Our take
Critical Autoflower combines the heavy-yielding Critical strain with Lowryder's no-fuss autoflowering genetics. At 16% THC, it sits in a comfortable middle range — potent enough to be satisfying, not so strong it overwhelms. The effects lean relaxed and happy with a creative edge, and the earthy, lemon-pine aroma is genuinely pleasant. Rated intermediate, it rewards growers who have one or two harvests under their belt.

Growing notes
This indica-dominant auto stays at a medium height, making it manageable in tents or small outdoor spaces. Indoors or out, the 56–70 day total cycle keeps things moving. Aim for consistent feeding and avoid heavy plant stress techniques, since autoflowers have limited recovery time. Yield potential of 400–500 g/m² indoors is achievable with good light and steady environmental control.
