Blue Mac: Potent Blueberry Bud

Offspring of the uber-popular Zkittlez and MAC strains. MAC stands for Miracle Alien Cookies. Blue Mac features an ultra-high potency, THC content, and one-of-a-kind flavour that cannabis fans absolutely love. Although Blue Mac hasn't won any major awards, its parent strains have taken home several top prizes in the cannabis world. With a massive THC content of around 28%, Blue Mac is potent enough to knock even the most seasoned cannabis users off their feet. Novice users can achieve their desired buzz by taking a few small hits of this fruity strain. Said to be one of the heavier hitters in commercial cannabis, the euphoric cerebral vibes and physical calmness are a nice touch for end-of-the-day smoke sessions.

Growing Tips for Blue Mac Seeds

Blue Mac plants grow to a medium height and reach a maximum indoor size of around 4 feet and an outdoor height of 6 feet. Like most cannabis strains, it performs best in a closely-controlled environment with plenty of warmth and sunlight, real or artificial, but because it can endure minor dips and spikes concerning heat and moisture, it serves as a solid choice for intermediate growers. Below, we've provided effective ways to simplify and streamline the growing process. Establish consistent conditions Daytime temperatures of approximately 21–27 degrees Celsius are ideal for Blue Mac plants. It is recommended that you drop the temperature during the flowering stage to encourage resin production. You can drop the temperatures between 3–8 degrees Celsius at night to mimic natural daytime and nighttime temperature swings indoors. Humidity levels should be around 40–50% during the vegetative stage, and around 30–40% during the flowering phase. A reduction in moisture can help to eliminate the risk of mould while encouraging a more potent terpene profile. Recommended Training Techniques Low-stress Training, Topping, and Screen of Green (ScrOG) are the best techniques for this particular strain. These techniques will allow the plant to grow naturally without much outside influence. Topping is crucial with this specific strain to shape the plant's size as well as trim the highest buds to allow sunlight and airflow to reach the lower levels. The ScrOG technique requires adding screens or nets to reinforce the heaviest buds so they don't break the branches during growth. Because this strain has particularly big buds, it is imperative that you utilise some techniques to reinforce the branches to keep them upright and to maintain a healthy grow. Fine-tune nutrient levels All cannabis plants benefit from nitrogen, phosphorus, and potassium (NPK). During vegetative growth, Blue Mac prefers a well-balanced nutrient cycle throughout the growth, as it promotes leaf and stem production. However, because nitrogen encourages leaf growth, it's important to reduce levels during the flowering stage. This will allow your plants to channel their efforts towards resin-rich bud development instead. To lower nitrogen levels, try using a bloom formula or simply dilute your existing feed.

Yields, Flowering Times, and Harvest

The Blue Mac cannabis strain has a flowering period of approximately 60–70 days, with outdoor harvests typically occurring in the beginning to the middle of October. Indoor growers will produce up to 550 grams of trichome-rich buds under proper care, while outdoor growers may see yields of up to 600 grams per plant, so long as environmental conditions remain stable.

Dominant Terpenes in Blue Mac

Blue Mac's pungent fruity scent and berry, citrus, sugary flavour are, in part, due to dominant terpenes caryophyllene, myrcene, and limonene. Caryophyllene is one of the most common terpenes found in nature and cannabis plants. It provides a spicy, peppery, and woody aroma profile. Myrcene is the most abundant terpene found in nature, providing this strain with earthy, musky, and fruity undertones. Limonene is most abundantly found in the rinds of citrus fruits like lemons and oranges. When found in cannabis plants, it can produce a citrusy scent and taste.

Dominant Cannabinoids in Blue Mac

Blue Mac's ultra-high THC content of around 28%, combined with its euphoric effects and massively delicious flavours have made it a popular choice among cannabis enthusiasts across Canada and beyond. Heavily relaxing physically while still allowing users to focus during its euphoric head-high, it is well-regarded as one of the strongest and fastest-acting options in modern commercial cannabis. It is recommended for nighttime use and should be taken lightly if you aren't an everyday toker. Seasoned users will thoroughly enjoy the strength, scent, and fruity flavours of Blue Mac, while experienced growers will love its relative ease of cultivation.
