Wedding Cake Auto appealed to me as a fast, indica-dominant autoflower with up to 19% THC and a flavor profile built around candy, citrus, fruit, and pine. With Wedding Cake and BF Super Auto 1 in her genetic background, I wanted to see how she would perform in my indoor setup.

This Wedding Cake Auto grow report follows one plant from germination to harvest. She developed into a tall, sturdy specimen with dense foliage, a strong central structure, and resinous flowers that took longer to mature than I initially expected.

Rather than judging the plant by the breeder’s estimated timeline, I followed her actual development week by week and waited until the flowers were properly finished. By harvest, she had reached 95 cm and produced 75 g of dried flowers.

Wedding Cake Auto Grow Report: Equipment List

• Grow tent: Secret Jardin DS120W, 120 x 60 x 178 cm
• Lighting: MIGRO Aray 4
• Ventilation: Rhino Ultra Non-Silenced 125
• Filter: Rhino Pro 125
• Growing medium: BioBizz Light-Mix
• Pot: 11 L fabric pot

• pH regulator: Plagron Lemon Kick

I planted Wedding Cake Auto directly into BioBizz Light-Mix in her final 11 L fabric pot. I used BioTabs organic nutrients throughout the grow, which allowed me to keep the feeding routine relatively simple.

The MIGRO Aray 4 provided the lighting. I started at 40% power and later increased the intensity to 60% as flowering progressed.

Daytime temperatures generally stayed close to 26 °C, while nighttime temperatures were around 25 °C. The substrate remained close to 23 °C, and I used water at approximately 22 °C.

I adjusted the irrigation water to pH 6.0 and kept the light approximately 35 cm above the canopy.

Wedding Cake Auto Week-by-Week Grow Guide

Week 1: A Compact and Healthy Start

Like the grow diaries it draws on, this grow journal tracks her height, feeding, and light settings for every week of the cycle.

Wedding Cake Auto started her first week of vegetative growth at approximately 5 cm tall.

She settled into the substrate quickly and developed a healthy green color from the beginning. Her internodal spacing was tight, giving her a compact and sturdy appearance.

By the end of the week, she had reached 8 cm.

The light remained approximately 35 cm above the canopy at 40% power. During this early stage, I used a 24/0 light schedule.

Water demand was still fairly low. I watered according to the moisture level of the substrate rather than following a fixed volume every day. One recorded watering during the week was approximately 1.5 L of water adjusted to pH 6.0.

There were no signs of stress, nutrient problems, or excessive stretching. Wedding Cake Auto looked well established and ready to begin more vigorous vegetative growth.

Week 2: Dense Vegetative Development

During week 2, Wedding Cake Auto grew from 8 cm to 17 cm.

She continued developing with very short internodal spacing. The center of the plant became increasingly dense as new leaves and branches formed close together.

The foliage remained healthy and green, and the plant showed no visible signs of nutrient deficiency or environmental stress.

I kept the MIGRO Aray 4 at 40% power and approximately 35 cm above the canopy.

Watering took place roughly every three days. I used pH-adjusted water and monitored the weight of the pot and the moisture level of the growing medium before each irrigation.

By day 14, Wedding Cake Auto measured 17 cm. She was still compact, but her growth rate was clearly beginning to increase.

Week 3: Preparing to Flower

Wedding Cake Auto increased from 17 cm to 32 cm during week 3.

Her structure remained bushy and compact, but she was now beginning to stretch more noticeably. The first signs of the transition into flowering also started to appear.

I changed the light schedule from 24/0 to 18/6 during this stage. The MIGRO Aray 4 remained at 40% power, with the fixture positioned approximately 35 cm above the canopy.

Watering continued roughly every three days using water adjusted to pH 6.0.

By the end of week 3, Wedding Cake Auto stood 32 cm tall. She had built a dense canopy and was clearly moving out of the vegetative stage.

Week 4: The First Week of Flowering

I counted week 4 as the first full week of flowering.

Wedding Cake Auto stretched rapidly during this period, growing from 32 cm to 55 cm.

The main stem became more prominent, and early flower sites started forming along the branches. Despite the increase in height, the plant maintained a compact and sturdy structure.

I carried out some light defoliation to improve airflow around the lower parts of the plant and reduce shading.

I also increased the MIGRO Aray 4 to 60% power while keeping the 18/6 light schedule.

Watering continued approximately every three days. I used pH 6.0 water and monitored the moisture level of the substrate before each irrigation.

By day 28, Wedding Cake Auto had reached 55 cm and was clearly established in the flowering stage.

Week 5: Strong Stretch and Early Bud Development

Wedding Cake Auto continued stretching during her second week of flowering and reached 80 cm by the end of the week.

