OG Kush Feminized Growing Information

This classic marijuana strain has relatively little info about its precise origins, but some say it could be derived from the strains Chemdawg, Hindu Kush, and Lemon Thai. Popular on the West coast of the US, and indeed, around the globe, OG Kush is a stress busting strain, with a distinctive skunky, and spicey aroma.

OG Kush is the parent of many other well-loved cannabis strains, such as Girl Scout Cookies. There are also several phenotypes derived form this strain, such as Tahoe OG, SFV OG, and Ghost OG.

Aroma, Flavour & Appearance

  • OG Kush has complex aromas and tastes, and smells somewhat like fuel, spice and earthy, with a similarly lemon-spice taste, as well as pine and hints of citrus.
  • The appearance of OG Kush is the classic cannabis bud look, with natural green coloured leaves, bright yellowy-green sugar leaves and green and orange pistils.
  • The high THC levels in this strain ensure there is a good coating of trichomes, giving this strain lovely snow-covered look.

Effects & Usage

  • This strain will give you a full body high, which will make you feel both deeply relaxed and give a punchy euphoric sensation. The balanced high will uplift you but also allow a sense of calmness and tranquillity to wash over you, giving a fairly strong coach-locking sensation, and also the munchies!
  • High doses of this could lead to dry mouth and eyes, as well as dizziness and paranoia (although the latter is mostly for beginners). When trying a high THC strain for the first time, always start in small doses.
  • OG Kush is a great strain for those seeking some medicinal benefits and is known to help with a variety of ailments. It can help with inflammation, sleep, pain, stress, and depression. If using for a mental condition, do not overdo it as too much THC could lead problems to actually worsen.


  • OG Kush can be a moderately difficult grow due to its susceptibility to powdery mildew, mites and other pests.   You will likely get best results growing this strain outdoors if you’re in a hot climate.
  • Indoors, just ensure you monitor the environment and keep a close eye on pests and disease so you can act quickly to rectify before it becomes a problem.

Best Climate

  • OG Kush prefers hot, or tropical environments, but can handle lower evening temperatures. Keep the temperature at around 26.5 degrees Celsius during the vegetative stage, dropping to around 21 degrees Celsius whilst flowering. Night-time temperatures can drop to 10 degrees below daytime temps.
  • Make sure the humidity goes no higher than 55% during the vegetative stage and gradually lower it during flowering, down to around 40% humidity.

Indoors or Outdoors?

  • OG Kush will only do well outdoors if you live in a hot or tropical climate. If not, then you can easily grow it indoors, and it does particularly well in a hydroponic system growing with an 80/20 mix of coco coir to perlite.   This growing medium ensures adequate moisture and oxygen at the root zone.   As always, ensure you have the right type of nutrients.

Flowering, Yield & Harvest

  • OG Kush has a flowering time of around 8 weeks. You might see a harvest of 500 to 550 grams per plant growing outdoors, or 425 to 475 grams per square metre indoors. Plants will grow short and compact and produce an average yield.
  • When growing outdoors in the Southern hemisphere you’ll start your plants in September and likely be harvesting Dec then repeat!   So you can expect multiple harvests per season after re-planting

  • All Cannabis strains, require a full spectrum nutrient complete with the macro nutrients such as Nitrogen, phosphorus, and potassium and the secondary nutrients and micronutrients like, calcium, sulphur, hydrogen, magnesium, manganese, carbon, iron, zinc etc.
  • Cannabis are big feeders!  Make sure it has all the nutrients it needs, particularly in the flowering stage, to help the buds become dense. Using soil is slightly more forgiving if you overdo it with the nutrients. If you are using a good quality soil, it will have a lot of nutrients in there already, so there is no need to add any during the seedling stage.
  • During the vegetative phase you will need to give your plant twice as much nitrogen as phosphorus, and three times more nitrogen than potassium. The nutrient ratios to look for on the bottle will be either 6-3-2 or 18-9-6. You should also add in some sulphur, magnesium, and calcium.  
  • During the flowering stage, change the ratio so you are using up to three times more phosphorus than nitrogen and potassium. Also continue to add in secondary nutrients such as iron, copper, and manganese.  Make sure to use orgnanic Bud Burst during flowering all the way as this will ensure a smooth finish with no chemical taste.   Amazing stuff!
  • For organic grows, we recommend Aptus Baseboost organic nutrient   with coco/perlite 70/30 ratio.   This stuff is highly concentrated so a little goes a long way making it great value.     Simply add the pellets to the coco as per the instructions and it will completely transform any inert growing medium into a powerful full spectrum grow media.. 

Growing Tips

  • Some growers like to expose their OG Kush plants to enhanced levels of CO2, in order to get bigger yields. The air should hold 1200-1500 ppm of CO2 for this method to work, and you do this by using a CO2 generator. This can also strengthen the plant to resist higher temperatures, up to 35 degrees Celsius.
  • Bud rot & powdery mildew are two problems that growers can face when growing OG Kush.  These diseases can be prevented by ensuring plenty of ventilation if indoor and if outdoor, plenty of sun and less water during high humidity and rainy periods.

Why buy ‘Feminized’ Seeds

  • Marijuana plants are either male or female.   The male flower produces sacs or pollen designed to fertilize the female flower which produces white pistols designed to absorb the pollen.   If no male plants are present in the growing area, than the female plant will just grow larger and larger flowers in search of pollen.   These flowers are the cannabis buds that we all know and love.   The male plants hold only minuscule amount of THC, while the female flowers are oozing with THC crystals (the good stuff).   For this reason, marijuana growers are seeking only female plants in the grow room (unless they want alot of seedy buds).Feminsed seeds have been cultivated in a precise way so that the seed is genetically more likely to produce a female plant.   Autoflower seeds automatically transition from the vegetative phase to the flowering stage without you needing to adjust their light exposure.   Fore more detailed growing information, see our in depth grow guide.
