Welcome to the grow report of Break-Up Cake Auto by Kannabia, where we offer a detailed and objective look at the growing process of this marijuana strain in a SCROG setup. Week by week, we’ll keep a watch on how this plant develops through her different stages of growth, providing information about her physical features, nutritional needs, and optimal growing conditions. Without a doubt, this is a complete overview of one of the most fascinating cannabis varieties available in our catalogue.

Break-Up Cake Auto by Kannabia is an autoflowering seed that masterfully combines two champion genetics (Wedding Cake and OG Kush) with a select ruderalis strain. This cross results in a non-photodependent hybrid with 60% indica dominance that is renowned for her high yielding potential, piercing aroma, and extremely easy cultivation.

This plant has a full life cycle of around 70 days from germination to harvest. When grown indoors, she’s characterised by her compact size and incredibly high yields. And she can also produce good crops outdoors, where she’s able to grow a little further if she has enough space. Her flowers are compact and especially resinous, so she’s the ideal choice for various cannabinoid extraction techniques.

In terms of flavours and aromas, Break-Up Cake Auto offers a creamy profile, with complex fruity nuances on an earthy background alongside touches of pine… A true gift for the senses that evokes moments of joy in an autumn forest, but can also be incredibly attractive to those who like the taste of freshly baked pastries.

With a THC content of up to 22%, Break-Up Cake Auto’s effects are balanced, and provide deep physical relaxation and a positive cerebral effect that leads to pleasant mental euphoria. It’s like finding a quiet retreat amid the chaos of everyday life… A place where you can rest from the mundane noise and let yourself be carried away by imagination and creativity.

Not only is Break-Up Cake Auto a delight for the senses but also a symbol of endurance and adaptability. Her ability to thrive in various environments makes her a faithful companion for any grower, delivering generous crops of buds and pearly trichomes that are a testament to her vigour and strength.

Break-Up Cake Auto’s step-by-step grow guide

On this occasion, Break-Up Cake Auto will be grown in an indoor grow tent. Fluorescent lighting will be used for germination, and then the seedling will be placed under a 300W LED lamp. The nutrient plan consists of a substrate made up of an original but (why not say it) complex mixture of different elements.

The training method used will be SCROG, although this is not often applied to autoflowerings. On this occasion, though, both the vegetative and flowering phases will be longer than normal due to several issues, which will actually allow for this training technique to be applied as though she were a photo-dependent strain.

Let’s just say at this point that there’s no shortage of challenges for the grower this time! But there’s nothing better than learning from your own mistakes, especially if they can be remedied without compromising the quality of the crop, as we will see below.

Week 0

As if it were a premonition of things to come, the grower already had difficulties getting the seeds into Canada. However, he finally received them, and was impressed with Kannabia’s customer service… So rest assured he expects good results! After the successful germination of the seed in damp cotton disks, he places it in the final 5-litre fabric pot. His intention is to use a substrate mix made up of Gaia Green’s living soil, canola meal from The Ripe Tomato Farms, unscented Epsom salts, and food-grade diatomaceous earth, as well as glacial rock dust and oyster shell powder. These nutrients are mixed in specific proportions according to the growing conditions.

Vegetative phase

Weeks 1 & 2

During the first week, the seedling seems to stretch slightly due to a decrease in light intensity whilst the grower finishes the growth cycle of some cuttings in the same grow tent. In the middle of the week, after the cuttings have been taken out, the grower adds more substrate to prop the seedling and increases the light intensity to 300 PAR, which is beneficial for its development. In the second week, the grower reports that the seedling is growing well, up to 10 cm in height, although he mentions that it seems to have stopped growing towards the end of the week. He thinks it might be too early to identify a specific problem and decides to keep a careful eye to see how the situation evolves.

Weeks 3 & 4

In the third week, the grower discovers that the plant has stopped growing altogether. He realises that the living soil has become too compacted after the initial watering session, so that could be the underlying reason. He decides to keep the plant, even if she’s a bit delayed in growth, and looks after her as if she was a little child. He plans a second attempt (for another occasion), improving the substrate with coco coir to prevent it from becoming too compacted and to see if that solves the stunted growth problems. Having said that, things start working again in week 4, and the plant’s colour is spot on. He starts SCROG, topping the plant and guiding the secondary shoots into the trellis as the plant keeps growing. He spots early signs of the flowering, with calyxes pushing the pistils outwards, and decides that this will be the last vegetative week.

Preflowering phase

Weeks 5 & 6

In week five, the plant has transitioned well to the flowering stage, without showing any problems. Carbohydrates are added to the water mix to help with the absorption of nutrients. The colour of the leaves is acceptable, although slightly dark. For now, the grower focuses on watching and waiting to see how she evolves. In week six, the plant grows remarkably well, but with a slight burn on the tips of the leaves, which indicates that the nutrient mix needs to be reduced. This observation also suggests that the slow vegetative period could have been caused by the substrate mix, so he plans to soften and adjust the nutrient solution in future grows for better results.

Weeks 7 & 8

In week seven, the plant seems to be developing well. The grower prunes the lower leaves thoroughly (Lollypopping) and then adds algae and liquid nutrients to speed up her recovery from the possible stress. Some branches are also rearranged for a better distribution of the canopy on the SCROG trellis. This will be his last important intervention until the last two weeks of flowering. “I’m especially enjoying this stage”, he states. In week eight, you can tell that the plant has recovered well from the Lollypopping, with the growth of new leaves and flowering shoots. The apical stems are filling with whitish pistils at an impressive rate. She’s now at a stage of just watering and waiting, with few interventions required.

