With 20% THC and a name like that, it’s clear that Green Crack Auto is all about the mental and physical stimulation – focus, clarity, motivation, and tons of creative ideas. This strain is perfect for when you want to get things done and then just chill, after the initial Sativa energy is replaced by a deep, happy relaxation. This is the best strain to begin your daily 4:20 smoking session, or to get that final surge of energy to finish work before commuting back home.

Description

Green Crack Auto Strain Info

Green Crack Auto from Fast Buds is yet another feminized autoflowering version of a legendary and classic American cannabis strain. Fast Buds breeders really hit the jackpot with this easy-to-grow weed that has killer potency and brings in oversized yields.

Genetics

This famous American variety, Green Crack Auto, carries the legacy of Skunk #1 and a choice phenotype of an Afghani Indica. To make it flower automatically, Fast Buds have crossed this legend with their best Ruderalis genetics. However, the resulting auto is the same as its photoperiod parent, leaning hugely to the Sativa side of the spectrum.

Effects

The effects are what we usually associate with Sativa-dominant strains: energetic and uplifting, leaving you happy, focused, clear-headed, and creative for 1.5-2 hours. After that, be sure to find a place to park your butt, because this is when the Indica side with its euphoric relaxation comes into play.

THC Levels

This strain is definitely more for experienced users, because the crazy percentage of THC (20%) will make the high a rollercoaster ride for a beginner or when you accidentally overindulge. Green Crack Auto is a highly potent bud with psychedelic potential, although its CBD content, testing at 0.7%, ensures that the effects don’t cause paranoia.

Smell And Taste

The aromas and flavors are sweet and citrusy with earthy undertones. The presence of myrcene, pinene, and probably other terpenes also makes some Green Crack Auto phenos redolent of mangos.

Yields

This is another aspect where this strain shines. Though easy to grow, these plants routinely produce XXL harvests of up to 650g/m² (2.1oz/ft2) indoors, while outdoors, yields of 300g (10.6oz) per plant are quite possible.

Flowering Time

Green Crack Auto is among the faster-flowering varieties in FastBuds’ collection, usually finishing in an incredible 8 weeks from seed.

Good to Know

A very rapid grower, Green Crack Auto stays quite short (60-90cm or 2’4”-2’11”). Due to its Sativa dominance, slightly warmer and more humid environments will yield the best results. Although it can handle most environmental factors, because of its Ruderalis genes, it’s best grown indoors with HID lightning.

  • Plants respond well to most low-stress training methods as well as defoliation.
  • It’s hungry for fertilizers.
  • The strain is resilient to stress.
  • Because of the potent smell during flowering, carbon filters are required.

      Average yield of highly psychoactive buds)). She got my heart pumping like no other strain! Her stimulating effect is replaced by a smooth relaxation an hour after you try her. In total, the effect lasts 2-3 hours. She makes you very hungry, full of energy and enthusiasm - more than enough to get any creative stuff done.
