We share advice in this OG Kush grow guide to help you reach a successful harvest. But first, a quick rundown of the strains.

What Is OG Kush?

One of the most well-known and renowned cannabis strains of all time is OG Kush. Despite its fame, the origins of OG Kush are buried in mystery, with various distinct stories surrounding its development. Many people believe it’s a hybrid of Lemon Thai, Chemdawg, Hindu Kush, and an unidentified Northern Californian strain.

The fact that OG Kush is an indica-dominant hybrid is universally acknowledged. It’s a strain with a THC level of up to 27%, making it extremely strong. OG Kush gives you an extremely powerful high that strikes you quickly. After a while, the intellectual buzz can become sedating, resulting in couch-lock. The earthy, pungent aroma is enticing, and the gleaming resinous crystals are appealing to the eye.

Some medicinal marijuana users use it to treat sleeplessness due to its sedative properties. Some people take it to treat sadness and anxiety because it has mood-enhancing properties, especially in its early stages.

Because OG Kush is a rather pricey strain, growing it at home can save you money. Continue reading the best guide from USA’s best cultivators i49 to find out how to grow this iconic cannabis variety.

It Grows Well Inside and Outside

Some marijuana strains thrive indoors, while others produce massive amounts outside. When cultivated outdoors, OG Kush is expected to produce a larger yield. To increase productivity, indoor gardeners should consider using the Sea of Green or Screen of Green approach. When grown indoors, OG Kush yields seventeen ounces per square meter on average, with a flowering duration of eight-nine weeks.

Outdoor growers can anticipate to harvest up to sixteen ounces/plant in early October. Powdery mildew attacks are the most common problem but you may counteract this by increasing ventilation. Because OG Kush is indica-dominant, it grows short and densely. This necessitates pruning.

For Indoor Growth, Consider a Hydroponics Setup

Marijuana seeds have been grown unrestricted for hundreds of years all throughout the world and is known for its hardiness. The plant has even developed numerous forms of weed to adapt to diverse climate conditions. Sativas, for example, thrive in warm climates, but indicas are native to the harsh Eurasian Steppe.

Marijuana has always been produced in soil, but in the current day, hydroponics have become increasingly common. Simply said, hydroponics is the use of an inert growing medium in place of soil. Hydroponics may have been employed in gardening by ancient civilizations, thus it is not a new concept.

Due to its vulnerability to disease when cultivated in soil, OG Kush is an excellent fit for this growing method. There are three primary types of growth medium:


Rockwool – It’s made of thin rock fibers and it is the most preferred option because to its moisture-retention properties. Before using it, put it in a pH solution of 5.5.

Clay Pellets – These thick pellets provide excellent support for your plant and help to wick moisture to the roots.

Coconut Fiber – It is the most eco-friendly alternative, and it’s also the best at holding moisture.

For OG Kush, there are various hydroponic setup choices, including:

  • Wick System
  • Aeroponics
  • Drip System
  • Ebb and Flow
  • Nutrient Film Technique
  • Deep Water Culture

If you’re growing OG Kush in a hydroponics system, keep in mind that you’ll need to make absolutely sure your plants receive adequate nutrients.

Feeding the Plants

OG Kush, like all cannabis plants, needs minerals like phosphorus, nitrogen and potassium. However, OG Kush, like all plants with OG DNA, needs plenty of calcium and magnesium to thrive. Calcium gives the plant structure and helps it survive stress.

Unfortunately, determining if a cannabis plant has a calcium shortage is difficult because it is often accompanied by other problems like iron or magnesium insufficiency.

Keep in mind that calcium flows slowly through the OG Kush plant. As a result, deficits in areas of fan leaves uv light and younger growth can be identified. Curled tips, stunted development, crinkling, dead areas, and little or unexpected new leaves are all signs to check for.

When your OG Kush plant isn’t getting enough calcium, it will show the following symptoms:

  • The stems become hollow and feeble.
  • The buds and blooms take a long time to develop.
  • Root rot becomes a greater threat to the roots.

When employing a hydroponic grow setup, calcium deficiency is a special issue. Invest in a Cal-Mag (calcium and magnesium) supplement if you suspect your plants are deficient in calcium.

Your plants can transmit magnesium from old leaves to new ones because it is a mobile nutrient. The issue with this deficit is that it might cause your plants to lose a lot of lower leaves very quickly. If the bottom leaves of your plants have yellow or bright green margins that seem crisp to the touch, you may have a magnesium shortage.

Growing at the Right Temperature

OG Kush grows best at temperatures between 65 and 80 degrees Fahrenheit. It tolerates lower nighttime temps better than other strains, although humidity levels must be reduced during flowering.

Maintain a temperature of around 80 degrees during the vegetative period. Reduce the temperature of your OG Kush to roughly 70 degrees once it has reached the flowering stage. Ensure that the temperature difference for day and night is no more than 10-15 degrees throughout the growing period.

You will shock your plants, slow it down growth, and perhaps kill the entire crop if your grow room is too cold for an extended length of time. Mold is more likely to grow in colder temperatures. It can also cause the leaves of the OG Kush plant to become purple, and low temperatures slow down photosynthesis.

Allowing your growing room temp to get above 80 degrees can be dangerous. This decreases the scent and quality of the buds by slowing bud growth as during the flowering stage. Excessive heat also raises the chance of insects such as spider mites attracting to your home. Additionally, root oxygen deficiency can cause the leaves to wilt.
