxed, an energetic, cerebral lift carried straight over from its Neville’s Haze parent. It leans toward daytime and creative use, giving an uplifting, feel-good high with just enough body to keep it comfortable.
At a potent 20–26% THC it hits hard for a sativa, so a little goes a long way, especially for less experienced users. That strength, the fast 8–10 week finish, the strong yield and the classic haze character are exactly why growers reach for this Fast Version.
FAQ
Is 2046 Fast Version an autoflower?
No. 2046 Fast Version is a fast-flowering photoperiod plant, not an autoflower. It still flowers when you switch the lights to 12/12, but its fast genetics shorten bloom to around 8–10 weeks, which is remarkably quick for a Neville’s Haze sativa and gives you an auto-like turnaround with full photoperiod control.
How long does 2046 Fast Version take to flower?
Once you flip to a 12/12 light cycle, bloom runs about 8–10 weeks, which is extremely fast for a haze. Classic Neville’s Haze can take twelve to fourteen weeks, so this Fast Version cuts weeks off that wait while keeping the soaring, sativa-forward character its parent is famous for.
Is 2046 Fast Version indica or sativa?
It is strongly sativa-dominant, at roughly 80% sativa and 20% indica, which it inherits from its Neville’s Haze side. That shows in a tall, stretchy plant and an energetic, euphoric, happy lift, with just enough indica to keep the effect relaxed and comfortable rather than purely racy.
Is 2046 Fast Version good for beginners?
Yes. Its biggest beginner advantage is speed: a fast 8–10 week bloom means less time exposed to problems than a normal haze. Plan for its height, since it stretches tall like a sativa, so give it headroom or start low-stress training early, and it is a rewarding, high-THC grow.
What does 2046 Fast Version taste like?
Expect a clean, earthy and woody flavour with a fresh, pine-like edge, a grounded profile rather than a sweet or fruity one. Myrcene and humulene carry the earthy depth, pinene adds the woody-pine freshness, caryophyllene brings a gentle peppery spice, and eucalyptol lends a cool, camphor-like lift.
How tall does 2046 Fast Version grow?
It reaches around 4.92 ft (1.5 m), tall and stretchy in line with its sativa, haze-heavy genetics. Indoors that stretch is worth planning for with headroom or early training, while outdoors the height helps it bring in a strong crop, so treat the extra size as part of its yield potential.
