Week 12: Final Stretch to Harvest Glory

The Black Muffin plants are putting on a stunning show as some phenotypes are turning deep, rich shades of purple. These vibrant colors, combined with their frosty trichome coverage, make the buds look like they've been dusted in sugar. The dense, chunky flowers are truly a sight to behold, with well-formed colas that hint at an impressive harvest. Fan leaves are fading naturally, adding to the overall visual appeal of a garden in its final stage.

Grow Characteristics

This week saw a slight nutrient deficiency show up, but the plants seem to have bounced back well with minor adjustments. The nutrient issue hasn’t hindered the plants’ overall health, and their structure remains strong and resilient. The buds are swelling beautifully, and the resin production is at its peak. Proper airflow and humidity control have been key in maintaining their health as they approach harvest.

Expectations

With harvest just a week away, all signs point to a high-quality yield. The deep purple phenotypes promise a flavorful and aromatic product, while the overall resin production hints at strong potency. The trichomes are mostly milky with a few amber appearing, signaling the perfect time to start preparing for the chop. This Black Muffin grow has been a rewarding journey, and we’re excited to see these gorgeous plants transform into top-shelf cured buds.

Week 10: Black Muffin’s Journey to Full Bloom

At Week 10, Black Muffin is showing incredible potential as it nears its peak over the next few weeks. The strain is already making a strong impression with its vibrant colors, rich aroma, and promising bud structure. Here’s what we’re seeing as Black Muffin progresses toward full maturity.

Appearance

Black Muffin’s buds are developing beautiful, deep purple hues that contrast stunningly with the lush green leaves. Each bud is dense and packed with resin, giving them a frosty, eye-catching look. As the plants continue to mature, these colors will deepen, adding even more visual appeal in the coming weeks.

Grow Characteristics

The aroma is intensifying as the plants approach their peak. Black Muffin fills the grow space with a complex scent of earthy sweetness and creamy vanilla undertones. The terpene profile is rich and balanced, hinting at the unique flavors that will be even more pronounced as harvest nears. This strain’s bold, layered aroma is a pleasure for the senses.

Expectations

With about 3-4 weeks left to reach its peak, Black Muffin is on track for a productive harvest. The lush purple buds and enticing aroma promise a memorable yield. And with a 25% discount available until harvest, now’s the perfect time to add this unique strain to your grow collection!

Week 7-8: Strong Growth, Vibrant Colors, and Rich Aroma

At Week 8, Black Muffin is showing impressive development across the board. With strong structure, vibrant foliage, and a unique aroma already emerging, this strain is on track for a high-quality harvest.

Appearance

Black Muffin’s plants are in peak health, with dense, rich green foliage and evenly spaced nodes that allow for excellent light penetration. The thick fan leaves and balanced structure support vigorous growth, while subtle purple hues are starting to appear, adding visual interest to the buds.

Grow Characteristics

The buds are forming thick, tight clusters, already showing substantial resin coverage. The aroma is intensifying, filling the space with a blend of sweet and earthy notes that hint at a complex terpene profile. This development suggests Black Muffin will bring both potency and character to the final harvest.

Expectations

With around 5-6 weeks left until full maturity, maintaining stable humidity and airflow is key to supporting bud health. Black Muffin is shaping up to be a high-yield, aromatic strain, with every indication pointing toward a rewarding and fragrant harvest.

Week 4-5: Topping, training and prepping for blooming

We’re entering week 4-5 of the Black Muffin grow, and things are looking green and healthy across the board! These weeks have been focused on training and prepping for the upcoming flower stage, keeping the canopy even and ensuring the plants don't outgrow their space.

Appearance

The Black Muffin plants are thriving, with rich, deep green leaves and sturdy stems. One plant, however, decided to take off and grow faster than the rest, so we had to top it to keep everything in check. The rest are maintaining a good, bushy structure, and the overall canopy is filling out nicely. The tent is now packed with vibrant foliage, creating a beautiful green jungle.

Grow Characteristics

As mentioned, one plant grew a bit too tall, so topping was necessary to keep everything even. We also put up a trellis net to spread the canopy and allow light to hit all the bud sites evenly. This should help to maximize yield and keep the plants from shading each other out. The branches are sturdy, and they’re responding well to the light training, bending and adjusting to fill the space without overcrowding. These girls are strong, with great node spacing and solid growth.

Expectations

We’re putting the plants into flower this week because, at this rate, they’ll outgrow the tent if we wait any longer! We’re expecting the typical stretch in the first couple of weeks of flowering, so it’s essential to stay ahead of that. The canopy looks even, the plants are strong, and with the trellis in place, we're anticipating good bud development with solid light penetration. Excited to see the buds start forming and the Black Muffin’s famous resinous, chunky flowers begin to take shape.

On to the flowering stage, let’s see these beauties bloom!

Appearance:

In just two weeks, these little ones are thriving. They’re showing off a beautiful, healthy green color and look strong with nice early leaf development. All signs are pointing to a happy, productive grow.

Grow Characteristics:

Black Muffin is making impressive strides in its early growth stages. The plants are well-structured and growing steadily, with no issues so far. They seem to love their environment and are making good progress with every passing day.

Expectations:

Given the strong start, we’re expecting these beauties to hit their stride soon and grow into some hefty, resin-covered buds. If they keep this pace, Black Muffin is set to be a real standout in our garden!
