Autoflowering seeds
by Azarius
Bruce Banner Auto seeds produce a sativa-dominant autoflower that hits 21–26% THC and finishes in just 8–10 weeks from seed. Born from a cross of OG Kush, Strawberry Diesel, and Ruderalis, this strain packs serious potency into a fast, no-fuss growing cycle. You get the cerebral energy and focus of a premium sativa without ever touching a light timer. That is the pitch, and it genuinely delivers.
Bruce Banner Auto seeds come in 4 available pack sizes — 1, 3, 5, and 10 seeds — so you can match your order to your experience and setup. Grabbing a single seed makes sense if you want to test the genetics in your particular environment before scaling up. The 3-pack suits growers running a small tent who want a uniform canopy without surplus. Start with the 5-seed pack if you are dialling in your grow space for the first time; it gives you enough margin for germination testing without committing to a full 10-pack. The 10-seed pack is your best shout for perpetual harvests or outdoor plots where you want multiple phenotypes to compare.

Round out your Bruce Banner Auto grow with a scrog training net to manage the sativa stretch, a full-spectrum LED panel for maximum resin production, and a carbon filter to keep that diesel funk contained. Pair these three and your setup is sorted from seed to chop.
Photoperiod sativas are brilliant — until they are not. You spend weeks babying a plant through veg, flip to 12/12, and then wait another 10–14 weeks while the thing stretches into your extraction fan. Meanwhile, your electricity bill climbs, your tent schedule locks up, and any light leak during dark hours risks hermaphrodite stress. The consequence is real: delayed harvests, wasted vertical space, and a single crop where you could have pulled two.
Bruce Banner Auto seeds sidestep all of that. Ruderalis genetics trigger flowering based on plant age, not light cycle, so you run an 18/6 or 20/4 schedule from germination to harvest. The entire cycle wraps in 8–10 weeks. In that compressed window, indoor growers regularly pull up to 600 g/m², and outdoor plants in warm climates push towards 700 g/plant. That is photoperiod-level weight on an autoflower timeline.
We have been selling seeds from our Amsterdam shop since 1999, and we have watched first-time growers overcomplicate light timers with photoperiod strains, only to switch to autoflowers like Bruce Banner and cut their setup stress in half. It is one of the most common stories we hear at the counter. And the end product does not compromise — cracking a cured bud releases a sharp, fuel-forward diesel punch that softens into sweet, loamy earth on the exhale. At 21–26% THC, the effect is immediate: an energetic lift that settles into relaxed focus rather than foggy sedation. If you want a heavier, couch-lock indica autoflower, we would steer you toward Northern Lights Auto. But for daytime clarity and a faster finish, Bruce Banner Auto seeds win.
Bruce Banner Auto seeds carry 3 core parent genetics that each pull their weight. OG Kush provides the resinous, fuel-soaked backbone — it is the reason your fingers stick to the scissors at trim time and the reason the THC ceiling sits at 21–26%. Strawberry Diesel adds a sweet, berry-laced counterpoint and contributes the energetic, upbeat side of the effect profile. Ruderalis rounds it out with autoflowering capability, removing the photoperiod dependency so the plant flowers on its own clock.
The terpene expression lands squarely in diesel-earthy-sweet territory. Myrcene drives the loamy, herbal base. Caryophyllene adds a peppery bite that sharpens the diesel notes inherited from both OG Kush and Strawberry Diesel. Limonene floats underneath, contributing a citrus-adjacent sweetness that becomes more pronounced after a proper two-week cure. The combined profile is assertive — this is not a subtle, floral smoke. It announces itself the moment you open the jar, and the flavour holds from the first draw to the last.
Because this is a sativa-dominant autoflower, the reported effects lean toward energetic focus and elevated mood rather than heavy sedation. Users consistently describe a clear-headed buzz that supports creativity and conversation, with a gentle physical relaxation that builds over time without pulling you to the sofa.
Indoors, Bruce Banner Auto seeds perform best under full-spectrum LEDs on an 18/6 or 20/4 light schedule. Expect the vegetative phase to last roughly 3–4 weeks before the plant transitions to flower on its own. From there, flowering runs another 5–6 weeks, putting total seed-to-harvest time at 8–10 weeks. Indoor yields regularly hit 500–600 g/m² when plants receive consistent light, moderate feeding, and good airflow.
Outdoors, the same timeline applies, though warm climates with long daylight hours can push yields up to 700 g/plant. Plant after the last frost and ensure at least 15 hours of direct sunlight daily during veg for the best results. Keep the ambient temperature in the 15–25°C range during early growth for strong root development.
One honest heads-up: the sativa-dominant structure means significant vertical stretch during weeks 3–5 of flower. You will need to plan for a taller tent or use low-stress training early to keep the canopy flat. Topping is possible but riskier with autoflowers because recovery time eats into a fixed lifecycle. Stick to LST and leaf tucking to manage height without sacrificing yield. Nutrient pacing matters too — start light, ramp up through mid-flower, and flush for the final week to keep that diesel-sweet flavour clean.
No. The Ruderalis genetics in Bruce Banner Auto seeds trigger flowering based on plant age, not photoperiod. You can run an 18/6 or 20/4 light schedule from seed to harvest without ever switching to 12/12. This simplifies the entire grow cycle and removes the risk of light-leak stress.
Expect a fuel-forward diesel opening that settles into loamy earth, finishing with a subtle strawberry-sweet exhale from its Strawberry Diesel lineage. A two-week cure in sealed jars brings out the sweetness more prominently and smooths the smoke.
Indoor setups regularly hit 500–600 g/m² under full-spectrum LEDs with proper training. Outdoor plants in warm climates can push 600–700 g/plant. Results depend on light quality, nutrients, and training — but Bruce Banner Auto seeds are among the heavier-yielding autoflowers available.
Yes. The autoflowering trait removes light-schedule guesswork, and the strain tolerates minor nutrient fluctuations better than finicky photoperiod sativas. Start with a 5-seed pack to give yourself room for germination testing while learning the basics.
Keep Bruce Banner Auto seeds in an opaque, airtight container in a cool, dry place. A fridge set to 4–8°C is ideal. This maintains germination viability for months. Avoid temperature swings and moisture exposure, which degrade seed quality over time.
