303 OG: Dense and Dank
303 OG seeds grow into plants that exhibit distinctive physical characteristics, making them easy to recognize in a room full of plants. They typically have dense and compact buds covered in a thick layer of crystal trichomes, which gives them a frosty appearance. The leaves are deep green and broad and sometimes have a purple hue, especially during the flowering stage. The plants tend to grow medium to tall with sturdy branches that can support the weight of the resinous buds. Breaking apart the dense nuggets post-harvest will leave your fingers sticky and skunky. If you are thinking about growing this strain but want a peek at its resume first, we’ve got you covered. While this strain hasn’t taken home any major awards, it has done well locally in California and Colorado. We anticipate this strain winning multiple bigger awards in the future. It has been nominated but the big trophies have eluded it in its short life. Growers and users have submitted tons of quality reviews online so if you’re looking for first-hand testimonials, they are there.
Growing Tips for Our Seeds
303 OG seeds can be grown successfully indoors and outdoors. Indoor cultivation provides better control over environmental factors like temperature, humidity, and lighting, resulting in optimal plant growth when done correctly. It thrives in an indoor environment. Outdoor cultivation allows plants to benefit from natural sunlight and fresh air, potentially leading to larger yields. Providing well-drained soil and nutrient-rich mediums, along with regular watering and supplements, will contribute to the successful growth of 303 OG. Novice growers shouldn’t have an issue bringing this strain to harvest.
Dial in Your Growing Conditions
- Indoor or Outdoor: 303 OG cannabis plants can be grown indoors and outdoors by first-time growers. The ideal temperature for these plants is between 68-77 degrees Fahrenheit. During the vegetative stage, utilize an 18 to 20-hour light schedule. Changing to a 12/12 light cycle will induce flowering and get this plant to harvest.
- Moisture control: Humidity levels of approximately 50-70% during the vegetative phase, gradually decreasing to 40-50% or lower during the flowering stage. This change in humidity will help keep mold off of your plants.
- Training Techniques: One technique that is beneficial to auto flowering strains of cannabis is Low-stress training or LST. This method helps adjust the plant’s leaves so that ample light and air can reach the bottom of the plant. It also helps to increase yield numbers to reach their full potential.
Yields, Flowering Time, and Harvest
- Flowering Time: Growing indoors, you can expect the 303 OG strain to harvest after a flowering period of 60-70 days. Outdoor growers should be ready for harvest sometime near the end of October or the beginning of November, depending on when you planted your seeds.
- Yields: While Indoor yields are around 300 grams per square meter, outdoor grows typically produce up to 350 grams per plant. These yields are great. To increase these numbers, you can plant multiple plants because of how small 303 OG grows. This will increase your yields exponentially.
Dominant Terpenes in 303 OG: Sweet and Spicy
The 303 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 limonene, while linalool and myrcene are secondary terpenes.
- Limonene: Most Dominant – Found in the rinds of citrus fruits, this terpene can improve lung function when found in cannabis.
- Linalool: Secondary Terpene – Found in lavender and basil, this terpene helps with anxiety and acts as a sedative.
- Myrcene: Earthy Flavor – The “Mother of all Terpenes”, myrcene has an earthy and woodsy aroma and flavor to it.
Dominant Cannabinoids in 303 OG:
Cannabinoids play an important role in 303 OG seeds and are generally a huge part of most strains of cannabis. That creative, uplifting, and euphoric feeling you get when enjoying the 303 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 26%, the THC in this evenly balanced strain is responsible for the uplifted and euphoric feeling you get when enjoying 303 OG cannabis.
- CBD: Very Minimal Amounts – While the CBD levels in 303 OG are around 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 303 OG strain, even in its lower amounts, definitely has a positive effect on the user.

Had some mailing issues at first, explained the situation and customer support hooked me up no problem! Great customer service only added a great experience once i got the seeds, have yet to finish growing them but so far so good, been about 4 weeks in and the progress is promising.
303 OG is the perfect after-work strain. It’s an easy grow, too, which is why I was so excited about it. It takes about 3 months, a definite summer hobby for me 🙂 I got recommended this site by a friend. We always smoke pot together and recently she started sharing her homegrown stash and I was floored by the quality. I knew I needed to buy my own seeds and start growing at home. GREAT product. Very excited to return the favor!
