Diesel Auto takes one of the most recognizable American flavors and puts it into a faster, simpler package. Descended from New York City Diesel, she carries the sharp, fuel-like character that made the original famous, while her Lowryder #2 heritage supplies the automatic flowering trait.

Her genetic makeup is 40% sativa / 30% indica / 30% ruderalis. That blend keeps the effect well-rounded and gives her the toughness and speed of ruderalis, without losing the bright NYCD personality.

Diesel Auto runs from germination to harvest in about 90–95 days, or 13 to 13.5 weeks. Because she flowers based on age, there is no need for a 12/12 switch. Leave the lights on 18/6 or 20/4 and she will handle the transition herself.

She is genuinely small. Indoor plants usually stay at just 1 to 2 feet (30–60 cm), ideal for micro tents, cupboards, and other tight spaces. Outdoors she can reach 2 to 4 feet (60–120 cm), and her low profile helps her stay discreet in the garden.

Flavor and Effects: Fuel, Citrus, and a Clear Head

The flavor is classic Diesel: chemical, fuel-like, and sharp on the inhale. Compared with photoperiod NYCD, the diesel edge is a little softer, which makes the smoke more approachable. Behind the fuel, bright citrus and fruity notes add balance and keep each draw from feeling too dense.

The high mirrors the clean character of the original. Royal Queen Seeds describes it as calming and clear: a level, relaxed mood without a cloudy or heavy finish. That makes Diesel Auto a good companion for daytime sessions, light chores, or a calm conversation.

With up to 14% THC, she offers a manageable strength that suits smokers who want flavor and function over sheer power.

Growing Diesel Auto Seeds

Diesel Auto is low-maintenance and forgiving. Indoors, she can produce 11 to 13 oz/m² (310–370 g/m²) of dry buds under good conditions. Gentle LST can open up the canopy, but she generally performs well with minimal interference.

Outdoors, each plant can yield 2 to 4 oz (60–110 g). Give her more root space and strong sunlight to help her reach the upper end of her range. She thrives in regions with long, warm summers.

Odor control deserves attention. As the flowers mature, Diesel Auto develops a strong, fuel-rich scent. Use a carbon filter indoors, dry and cure carefully, and choose plant locations thoughtfully outdoors.
