Silver Haze XXL Auto

More about Silver Haze XXL Auto

Silver Haze XXL Auto is the result of some serious breeding efforts by Growers Choice. They manage to capture the cerebral high of classic Haze while lowering down its famously long grow time and strict growth requirements. Silver Haze auto Growers Choice is a strain that hits just like the original, but fits into almost any grow calendar. It was created through crossbreeding of multiple parent strains; let’s take a quick look:

Haze

If you’ve ever had a high that feels like sunshine in your brain, chances are you’ve smoked Haze. Born from a mix of Mexican, Thai, and Colombian landraces strains, Haze is the OG strain when it comes to sativas. It’s known for its long flowering time and even longer-lasting head buzz with lots of energy, creativity, and uplift. It also passes down the classic tall, open-branching structure you’ll spot in Silver Haze XXL Auto.

Northern Lights #5 / Skunk #1

To balance out Haze’s strong energy, Growers Choice chose some heavy hitters from the 1980s: the Northern Lights #5 and Skunk #1 strain. These genetics beef up the structure and resin production in Silver Haze XXL Auto, while shortening the flowering time and helping it grow in indoor setups.

Ruderalis genetics

The Ruderalis genetics are the secret behind every autoflowering cannabis seed. It doesn’t bring much in terms of flavor or effect, but Ruderalis plays a huge role in convenience. It lets Silver Haze XXL Auto flower by itself, regardless of the light cycle. That means no need to flip your lights indoors or stress over outdoor daylight hours.
