Sensi Supreme Oak Autoflowering Seeds – Sensi Seeds | F1 Hybrid, Fast 55–65 Day Flowering, XL Yields

Sensi Supreme Oak Autoflowering Seeds from Sensi Seeds deliver XL yields of up to 350 g/m² in just 55–65 days, thanks to their stable F1 hybrid genetics and powerful 25% THC content.

Are you tired of waiting months for a harvest?

Most autoflowering strains leave you choosing between speed and potency, compact size and yield. You end up with plants that grow too tall, smell too strong, or take forever to finish — wasting time, space, and energy. And if you're growing in a colder or unpredictable climate, mold and pests can wipe out your crop before it even matures.

That constant stress kills the joy of growing. You’re not just losing buds — you’re losing confidence.

Meet Sensi Supreme Oak Autoflowering — the F1 hybrid that ends the compromise. Bred by Sensi Seeds with elite genetics from Jack Herer, Shiva Skunk, and Northern Lights #5 x Haze, this strain delivers massive yields in record time, all while staying under 75 cm (29.53 in) tall. Its natural resistance to mold and pests means fewer worries, and the 25% THC ensures a strong, balanced high that starts cerebral and eases into a relaxing body buzz — perfect for daytime creativity or winding down without sedation.

Before growing with Sensi Supreme Oak

Setting up for success starts with the right foundation. These seeds thrive when given a stable, low-stress start. Because they’re autoflowering, you won’t need to adjust light cycles — just keep them under 18–20 hours of light from day one. Choose a final pot of 18–27 L (6.76–10.17 gal) to avoid transplant shock, and use a well-aerated soil mix rich in organic matter.

• Start seeds in a warm, humid environment (22–25 °C / 71.6–77 °F)
• Use a final pot from the beginning — no repotting needed
• Choose light, airy soil or coco for strong root development
• Keep pH between 6.0–6.5 (soil) or 5.8–6.2 (coco)
• Prevent deficiencies with a balanced nutrient starter

During growth: watch it thrive

Sensi Supreme Oak grows fast and stays compact, rarely exceeding 75 cm (29.53 in) indoors. It develops a dense, bushy structure with tight internodal spacing and a dominant central cola. You’ll notice a fresh pine aroma early on, evolving into zesty citrus and spicy musk as flowering kicks in. While it responds well to light training like LST, avoid topping or aggressive pruning — this is an autoflower, after all.

For sustained growth, Top Veg keeps your plant green and balanced without overloading it with nitrogen. Its compact size makes it perfect for SOG (Sea of Green) setups, and its resilience shines in cooler climates where other strains would struggle.

After harvest: enjoy the rewards

After just 55–65 days, you’ll be trimming dense, resinous buds with long, slender leaves and a powerful terpene profile. Expect indoor yields of 275–350 g/m² (8.10–10.30 oz/ft²) and outdoor harvests of 225–300 g/plant (7.94–10.58 oz/plant). The effect? A long-lasting, balanced high — uplifting at first, then gently relaxing. And because it’s an F1 hybrid, every plant grows nearly identically, so your results are consistent, grow after grow.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested a lot of autoflowers, but Sensi Supreme Oak stands out. I grew it in my 1.20 m² (12.92 ft²) tent with a 600W LED, 18/6 light cycle, and Mars Hydro air pots. I started with a 20 L (7.48 gal) final pot and used BioBizz nutrients — light but effective. No topping, just gentle LST to spread the canopy. By week 5, the pine-citrus smell was unmistakable. I added K-Boost in week 6 of flowering, and the bud density jumped. Harvested at day 63 — trichomes were 80% milky, 20% amber. Dried for 12 days, cured for 3 weeks. Yield: 312 g (11.01 oz) from a single plant. The high is clean, uplifting, and lasts for hours. No anxiety, no couch-lock. If you want a fast, reliable, high-THC autoflower that actually delivers, this is it.
