Oldtimer's Haze Regular – Ace Seeds | 100% Sativa Landrace Haze Genetics

Oldtimer's Haze Regular by Ace Seeds is your direct link to the legendary 1970s sativa era — a pure, stabilized 100% sativa that delivers a stimulating, ceilingless high and an authentic old-school aroma of incense, antique wood, and tropical fruit. This isn’t just another Haze — it’s a living archive of nearly lost genetics.

Are you still stuck using modern hybrids that only hint at the magic of true tropical sativas?

Most growers today only scratch the surface of what Haze can be — stuck with fast-flowering, indica-dominant crosses that sacrifice complexity for convenience. You end up with less flavor, weaker effects, and a plant that doesn’t truly represent the legendary lineage.

That limited approach means missing out on the full spectrum of Haze: the deep cerebral buzz, the vibrant terpene profile, and the genetic potential to create next-level hybrids. You’re forced to grow multiple strains to get what one authentic Haze can offer.

Oldtimer’s Haze changes that. This stabilized hybrid of vintage Colombian, Thai, Indian, and Mexican sativas thrives in multiple environments — whether you're cultivating outdoors under the sun, in a greenhouse near the Mediterranean, or running a breeding project indoors. It adapts, performs, and preserves the full depth of flavor and effect that made Haze legendary.

Use Case 1: Outdoor Cultivation in Warm Climates

Picture your Oldtimer’s Haze stretching tall under the sun, thriving in a coastal garden between 20º–37º latitude. With its high resistance to heat and botrytis, this sativa handles humid summers and late-season rains like a pro.

Grow it in rich organic soil mixed with guano and worm castings — keep nutrients low, especially nitrogen — and let it follow its natural rhythm. You’ll be rewarded with willowy colas that blush in reds and purples as winter approaches.

For a strong start, SeedBooster Plus germination stimulator boosts root development and reduces early stress in seedlings.

Use Case 2: Indoor Breeding & Preservation Projects

Inside, Oldtimer’s Haze isn’t for the faint of heart — but it’s pure gold for breeders and preservationists. With its extreme genetic stability and dominance in crosses, it’s ideal for creating new hybrids that carry the true Haze essence.

Use an 11/13 or even 10/14 light cycle to manage its long flowering (14–20 weeks) and prevent re-vegging. Train it with SCROG or LST to maximize lateral growth — this sativa responds vigorously to pruning.

Its low nutrient demand means you can avoid synthetic overfeeding — a clean, minimalist approach that highlights its natural vigor. Pair it with Fish Mix BioBizz for gentle organic feeding that supports steady growth without stretch.

How to Choose the Best Use for You

Oldtimer’s Haze fits different growers — the key is matching it to your goals and environment.

• If you’re a collector or breeder, this is your genetic foundation strain.
• If you grow outdoors in a warm, subtropical climate, it’s a no-brainer.
• If you’re an indoor grower with patience and space, it’s a rewarding challenge.
• If you want fast results or limited space, consider a Haze hybrid instead.

How to grow Oldtimer's Haze Regular

Maximize the potential of this legendary sativa with a tailored approach based on your setup.

Quick overview: Regular 100% sativa from Ace Seeds · 14–20 week flowering · best for outdoor or greenhouse grows in warm climates · high difficulty.

Safe start: Germinate in moist, warm conditions (22–25 °C) with high humidity.

• Use jiffy or starter cubes with SeedBooster Plus for faster rooting
• Transplant when radicle reaches ~1 cm (0.4 in)
• Avoid overwatering — keep medium well-drained
• Place in bright, indirect light until established

Directed growth: Optimize structure early for better yields.

• Use 18/6 light cycle indoors; consider 11/13 to control stretch
• Top or FIM to encourage bushier growth
• Train with LST or SCROG to manage height and expose lower nodes
• Use airy soil mix rich in organic matter — avoid high nitrogen

Flowering by stages: Support long bloom with consistent care.

• Switch to 12/12 (or maintain 11/13) to initiate flowering
• Reduce to 10/14 in late flowering to speed up maturation
• Keep humidity at 40–50% to prevent mold
• Support heavy colas with stakes or netting

Harvest, drying and curing: Patience pays off.

• Harvest when trichomes turn milky to amber (for balanced effect)
• Flush 7–10 days before harvest to improve taste
• Dry slowly at 18–22 °C (64–72 °F) and 50–60% RH
• Cure in jars for 2–4 weeks, burping daily

Frequently Asked Questions

Can I grow Oldtimer’s Haze indoors?

Yes, but it’s challenging. It requires a tall space, long flowering time (14–20 weeks), and careful light management. Best suited for experienced growers or breeding projects.

What climate does Oldtimer’s Haze need outdoors?

It thrives in tropical or subtropical climates (20º–37º latitude). A warm, coastal environment is ideal. In cooler zones, use a greenhouse to extend the season.

Does it need a lot of nutrients?

No — it prefers low to moderate feeding, especially with nitrogen. Overfeeding can harm its delicate growth. Organic soils with guano and compost work best.

Can I use it for breeding?

Absolutely. Its genetic stability and dominant sativa traits make it a powerful parent for creating new Haze-dominant hybrids with authentic flavor and effect.

How tall does it get?

Indoors: 1.20–1.80 m (3.94–5.91 ft). Outdoors: up to 3 m (9.84 ft) in optimal conditions.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Oldtimer’s Haze in my greenhouse near Valencia — a perfect 30º latitude spot. I started five regular seeds, kept the strongest female, and let her go wild. She hit 2.6 m (8.5 ft) and flowered for 18 weeks. The smell? Ancient wood and ripe mango. The high? Clear, endless, and deeply creative — no couch-lock, just pure mental lift. I used minimal feeding — mostly Fish Mix BioBizz and compost — and trained her with SCROG. She resisted late-season humidity like a champ. If you want real Haze, not a remix, this is it. Not for beginners, but for those who value authenticity? Priceless.