This was a significant increase from the 55 cm recorded at the end of week 4.

The first buds were now becoming much more visible. Flower sites were forming along the side branches and around the main cola, although the overall development was still relatively early.

Her main stem continued to thicken, and the plant remained structurally strong despite the rapid increase in height.

The MIGRO Aray 4 remained at 60% power under an 18/6 light schedule.

I continued watering approximately every three days using water adjusted to pH 6.0.

By day 35, Wedding Cake Auto had reached 80 cm and was beginning to take on the tall, upright shape she would keep for the rest of the grow.

Week 6: Reaching 94 cm

During week 6, Wedding Cake Auto gained another 14 cm and reached 94 cm.

The vertical stretch was beginning to slow, but the plant had grown considerably taller than the typical indoor height listed for the strain.

Flowering continued, although bud development was more gradual than the rapid stretch had been. The plant remained completely healthy, so I did not make any major changes.

The BioTabs organic nutrient system kept the routine straightforward. I continued supplying mostly pH-adjusted water and allowed the prepared growing medium to provide the nutrients the plant needed.

The lamp remained approximately 35 cm above the canopy at 60% power.

By the end of the week, Wedding Cake Auto stood 94 cm tall and was focusing more of her energy on flower production.

Week 7: Final Height and Increasing Flower Production

Wedding Cake Auto reached her final height of 95 cm during week 7.

At this point, vertical growth had effectively stopped.

Flower development became much more noticeable. Fresh white pistils appeared in greater numbers, and the flowers along the main cola and side branches began to fill out.

The plant maintained a dense canopy. I only removed leaves when they were clearly blocking light or limiting airflow around important flower sites.

The MIGRO Aray 4 remained at 60% power with an 18/6 light schedule.

Watering demand had increased as the plant became larger. I continued irrigating roughly every three days, always checking the moisture level of the growing medium before watering.

Wedding Cake Auto remained healthy and stable, and the focus had clearly shifted from vertical growth to flower production.

Week 8: The First Visible Trichomes

Wedding Cake Auto remained at 95 cm during week 8.

The flowers continued to develop, and the first clearly visible trichomes began appearing across the buds and surrounding sugar leaves.

Resin production was now becoming much more obvious, although the flowers still needed additional time to mature.

The aroma also started to become stronger during this stage.

Daytime temperatures remained close to 26 °C, and relative humidity was approximately 45%. The light stayed at 60% power and approximately 35 cm above the canopy.

Watering continued approximately every three days using pH-adjusted water.

I also noticed some older fan leaves beginning to yellow naturally. I removed them when necessary but avoided unnecessary defoliation because the plant remained healthy.

Week 9: Buds Begin to Gain Weight

During week 9, Wedding Cake Auto concentrated entirely on flower development.

The main cola became denser, and the side branches began filling out more evenly. Trichome production increased, making the flowers noticeably stickier.

By this stage, I could see that this particular plant was not going to finish as quickly as the standard product timeline might suggest.

However, the plant showed no signs of stress or declining health, so I continued to let her mature at her own pace.

The light remained on an 18/6 schedule at 60% power, and I continued watering roughly every three days using water adjusted to pH 6.0.

Week 10: Resin and Density Increase

Wedding Cake Auto continued to put on flower weight during week 10.

The buds became firmer and more compact, while the resin layer across the flowers became increasingly visible.

The plant maintained her final height of 95 cm and required very little intervention beyond routine watering and environmental control.

This stage confirmed that patience was important with this particular specimen. The flowers were progressing well, but they were not yet ready for harvest.

I continued using pH-adjusted water and kept the environment stable.

Week 11: Final Ripening

By week 11, the buds had become dense, sticky, and heavily coated in resin.

The aroma was also much stronger than it had been earlier in flowering.

At this stage, I focused on monitoring the maturity of the flowers rather than making any further changes to the plant.

The leaves showed natural signs of late flowering, while the buds continued to harden and ripen.

Wedding Cake Auto remained healthy and structurally strong throughout the final stage.

Week 12: Harvest

I harvested Wedding Cake Auto during week 12.

By this point, she had reached a final height of 95 cm and had completed a significantly longer cycle than the standard estimate given for the strain.

The extra time was worthwhile. The finished buds were dense, hard, oily, and extremely sticky, with a generous coating of resin.

The plant had remained healthy throughout the grow. I encountered no major issues with pests, disease, mold, nutrient deficiencies, or structural weakness.

After drying, Wedding Cake Auto produced 75 g of flowers.

Wedding Cake Auto Harvest Results

Wedding Cake Auto produced 75 g of dried flowers from one plant.

