Spec sheet first — strain: sativa, seed type: autoflower, THC: 20-25%, yield band: medium, environment: indoor or outdoor.

Smell-first, this one announces itself before the jar is even open — sharp lemon peel layered over diesel funk and a skunky sweetness that catches you off guard. Lemon Haze Autoflower F1 from Blimburn Seeds runs 9–10 weeks seed to harvest, making it a practical choice for Canadian growers squeezing a late-season outdoor run before temperatures drop in September. Indoor yields sit in the 400–500g/m² range under dialled-in conditions, and the cannabinoid panel consistently reads 20–25% THC with negligible CBD — a profile that trends creative and uplifting rather than sedating.

Expect to put in some real work: moderate difficulty means this plant responds noticeably to feeding consistency and light management, so it rewards growers who track their numbers rather than those running a hands-off approach. Both indoor and outdoor environments work, though indoor gives you better control over the outcome. Best suited to intermediate growers comfortable adjusting nutrients through a short, fast-moving cycle.

Indoor Growing: Expect a flowering time of 9-10 weeks with yields of 400-500g/m2. Plants typically reach 60-100cm indoors.
