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
      A fast grower. HIGHLY RESISTANT to stress. A potent bud, I mean a REALLY potent bud.
    • Disadvantages
      She has a pleasant smell, but it’s way too heavy during the flowering … The carbon filter didn’t help so I was I was sort of on display until harvesting)) xD
    • General impressions

      It was my first grow and I made a lot of mistakes)) However, despite the hellish growing conditions in my 40x40x80 grow box, all plants survived and harvested! I grew 3 different strains in the microbox, temperature varied  from 18 to 33C, lighting - 120W, 20% humidity. I had to prune her all the time as the space in the box was limited. Despite all these factors, this girl rewarded me with 15g of amazing buds just in 12 weeks. I am amazed with her fragrant, delicious and EXTREMELY PSYCHOACTIVE. I not kidding about her potency - she’s really a nut job! I not a first-time user but even for me it was a mind-bending experience! I do recommend her!

      Dry mouth only
    • General impressions

      This is some of the most tasty weed I've ever tried! I don't even really like mango flavor. But this stuff is sweet, and delicious! The effect is what I describe as 'comfy'. It just puts me into an immediate good mood, making it hard to wipe the smile from my face. All around, I am more than pleased with my first ever harvest! So glad I went with Green Crack Auto!

    • Advantages
      Great strain to grow and smoke. Legendary. I’m glad I grew this strain, I liked the fruity aroma and taste!
    • Disadvantages
      None
    • General impressions

      It was rough towards the end, but she rewarded me. 186 grams. 6.6 ounces almost, shattering my previous record of 5.5. I'm very pleased. Really believe in the top-down defoliation strategy in early flower now because I only had 3 grams of larf. These results end the debate. You just have to give her enough time to fill out after the defoliation by being patient about the harvest.

    • Advantages
      All seeds have sprouted. I kept them on cotton pads within 2 days and they split so quickly)) Then I planted them in the BioBizz Light Mix substrate. Vegetation took 32 days. Lighting: 250W HPS during veg. + added 400W HPS during the flowering. Didn’t cause any troubles.
    • Disadvantages
      None.
