Ultimate Auto by Dutch Passion

The Ultimate became a Dutch Passion bestseller soon after launch thanks to enormous yields and a strong, long-lasting high. Ultimate Auto carries those genes into autoflowering form by crossing The Ultimate with the classic bestseller Auto Mazar. The result is a robust, forgiving auto with exceptional vigor and an XXL yield rating, widely considered one of the heaviest producers on the market.

Under strong light she fills out with a thick central cola surrounded by 10-20 large side branches, each capable of carrying almost as much bud as the main top. In good conditions she yields 600+ g/m² (1.97+ oz/ft²), and experts can reach up to 1,000 g/m² (3.28 oz/ft²). Several hundred grams per plant are common, and she has a reputation for occasional plants holding up to a kilogram (35.3 oz) of dry bud.

Most plants reach 1-1.5 m (39-59 in), and exceptional specimens approach 2 m (79 in). The seed-to-harvest window is 11-14 weeks with an average of about 12. The biggest phenotypes can throw a second wave of foxtail growth on the colas and deserve a few extra weeks, since these are often the top yielders.

Lemon Aroma and a Long-Lasting High

Like her photoperiod parent, Ultimate Auto smells mainly of citrus and lime, with sweeter, earthy notes appearing during bloom. After drying and a proper cure the lemon comes on even stronger, joined by a musky depth. The taste recalls classic Lemon Haze and Lemon Skunk, and some smokers catch a hint of coffee on the exhale.

The golf-ball-and-bigger buds are fully coated in trichomes and carry an old-school aroma reminiscent of Amsterdam coffee shop culture. That resin load also makes her popular for oil, rosin, shatter and wax.

The high is clear, cerebral and energetic at first, with a strong euphoric opening. It builds gradually as a creeper and lasts for hours. Smoke a little more and it turns calmer and more soothing, with a pleasant urge to stay put for a while.

Growing Ultimate Auto

She is ideal for beginners: forgiving, hard to overwater or overfeed, and happy in soil, coco, hydro, DWC or RDWC. She tolerates 24/0, 20/4, 18/6 or even 12/12 lighting, with 20/4 giving the best results. Build nutrients carefully and ease off when leaf tips turn white or yellow. Large plants drink several liters (well over a gallon) of water per day, so a tensiometer helps fine-tune irrigation.

Use fabric or air-pruning pots for maximum root oxygen, and outdoors choose containers of at least 30-50 L (8-13 gal) or plant directly in the ground. Give her intense light, ideally LED from multiple angles, and support the long, heavy colas with a net or ties.

For outdoor growing, pre-grow for about 2.5 weeks indoors under 20-24 hours of light, then plant out during the sunniest months for several hundred grams per plant. To keep her shorter, top after 3.5-4 weeks or use LST and supercropping to steer growth outward.
