No matter how carefully you grow your marijuana plants, low-quality genetics will thwart your efforts. Traditionally, Northern Lights is a hard-hitting indica, but it can help create well-known hybrids such as Shiva Skunk and Super Silver Haze. Although you can purchase NL seeds online, it is best if you seek out local gardeners as they can sell you seeds that are acclimated and bred for the climate.
Northern Lights is typical of most marijuana plants in that it needs high levels of nitrogen (N) during the vegetative stage. It also requires high amounts of phosphorus (P) and potassium (K) during the flowering stage. Unlike most weed strains, however, NL can take higher levels of N throughout its growing cycle because it is less likely to feel nitrogen burn.
Northern Lights grows well using the Sea of Green (SOG) method, and you can use soil or a hydroponic growing medium. You can also benefit from multiple growth cycles each year if you can use indoors and outdoors to your advantage. Use outdoor light during the flowering process and indoor light for vegetative growth and germination. This process helps utilize the natural light cycle, reduce your energy bill, and enjoy several harvests per year.
Tip #1 – Finding Great Genetics
Once your plant begins to flower, it is time to reduce the humidity by 5% per week. Lower temperatures are also vital at this point because it helps your Northern Lights plant produce potent buds covered in trichomes. There are plenty of all-in-one devices on the market that enable you to monitor humidity and temperature.
These are the biggest issues facing marijuana growers today, and cultivating Northern Lights indoors does not spare you. Prevention is always the best option, which means maintaining a clean growing area and excellent personal hygiene. Although NL is one of the most pest-resistant strains on the market, you can’t afford carelessness.
You can stop pests or infections from gaining a foothold by ensuring the humidity and temperature of your grow area are at optimal levels. You must filter the air intake because it blocks a significant path for pests. A high-quality household filter should prevent most insects, hair, and dust from getting in.
Tip #3 – Put the ‘Lights’ in Northern Lights
For the uninitiated, the pH of a substance is a measure of its acidity or alkalinity. On the pH Scale, anything below 7.0 is acidic and anything above 7.0 (to 14.0) is alkaline. The decimal points on the scale are crucial because the concentration changes by a factor of ten for every whole point. Therefore, an increase from 6.0 to 7.0 is a tenfold increase! If you are even 0.2 or 0.3 outside the optimal range, the growth of your marijuana will suffer.
Here are a few pests and diseases to watch out for:
During week 4 of the vegetative growth, you will see the flowering sites starting to turn light green, this means the pre-flowering stage is coming, by now, you will clearly see the difference in size overnight when your plants are fully growing, you’ll see up to 2 pairs of leaves fully developed per day, this is a sign that your plant is thriving
On the fifth week, your plants are officially in the pre-flowering stage, even though it may take a couple of days, you will see the stigmas (white hairs) appearing on all of the flowering sites that were turning light green a couple of days ago, that is, if you are growing feminized seeds, if not, your plant may grow pollen sacs, meaning it’s a male plant.
Also, depending on the medium, you will have to provide the micronutrients your plants need, in this case, the grower had to mix calmag in the nutrient solution, this happens because coco fiber and perlite are sterile and unlike soil, they don’t contain the micronutrients a cannabis plant needs.
Week 4 – Vegetative stage
In this grow journal, our growers started by germinating a couple of Northern Lights Auto seeds in a paper towel, this isn’t the method we usually recommend, soaking the seeds allows the water to soften the shell, thus increasing the chances of germination.
By now, you should already be feeding at least half the dose of blooming nutrients and slightly increasing the dose with every watering, always paying attention to signs of deficiencies that your plant will surely show if you overfeed.
Week 5 – Pre-flowering stage
By flushing, you’re removing the excess nutrients that make your buds taste harsh and also improve the smell and flavor so if possible, use filtered water or at least leave water in a bucket under the sun for around 48hs to evaporate all of the chlorine in it to avoid stressing your plants.
Even though the seed has already germinated, it can take a couple of days for the seedling to come out of the medium but after it’s come out and you see the small rounded leaves, you have officially started your growing cycle.