Grow parameters:

  • Daily temperature: 26ºC
  • Height: 46 cm
  • Night temperature: 20ºC
  • Hours of light: 18
  • Air humidity: 60%
  • Total dissolved solids: 200 ppm / 0.4 EC
  • Irrigation volume: 1 L per plant
  • pH: 6.4
  • Distance between lamp and plant: 71 cm

Full flowering phase

Weeks 9 & 10

In week nine, the grower states that, compared to his previous automatic grows, Break-Up Cake Auto has grown incredibly, especially after entering the flowering phase. He also highlights the pleasant aromas that she’s starting to emit. In week ten, growth is still significant, and buds are accumulating at an impressive rate. There’s still no sign of the oxidation of the first stigmas, so it seems that she will continue in full flowering mode for a few more weeks, fattening the 12+ colas that he has managed to grow thanks to the SCROG technique.

Weeks 11 & 12

In week 11, the structure of the buds looks impressive, and an increasingly intense aroma fills the grow tent. The grower shares his enthusiasm in anticipation of the harvest, comparing the waiting with the excitement of a child at Christmas: “I want to open my presents now! But I will wait as a good kid should, because I know that the reward will be much better in the end”. In week 12, the explosive fattening of the buds continues. Despite the initial compacting issue, he’s satisfied with the substrate mix, highlighting the absence of discoloration on the leaves in this advanced stage of flowering. “My congratulations to Kannabia for the excellent research and development work of this strain”, he adds.

Weeks 13 & 14

In week 13, the grower faces a major setback, as he needs to leave the plant without water for five days due to a trip to a cannabis conference, leaving his eldest son in charge of irrigation. “I can say that you already know the rest of this tragic story”. On his return, he finds the plant in poor condition and applies nutrients and algae in the hope that she can recover. Although Break-Up Cake Auto suffered less damage than might be expected, the grower feels disappointed, but hopes to be able to recover the plant “so she can reach the finish line, even if she’s limping”. In week 14, the plant seems to have recovered well after the incident of the previous week. He plans to defoliate the larger leaves to improve light penetration and help the plant finish her cycle. Although he anticipates that this could delay the finish time, he believes it is the best decision to maximise the final yield.

Weeks 15 & 16

In week 15, the grower describes his Break-up Cake Auto as “the plant that never ends”. He’s impressed with her continued growth and sounds playful and positive about the process. He takes the opportunity to remove the SCROG trellis because he believes that the huge buds can be sustained by the thick stems without any additional support. Right now, the plant is 45 cm tall, and he refers to her with a light and humorous tone, indicating that he will continue growing her indefinitely. In week 16, you can see the results of the defoliation as there are clear benefits in the development of the plant. Although this extra stress has added some time to the flowering cycle, he’s excited by the aromas that she releases.

Ripening phase

Weeks 17 & 18

In week 17, the grower reflects on the prolonged flowering of Break-Up Cake Auto. He attributes the delay to some cultivation errors, and especially to the stress caused by his son; but also to the various defoliations carried out, perhaps too many for an auto: “After all, I’m only human; and, let’s face it, bad things can happen”. However, he seems satisfied with the plant’s development and aroma. Having said that, the plant begins to show some foxtails in week 18. Foxtailing is caused by environmental or stress problems, and it manifests in the form of white pistils that grow from the buds continuously and illogically. The calyxes pile up on top of each other, creating a look that resembles the tail of a fox. This doesn’t have to be something negative in terms of cannabinoid concentration; it’s just that the buds become less compact and grow more vertical and airy. The grower decides that this will be the last week of the plant’s life cycle.

Week 19

In week 19, the grower still hasn’t harvested the plant because of other commitments, so the foxtails keep growing, which he attributes to having pushed her too hard. However, the plant’s appearance is stunning… She’s virtually a huge bunch of buds in the shape of a wedding bouquet… So big that the sugar leaves are hidden from sight. He is really excited about the harvest, as cutting time has finally arrived.



After the manicuring of the wet flowers, Break-Up Cake Auto weighs no less than 674 grams per plant, which translates into 177 grams of dry buds. Using the 300W LED light, the ratio is 0.6 grams / watt. This is one of the highest yields we’ve ever seen for an autoflowering, given all the problems that she’s had to endure.

True, she’s developed foxtailing buds, so their appearance is not the best; but this doesn’t remove any of the value of the characteristics, both in terms of terpenes and cannabinoids, which have made this Kannabia strain famous. Rest assured this is an outstanding product to make concentrates and extracts of all kinds.

As you can see, Break-Up Cake Auto is a brilliant example of endurance and strength. This is a strain that stands out for her amazing ability to overcome adversities, easily adapting to challenges like irrigation fluctuations and nutrient variations, all while maintaining a vigorous and constant growth that is reflected in her abundant and resinous buds. All of this means that she’s the perfect choice for rookie growers, as she provides a rewarding growing experience with less hassle.

So that’s Break-Up Cake Auto, a strain that symbolises power and resilience in cannabis cultivation. Her ability to adapt and flourish, no matter the challenge, is a testament to her exceptional genetics and to the commitment of Kannabia Seed Company to quality and reliability.
