Best Climate

  • Due to Master Kush’s preference for jungle-like weather conditions, you would think that you would need to keep the temperature quite warm. However, this is not always the case.

  • Master Kush handles temperatures from 18-26 degrees Celsius. 

  • When grown indoors you may be surprised how low you can keep the humidity levels.

  • Outdoors a sunny and warm environment is often best.

  • outdoors, you must make sure you have to time to prune and tame your plant, or you may find it getting out of control! Because it flowers a little later, ensure your climate stays warm into April and May (Southern hemisphere) or October and November (Northern hemisphere).

  • If growing indoors, you will need some strong grow lights and a dry room, with little humidity. Grand Master Kush loves a fertile soil, whether growing indoors or outdoors. Be sure to prune your plant when growing indoors as it can grow quickly.

Flowering, Yield & Harvest

  • Grand Master Kush typically takes around 8 to 9 weeks to flower.
  • Check out our Aussie grow calendar for when to harvest outdoors in Australia.


  • 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.
  • For coco/perlite grows, we recommend Nutrifield Coco A&B for use throughout the entire grow, with Nutrifield Organic BUD BURST at the beginning of the flowering phase right through to harvest.  As bud burst is organic, this ensures a nice smooth, super clean tasting smoke that you will love!
  • For soil based growing (not recommended), just make sure you use a high quality soil rich in organic matter such as compost and manure.   Note that manure if high in nitrogen which you’ll want to reduce during the flowering stage. 
  • 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.  The best way to do this is simply 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

  • Your Grand Master Kush plants will need consistent air flow and good ventilation, whether you are choosing the perfect spot for an outdoor grow, or are growing in an indoor grow room. They need air that is rich in oxygen, to help prevent respiration, deter any pests, and allow your plant to grow healthy and strong. Use fans to help circulate air, or if you can afford it, exhaust systems are an excellent choice.

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.
