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 Fast Buds’ 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.

Green Crack Auto Seeds

Since they first became available for sale, Green Crack Auto seeds have been a huge hit, as this autoflowering strain produces bountiful harvests in just 2 months from seed.

    • Advantages
      My 4 plants yielded over a pound of the best quality cannabis I've ever grown and that's why Fast Buds Green Crack gets a perfect 5/5 stars from me.
    • Disadvantages
      Nothing
    • General impressions

      I love Fast Buds Green Crack... and so do all my friends! I've already given away so much of this crop and it hasn't even finished curing. These 4 plants were just perfect for the majority of this grow. Topped off at 2-3 weeks, this strain will produce many branches with tight internodal spacing. The buds will grow together to form nice tight buds on each branch if enough light is applied to the canopy of the plant.
      The smell of this strain upon harvest is 100% pure pink grapefruit and remains solid throughout the cure. Lots of resin with the Green Crack, probably a good strain for those looking to make rosin etc. The effect of this cannabis is truly worthy of its name and reputation. It is a strong smoke with the best characteristics of a Sativa and an Indica for your enjoyment - Hitting hard and fast without the racing heartbeat and "I'm going green, need to lay down" effect.
      The flavor is reminiscent of the old-school "hydroponic" weed that became popular in the late 80s and early 90s. It's a full-bodied taste with hints of pine and citrus - really smooth in a joint or vape. My husband is a long-time smoker with a pretty high THC tolerance and he wanted a strain that would really get him high again. Green Crack managed to accomplish that task and more, so I wouldn't recommend this strain to beginners or novice smokers. Definitely more of an evening/weekend smoke and an absolute favorite that I will grow again and again!

      Awesome strain! Only 2 out of 3 seeds germinated but I'm not upset at all. Its effect is amazing! I'm not sure about daytime use)). It starts as an energizing Sativa and after about an hour turns into a relaxing Indica... I wish I hadn't tried it at work))

    • Advantages
      Still my biggest car and my favorite crop too... Lots of sugar coated buds...
    • Disadvantages
      Nothing
    • General impressions

      The effects of this Green Crack made me more talkative (and faster), more energetic and I had a lot of creative thoughts... I smoked it in the morning, afternoon and evening (and I never slept)... The cultivation was easy, although I had problems with falling during a period that I never understood.
