Part Two: Pre-Flowering and Flowering Stages for Cannabis


Welcome back to our series: The Complete Guide to Growing at Home.

In our first installment, we covered the initial stages of cannabis cultivation - from seedling to the vegetative stage. Now, we move into the thrilling world of pre-flowering and flowering - the most pivotal phases in the life of your cannabis plants. If you're a home grower in Minnesota, this guide is tailored just for you.

Understanding the Pre-flowering Stage

The pre-flowering stage is a short transition period between the vegetative and flowering stages.

This stage is crucial as it is the first sign of your plant's sex. Male plants develop pollen sacs, while female plants form pistils. Identifying and separating male plants is essential for those interested in producing smokable buds to prevent pollination.

The Flowering Stage

As daylight hours decrease, cannabis plants naturally transition into the flowering stage, focusing their energy on producing buds.

Depending on the strain, this stage can last anywhere from 7 to 11 weeks. Each plant's unique characteristics really begin to show, and the aroma of your cannabis begins to fill the air.

Feminized, Regular, Auto Flower, and Fast Flower Strains

When cultivating cannabis, understanding the different strains and their characteristics is critical. Here's a brief overview:

Feminized Strains: Feminized cannabis seeds are bred to eliminate male chromosomes, virtually ensuring that every plant grown from the seed will flower as a female. For growers aiming for high-quality buds, feminized strains are an excellent choice.

Regular Strains: Regular cannabis seeds are a mix of male and female seeds. These are perfect for growers interested in breeding new strains or growing cannabis in its most natural form.

Auto Flower Strains: Auto-flowering strains automatically transition from the vegetative stage to the flowering stage with age, rather than changing light conditions. These strains are great for beginners and those looking for a fast harvest.

Fast Flower Strains: Fast flowering strains are bred to flower in less time than traditional strains. This characteristic allows for multiple harvests within a single growing season.

Nurturing Your Cannabis Through the Flowering Stage

Caring for cannabis during the flowering stage requires a precise balance of light, nutrients, and water.

Your plants will require more phosphorus and potassium to support bud growth during this time. However, overfeeding can lead to nutrient burn, so careful monitoring is key. Furthermore, during this phase, you need to inspect your plants daily for pests and diseases.

Lighting Considerations

Regarding the flowering stage, lighting is one of the most crucial factors influencing your cannabis plant's growth and yield. Whether you're growing your plants indoors or outdoors, understanding their lighting needs is vital.

Indoor Lighting

Indoor growers can control their growing environment, including light exposure. During the flowering stage, cannabis plants require a balanced 12/12 light cycle - 12 hours of light and 12 hours of uninterrupted darkness each day. This schedule mimics the natural conditions of autumn and encourages the plant to flower.

A variety of lighting solutions are available for indoor growers, including High-Intensity Discharge (HID) lamps, Compact Fluorescent Lights (CFLs), and Light Emitting Diodes (LEDs). Each has pros and cons, and the choice largely depends on your budget, growing space size, and energy consumption preferences.

Outdoor Lighting

Outdoor growers in Minnesota have to work with the sun and seasons. While indoor growers can trigger the flowering stage at their convenience, outdoor growers must wait for Mother Nature.

In Minnesota, the flowering stage for outdoor cannabis plants typically starts around late July or early August, when the days begin to get shorter. The plants will usually continue flowering until late September to mid-October, depending on the strain and the weather conditions. However, it's important to keep an eye on your plants and the local weather forecasts - an early frost can be detrimental to your crop.

It's worth noting that during the flowering stage, cannabis plants still need a period of darkness each day. If you're growing in an area with streetlights or other sources of nighttime light pollution, consider solutions like light-deprivation tarps to ensure your plants get the darkness they need.

In conclusion, understanding and meeting your cannabis plant's light needs during the flowering stage is crucial to successful cultivation. By carefully managing your plant's light exposure, you can influence your buds' size, density, and potency.

The Journey Continues: The Final Stages of Flowering

As we approach the end of the flowering stage, the real magic begins to happen. During this final phase, your plants put all their energy into creating the most potent and dense buds possible.

Bud Ripening and Pistil Changes

As the flowering stage progresses, your cannabis buds will undergo a transformation known as ripening. The pistils - those hair-like structures on your buds - will change from a light, whitish color to a darker orange or brown. This color change is a clear sign that your buds are maturing.

During this time, your cannabis plant is also producing cannabinoids and terpenes, the compounds responsible for the effects and aroma of your cannabis.

The Final Bulking Process

The flowering stage's final weeks are often called the 'bulking phase.' This is when your cannabis buds will put on the most weight. Your plants are working hard to produce large, resin-covered buds. It's essential to keep giving your plants the necessary nutrients to support this rapid growth.

Remember, however, that each strain is unique. The length and exact timing of these final stages can vary based on the specific strain you're growing and the growing conditions. As always, careful observation of your plants is the best guide.

This final flowering phase is critical to your cannabis plant's life cycle. It's a time of significant changes and rapid growth, and the care you provide during this time can greatly impact the quality and potency of your final product.
