Alien OG: Out of This World
Alien OG seeds grow into short and stocky plants covered with dark green leaves and hefty buds. The leaves are small, and the majority of them rest below the cone-shaped bud sites. The entire plant is dark green, but because of a layer of frosty white resin, the plants actually look pale green. Each bud features red and orange pistils that are hard to see through the trichomes. The harvested nuggets are bright green and orange and leafy, which makes them easy to break up with your fingers. Doing so will release a fuel-like aroma and coat your hands in dusty resin. Although the uber-popular Alien OG strain has yet to win any major cannabis awards, it has earned recognition at smaller, local events and competitions. With a wealth of solid reviews online, Alien OG is constantly growing in popularity among cultivators and cannabis enthusiasts across Canada. If you're thinking of growing this strain for yourself, we have some helpful tips that will assist in getting your plants to harvest.
Growing Tips for Our Seeds
The Alien OG strain can be grown by cultivators of all levels as long as you have an intermediate amount of cannabis cultivation experience. This strain does best in a warm, sunny environment with loads of fresh air. Consistent temperature and humidity will allow this strain to thrive indoors or outdoors. Because the strain is already resistant to moulds, pests, and diseases, it is considered by most to be low maintenance. Alien OG plants have been known to have issues with their root system, so giving them plenty of space and quality nutrients will help them grow big and strong. Expert growers recommend potting with rock wool to help Alien OG reach its best harvests.
Dial in Your Growing Conditions
- Indoor or Outdoor: Alien OG can be grown indoors and outdoors by experienced growers. The desired temperature for this strain is between 18–24 degrees Celsius. This strain requires 18–20 hours of light during the vegetative stage. Switching to a 12/12 light cycle will induce the flowering stage and get you all the way to harvest.
- Moisture Control: Humidity levels of approximately 50% during the vegetative phase, gradually decreasing to 40–50% or slightly lower during the flowering stage.
- Training Techniques: Alien OG plants tend to grow bushy rather than tall. Top them so that light and air can circulate to their lower growing nodes. Topping will also help increase your yields when you are ready to harvest these plants. Low-stress training (LST) is also a solid method to use on this specific strain.
Yields, Flowering Time, and Harvest
- Flowering Time: Growing indoors, you can expect the Alien OG strain to be harvest-ready after a short flowering period of 55–65 days. Outdoors, it should be harvest-ready sometime in October, depending on when you planted your seeds.
- Yields: Indoor yields are around 310 grams per square metre, while outdoor grows typically produce up to 375 grams per plant. Because Alien OG grows compact, you can make the most of your allowable plants and maximise your overall harvest. Regardless, these yield numbers are a satisfying result to a somewhat challenging grow.
Dominant Terpenes in Alien OG: Diesel Scent
The Alien OG terpene profile is directly responsible for how the plant smells and tastes and the strong effects it has on its users. The most dominant terpene in this strain is myrcene, while limonene and linalool are secondary terpenes.
- Myrcene: Most Dominant – Earthy and herbal, contributing to the strain's relaxing effects on the user. Also known as the "Mother of Terpenes".
- Limonene: Secondary Terpene – Found in the rinds of citrus fruits, this terpene, also found in cannabis plants, can help improve lung function.
- Linalool: Spicy Terpene – Found in basil, lavender, and cannabis, this terpene plays a big role in the effects cannabis has on the user.
Dominant Cannabinoids in Alien OG:
Cannabinoids play an important role in Alien OG seeds and are generally a huge part of most strains of cannabis. That focused, euphoric, and happy feeling you get when enjoying the Alien OG strain is due to its dominant cannabinoids. Each cannabinoid does something different to the user.
- THC: The Main Character - THC is the most dominant cannabinoid on the molecular level of this strain. The crystalline compound tetrahydrocannabinol is the main ingredient of cannabis. Topping out at a massive 28%, the THC in this evenly balanced hybrid strain is responsible for the happy and euphoric feeling you get when enjoying Alien OG cannabis.
- CBD: Very Minimal Amounts - While the CBD levels in Alien OG are less than 1%, the cannabinoid is still present, and the effects are noticeable in this strain. CBD plays a smaller role in what the strain does to the user. CBD is non-psychoactive and can produce effects that help with anxiety, sleep, pain, and even stress. The CBD in the Alien OG strain, even in its lower amounts, definitely has a positive effect on the user.
