Northern Lights autoflower, the original abbreviated, "NL," is an Indica cannabis strain created by combining Afghani and Thai. Northern Lights origins are frequently questioned, with some saying that the variety was initially grown in Seattle. However, it is widely believed that Sensi Seeds invented Northern Lights Autoflower seeds in the late 1980s in the Netherlands. It didn't take long after Northern Lights Auto seeds were introduced to the scene for them to begin winning multiple prizes all around the world.

The time it takes for Northern Lights Auto seeds to germinate with the paper towel approach varies according to the environmental conditions. Northern Lights Autoflower seeds can sprout in less than seven days if germinated in ideal circumstances, but they can take up to 10 days if not germinated in optimal conditions. Premium Cultivars recommends that all Northern Lights Auto producers use the paper towel approach, which has shown to be quite effective. The following are simple methods for germinating your Northern Lights Autoflowering seeds using the paper towel method:
Autoflowering strains are becoming increasingly popular in the cannabis world. These seeds require half the time that ordinary seeds need to mature into bud-producing plants. Because of their quick growing cycle, Autoflower seeds are ideal for novices. All automatic plants can begin the blooming period regardless of the light cycle. Conversely, regular seeds are non-genetically altered cannabis seeds. These seeds are often created by natural seed reproduction, which involves breeding a male and female plant. It is the most basic and crude cannabis planting technique. Furthermore, these seeds are neither artificially reproduced nor subjected to genetic modifications.
Autoflowering strains are cannabis seeds that blossom independently and do not require a specific light cycle. They only begin to blossom after the plant reaches a particular stage of maturity, which takes around two months. In contrast to photoperiod-dependent strains, Autoflower seed spontaneously transitions from vegetative to flowering growth as they mature. In comparison, photoperiod-dependent strains require a specific ratio of light to dark hours. It implies that you must keep your plant in sunlight for 12 hours and darkness for 12 hours. As a result, indoor producers must adhere to a precise timetable.
However, the introduction of Feminized seeds in the 1990s altered how the cannabis growing business was perceived. The genetic modification of this kind of seed is designed to remove all male chromosomes altogether, leaving just the female ones to be used. This modification makes it possible to prevent the seeds from developing into males. As might be predicted, the cost of these seeds is far more than that of regular seeds. They are typically preferred to avoid unintentional pollination or hermaphroditism in the group.
Northern Lights is a reasonably simple strain to grow, with good tolerance to illnesses, pests, bugs, powdery mildew, and mold. These qualities combine to make this Autoflowering strain one of the best choices for inexperienced growers. The plant's dark green buds will get coated in a dense and dazzling layer of trichomes as they grow.
It is straightforward to grow Northern Lights Auto seeds in indoor or outdoor environments and only grow to a modest height.
Northern Lights Autoflower seeds thrive indoors, particularly in a SOG environment. Also, you do not need to be concerned about the size of your growing area. These cannabis plants will take up little space indoors.
Harvest occurs around the middle of October when grown outdoors.
Outdoors, you may expect a harvest of around 22 ounces per plant. Indoor yields are somewhat lower, at 18 ounces per square meter.
Autoflower seeds provide low to medium yields compared to conventional and Feminized seeds. Conversely, these Autoflowering seeds bloom and produce more quickly.
Northern Lights Auto seeds, like other cannabis plants, require a lot of nitrogen (N) during the vegetative stage. The blossoming phase also requires a lot of phosphorus (P) and potassium (K). However, these Auto seeds can absorb more significant levels of N throughout their growth cycle than other cannabis strains because it is less likely to have nitrogen burn.
Northern Lights thrive in both hydroponics and soil. Whether you're utilizing soil or hydroponics, the pH of your growing medium will significantly impact your harvests.
A warm, humid Mediterranean environment, comparable to that of California or Northern Africa, is suitable for growing Northern lights outside. However, indoor conditions must be climate controlled.
In an indoor environment, Northern Lights Auto seeds develop into a small to medium-sized plant that requires 10 to 12 weeks to complete its life cycle and receives 18 hours of light daily.
Your Northern Lights Auto seeds take 10-12 weeks to grow fully. You are urged to use various plant training techniques to assist the Northern Lights Autoflowering seeds in developing fast and getting adequate yields.
If you are a rookie grower, be cautious of overfeeding since it can happen faster than you believe. Another issue with growing indoors is the high cost of lights.
Northern Lights Autoflowering seeds are easy-to-cultivate cannabis.
Northern Lights Auto seeds are suitable for beginners and are much easier to nurture. Furthermore, these tough Autoflower seeds resist most outdoor pests, molds, and illnesses.
Defoliation is the method of removing leaves from your plants. It should only be used in particular settings and is ineffective for increasing outdoor yields. The incorrect defoliation method concentrates on removing slow-growing and 'sickly' leaves. The issue is that the technique makes weak plants worse and more prone to disease. Although it is effective when done correctly, defoliation might harm your plants if done incorrectly.
SOG is a method that includes growing many little plants in a small area. Your harvest will resemble a sea of green plants, as the name implies. You drive your cannabis plants into the blooming period early with the sea of green growth strategy. This is because cola growth needs just half of the plants to attain maximum size. Aside from a shorter vegetative phase, the blooming cycle is also shortened. The Sea of Green (SOG) entails producing many small cannabis plants rather than a few bigger ones. SOG benefits include a shorter vegetative phase, less area required, and increased lighting efficiency. Indoor cannabis farmers know that their energy expenses are greater than the norm. Additionally, SOG will not lower your costs, but it may increase the amount of cannabis you cultivate.
LST includes gradually bending the branches down to sit flat rather than expanding upwards. Auto seeds are modified by growers using Low Stress Training to change their size and form. To boost productivity and yields, cannabis plants are twisted and tied to their branches. LST's flat canopy and short, wide plant structure enable buds to utilize the available light and space.
Comparable cannabis seeds to Northern Lights Auto are Critical Mass, Afghani Skunk, Pink Kush, and Purple Passion.
