The specs in one line: 15-20% THC, <1% CBD, 8-9 weeks from seed flowering, 400-550 g/m² reported. Best indoor or outdoor. easy grow.

Smell-first warning: the diesel and earth coming off Chemdawg Auto at week six will reach neighbours before harvest does, so plan your carbon filtration early. Fast Buds' autoflowering cut wraps up in 8–9 weeks from seed and pulls 400–550 g/m² indoors under a decent light schedule, which is a solid return for a strain that asks very little from the grower — difficulty is rated easy, and it handles both indoor tents and sheltered outdoor spots without much fuss.

THC lands in the 15–20% range, so the effect is heavier than a casual afternoon smoke. Buds come in dense and resinous, which makes them a good candidate for extraction if fresh-frozen is part of your workflow. Canadian growers running short outdoor seasons in Ontario or BC will appreciate the autoflower timeline — you can drop seeds in late May and be done well before the first cold snap.

Best suited to growers who want a no-drama run with punchy, fuel-forward results.
