Auto White Widow XXL 00 Seeds – High-Yielding Autoflowering Indica Hybrid for Easy Growing & Big Harvests

Auto White Widow XXL from 00 Seeds is a high-performance autoflowering indica hybrid that delivers heavy, resinous buds in just 75 to 85 days, making it a top choice for growers who want big yields without the wait.

Are you tired of weak autoflowers that barely fill a jar?

Let’s be real: not all autoflowering seeds live up to the hype. Some promise big harvests but deliver scraggly plants with airy buds and barely enough resin to spark a session. You end up wasting time, space, and nutrients on underperformers that don’t justify their spot under your lights.

What if your grow cycle felt like a waste every time?

Imagine putting in weeks of care—watering, feeding, trimming—only to harvest a few grams of low-density flowers. That frustration adds up, especially when you're counting on quality for your own use or to stretch your supply. The real cost isn’t just in seeds or electricity—it’s in lost time and missed potential every single grow.

Auto White Widow XXL delivers where others fall short

This isn’t your average autoflower. Bred from legendary White Widow genetics and upgraded for performance, Auto White Widow XXL packs dense, resin-coated buds, a fast 75–85 day cycle, and yields up to 600 g/m² indoors or 200 g per plant outdoors. With 16% THC, a citrus-woody aroma, and a deeply relaxing body effect, it’s built for growers who want quality, speed, and consistency—without needing advanced skills.

What you get from Auto White Widow XXL in your daily grow

From the moment it sprouts, this strain shows vigor. It grows fast, stays manageable, and rewards you with heavy harvests of fragrant, trichome-rich flowers. Whether you're growing in a stealth tent or a full indoor setup, you’ll enjoy a low-maintenance grow with high returns. The compact structure fits perfectly in tight spaces, and the minimal stretch means you won’t lose precious canopy height. Plus, the aroma develops early, filling your grow room with a fresh, citrusy punch that tells you good things are coming.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested a lot of autoflowers, but Auto White Widow XXL stands out for its balance of speed, yield, and quality. I grew it in a 1.2 x 1.2 m tent with a 600W LED, 9 plants in 20L pots.