The final buds were dense, firm, sticky, and resinous.

I rated the overall difficulty as moderate rather than difficult. The plant itself was healthy and uncomplicated, but her slower flowering development required patience.

The official Wedding Cake Auto profile lists indoor plants at 60–70 cm. My plant reached 95 cm, showing how much individual growth can vary depending on environment and cultivation conditions.

The breeder also lists indoor yields of 400–450 g/m². My result of 75 g represents a single plant grown under one specific indoor setup and should be viewed in that context.

Wedding Cake Auto Growth Characteristics

Wedding Cake Auto started as a compact, bushy plant with very tight internodal spacing.

Her early growth was steady rather than explosive. She measured 8 cm at the end of week 1, 17 cm after week 2, and 32 cm after week 3.

Once flowering began, the stretch became much more pronounced. She grew to 55 cm during week 4, 80 cm during week 5, 94 cm during week 6, and finally stopped at 95 cm in week 7.

This made her considerably taller than the typical indoor range of 60–70 cm listed for the strain.

I did not apply heavy training to limit her height, which allowed her natural structure to develop.

The plant remained sturdy throughout the stretch. Her main stem thickened considerably, and the branches were strong enough to support the developing buds.

Flower production took longer than the early vertical growth. The buds really began gaining density and resin during the later flowering weeks.

Overall, Wedding Cake Auto proved vigorous, structurally strong, and relatively easy to manage, although this particular plant needed more time to finish than expected.

Wedding Cake Auto Genetic Attributes

Wedding Cake Auto is an autoflowering hybrid created by crossing Wedding Cake with BF Super Auto 1.

Royal Queen Seeds developed this version to retain the desirable traits of the original Wedding Cake while adding autoflowering genetics and a shorter, more manageable growing cycle.

The strain is 75% indica, 20% sativa, and 5% ruderalis, making it strongly indica-dominant.

THC levels reach up to 19%, while CBD levels remain low.

The official flowering time is 50–55 days, with harvest typically expected 70–75 days after germination.

However, this individual plant required a longer cycle. That difference is important when interpreting grow reports. Breeder figures provide a useful guideline, but individual plants can take more or less time depending on phenotype, environment, lighting, nutrition, and other growing conditions.

Wedding Cake Auto Flavor and Aroma

Wedding Cake Auto is known for flavors of candy, citrus, fruit, and pine.

The sweet side of the profile reflects the Wedding Cake lineage, while citrus and fruit introduce brighter notes. Pine adds a fresher, more botanical character.

During this grow, the aroma developed gradually.

There was little noticeable smell during the vegetative phase, and the fragrance remained relatively mild during early flowering.

As the buds became denser and resin production increased in the later stages, the aroma became much stronger.

By harvest, the flowers were oily, sticky, and highly resinous, with the aromatic profile becoming much more pronounced than it had been earlier in the cycle.

Wedding Cake Auto Effects

Wedding Cake Auto contains up to 19% THC and is described as producing euphoric, uplifting, and physically relaxing effects.

The indica-dominant genetic profile gives the overall experience a relaxing physical character, while the euphoric and uplifting qualities help to keep the effect balanced.

This combination makes Wedding Cake Auto well suited to moments when I want to unwind while still enjoying an upbeat mental effect.

The physical relaxation becomes more noticeable as the experience develops.

As with any cannabis strain, individual effects can vary according to tolerance, quantity consumed, setting, and method of consumption.

Final Thoughts on My Wedding Cake Auto Grow Diary

Wedding Cake Auto turned out to be a grow that rewarded patience.

She started as a compact seedling with tight internodal spacing before stretching rapidly once flowering began.

Her height increased from just 8 cm at the end of week 1 to a final 95 cm by week 7. This was considerably taller than the typical indoor range listed for the strain, but the plant remained easy to manage because her structure was strong and stable.

Flower development was slower than I initially expected. Instead of harvesting according to a fixed breeder estimate, I followed the condition of the flowers and allowed the plant to continue until they had developed the density and resin I wanted.

That decision resulted in 75 g of dried flowers from one plant.

The BioTabs organic nutrient system also kept the grow straightforward. I mainly relied on the prepared substrate and pH-adjusted water, while the MIGRO Aray 4 provided consistent light throughout the cycle.

Wedding Cake Auto remained healthy from beginning to end and required little corrective work beyond light defoliation, watering, and environmental management.

For me, the standout traits were her strong growth, sturdy structure, dense resinous flowers, and sweet, fruity flavor profile. This Wedding Cake Auto grow diary showed that even an autoflower can benefit from extra patience when the plant itself indicates that it needs more time.
