Cultivation manual

Mack and Crack© Autoflower seeds genetics: Mack and Crack© × Green Crack Auto

Mack and Crack© FeminizedXGreen Crack Autoflower→ Mack and Crack© Autoflower

Mack and Crack© derives from an insane combination of genetics that starts with a crazy variety that's lucky to exist: The MAC. Also known as Miracle Alien Cookies, this cannabis strain started with a cross of Starfighter with some special Colombian genetics. Long story short, those seeds went through a hell of a journey until only one of them germinated to become a male. The male was used to pollinate a female Alien Cookies, a variety that originates from the crossing of Alien Dawg and Girl Scout Cookies (which is a royal pedigree crossing in itself). Miracle Alien Cookies was then crossed with Green Crack to produce Mack and Crack© (Green Crack is a classic cannabis strain from the US East Coast known for her super fast flowering and relatively potent buds that ooze sweet and skunky aromas and flavours).

Mack and Crack© Autoflower aroma and flavour: diesel, cream and berries

CitrusHerbal

FLAVOUR

Mack and Crack© emits a very Diesely flavour with creamy touches. It is a refreshing funk that has just enough of the cream and berry flavours to add a bit of sweetness to what is otherwise a very skunky experience.

AROMA

As Mack and Crack© matures and produces flowers, she develops a robustly sweet and creamy aroma. As she gets towards the end of the flowering, a deep berry fragrance starts to fuse with the creamy smell, giving off a scent that is reminiscent of a freshly baked pie.

As the buds dry, unmistakable Diesel aromas begin to take centre stage. While trimming Mack and Crack©, the characteristic garbage aromas of Sour Diesel are ever present, enhanced by the still creamy and sweet undertones.

Mack and Crack© Autoflower effects and THC: a powerful experience

Mack and Crack© Autoflower phenotypes, morphology and yield

Mack and Crack© expresses a variety of phenotypes, spanning the spectrum between sativa-leaning and indica-dominant hybrids. Three out of six plants expressed lots of stretching in the flowering stage, whereas only one was incredibly short and squat, with the remaining two somewhere in between. There was a particularly special phenotype that expressed short and dense growth patterns and over-sized calyxes that were totally covered in snowy-white trichomes. Generally speaking, Mack and Crack© produces lots of sweet, skunky, and creamy flavours and smells, with each pheno showcasing a unique combination of all of them.

Three out of the six phenotypes expressed a lot of stretching, as well as lateral branching, meaning that they took up a large footprint while also being up to one metre in height. While these three plants were the widest and stretchiest, with the largest internodal spacing, they were also by far the largest yielders.

Some Mack and Crack©'s phenotypes develop various purple tones, but, overall, they have a beautiful bright green colour. The longer-flowering phenotype has a very tropical green colour, with tons of thin, red pistils. Because of the premium buds that this genetic produces, anyone who's given a bag full of this stuff will be absolutely over the moon!

All plants produced well over 150g; one phenotype in particular (the widest specimen, that was also rather stretchy and tall) was struggling to maintain the weight of her buds, and finally produced 300g. It is safe to say that Mack and Crack© is a heavy yielder with the capability to produce some exceptionally large buds.

How to grow Mack and Crack© Autoflower seeds: key tips

Mack and Crack© is an extremely easy and forgiving genetic to propagate. It happily takes lots of nutrients but doesn't demand huge amounts. Her excess foliage is the only thing that must be taken care of to ensure that she matures to her maximum potential.

Mack and Crack© takes about 4 to 4 1/2 weeks after germination to start flowering, and during this time she builds a strong, sturdy stalk with mostly long, stretching branches. The Sea of Green or Scrog methods are highly recommended for indoor cultivation to manage the stretching.

While the phenotypes of Mack and Crack© showed different amounts of stretching and therefore developed various sizes, they all started flowering at the same time, at about 4 weeks after germination. While some of the phenos continued to stretch as they flowered, two of them started producing very stacked and thick buds right from the beginning. As well as starting to flower simultaneously, all six plants were also ready for harvest at the same time (85 days after germination), except for one phenotype that needed two extra weeks. This longer flowering pheno also ended up being the sweetest and most pungent of them all. If you want the buds to pack on some extra weight and density, let certain phenotypes go as long as 15 weeks.

These marijuana plants were cultivated in generic 1.8-2-2 potting soil. 1g dolomite lime / litre of soil was used as a source of calcium and magnesium. Although they didn't require any nutrients other than those that were already in the soil during the vegetative phase, these plants accepted all the additional nutrients that they were given. Extra phosphorus and potassium are recommended during the flowering in order to increase yields and boost potency.

Tips to get the best out of her:

  • Outdoors: this cannabis variety is very hearty and, while it produces compact buds, they are not so compact as to invite mould and mildew outdoors. This genetic is a smart choice for outdoor farmers who need a reliable yielder of potent buds to set-and-forget and then come back to when it's harvest time. On the other hand, for the biggest yield, defoliate, defoliate, defoliate!
  • Indoors: indoor farmers will have to be prepared to play Tetris in their grow room to find the most efficient fit for all the different shapes and sizes of these phenotypes.
  • For small growers: defoliation is essential for the larger phenotypes to enable enough light to penetrate the canopy and get to the buds on the inside of the plant. Growers in small environments should be careful not to germinate too many seeds, as some of these phenos might quickly outgrow the space they've been given.

Is she the right choice for you?

✅ YES, if you're looking for...

  • Heavy harvests: every plant yielded over 150 g and one reached 300 g
  • A diesel, skunky flavour with creamy and berry touches
  • A powerful effect that relaxes the body without gluing you to the couch, with high THC (up to 28%)
  • Exclusive genetics from the Seedstockers Superior collection
  • Easy, forgiving autoflower seeds that take nutrients well
  • Growing indoors (SOG or SCROG) or outdoors

❌ NO, if...

  • You don't want to spend time defoliating
  • You want uniform plants: her phenotypes vary a lot in shape and size
  • You grow in a very small space: some phenotypes reach one metre in height
  • You prefer a photoperiod strain: in that case, try Mack and Crack© Feminized

Mack and Crack

As a beginner grower, I was really impressed with Mack and Crack. It was super easy to grow, didn’t need much attention, and gave me great buds. The plant stayed manageable in size and grew fast. The buds turned out dense and frosty, with a strong, uplifting high. Perfect – I’ll definitely grow this one again. Shout out to the Seedstockers team for giving me advise with my first big order.
