Flowering Time & Yield

Z-Up Auto is a grower’s dream, pumping out some serious XL yields while keeping things relatively easy to manage.

Indoors, expect to harvest around 450–600g/m² (15.8–21.2 oz/ft²) of dense, sticky buds coated in glistening trichomes.

Outdoor growers can pull anywhere between 60–300g (2.1–10.6 oz) per plant, depending on climate and conditions.

She stays fairly compact, reaching heights of 70–120cm (2.3–3.9 ft), making her a solid choice for small grow spaces or stealth setups.

Flowering time? A quick 8 to 9 weeks, meaning you won’t have to wait long before you’re swimming in resin-soaked, citrus-scented goodness.

As soon as you crack open a jar, you’re hit with an intensely tangy, sweet, and sour citrus blast that fills the room with fresh lime and zesty lemon notes.

It’s loud, it’s pungent, and it’s seriously addictive.

Z-Up Auto isn’t just another sativa-dominant hybrid—it’s a full-on sensory experience that takes you higher, faster, and fresher than anything else out there.

Growing Tips & Expert Advice

Z-Up Auto might be easy to grow, but there are a few tricks to really maximize her potential.

Since she leans towards the sativa side, she can stretch quite a bit, so low-stress training (LST) and a bit of defoliation can help keep her under control and improve airflow.

She thrives in warm, sunny climates but also adapts well to indoor setups with stable temperatures between 22-28°C (71-82°F).

Being a light feeder, she doesn’t need heavy doses of nutrients—overfeeding can do more harm than good, so it's best to keep it mild.

Her natural resistance to pests and mold makes her a solid choice for both beginner and experienced growers looking for a hassle-free run.

With the right care, she rewards with rock-hard, resin-dripping buds that look as good as they smoke.

What stands out the most? That mind-blowing terpene profile.

We’ve tried plenty of citrus-heavy strains before, but this one is on a whole different level—it’s pure fizzy lime soda magic.
