Text:  This is my 7th grow utilizing the HeyAbby machine. In the past I have struggled finding seeds that didn't grow to tall, even with LST, etc. Not to mention weak potency issues. Z Up it THE best I have found! This strain allowed me to check both boxes. I mean this strain rocks! Super sticky buds that fills my house with awesome aroma and has beautiful tricombs. The plant IS short with a large canopy. I purchased this strain from Seedsman and will order a handful today as I am getting close to harvest and I want more!!

Effect description
Energetic
Z-Up Auto Feminised Seeds are versatile, offering high THC content and impressive yields. Known for vibrant colours, robust structure and appealing fruity-citrus flavour profile.

Z-Up Auto is a vibrant, citrus-packed sativa-dominant hybrid that reinvents lime soda flavor with a bold, exotic twist.

Boasting an extraordinary terpene profile unlike anything else on the market, this strain delivers a zesty fusion of tangy lime, sweet lemon, and a sharp sour kick—like sipping an ice-cold sparkling lime soda on a hot day. Add in sky-high THC levels up to 29%, and you've got a refreshingly potent autoflower that hits fast and lasts long.

Perfect for daytime use or a morning pick-me-up, Z-Up Auto offers a bright, energetic high that uplifts the mood, sparks motivation, and keeps you dialed in without feeling overwhelmed—making it a prime choice for creative sessions or active days.

From a grower’s perspective, she’s a dream when treated right. Z-Up thrives in warm climates and responds well to low-stress training and light defoliation, especially to manage her 70–120cm height. Indoors, she delivers 450–600g/m², while outdoor growers can expect up to 300g/plant of dense, resinous buds gleaming with bright orange pistils and thick trichome coverage.

Keep temps steady between 22–28°C to bring out the best in her flavor and resin output. While her sativa traits may require a bit more attention, her eye-catching results and next-level flavor are more than worth it.

With its soda-pop punch, sticky green buds, and powerfully uplifting effects, Z-Up Auto is a fresh twist on citrus cannabis—ideal for growers who want something fun, flavorful, and full of fizz.
