The smell is unbeatable. The strain shows prodominant Indica characteristics during growth with a high resin count and heavy, potent harvests and a fast flowering time of 8-9 weeks.
Give it a whirl indoors or outdoors and you’ll be rewarded with some of the finest. Make sure your Grapefuit receives maximum light exposure and a high EC of 2.0 – 3.0 for best results.

- Although an earthy flavour is certain no matter the strain, but with Grapefruit, the sour taste reduces the ashy hit. Your tongue will be lit up by the juicy, sour flavour which can been compared to a spicy tea.
- Grapefruit bud is minimally dense and fluffy and has a light green colour with peach pistils.
- The high you get from Grapefruit comes fast and strong, giving users an energy and a boost in mood. It is also an aid to inspire creativity, as well as benefit stress and migraine sufferers through its analgesic effects.
- Grapefruit is versatile and grown indoors or outdoors. Expose your plant to a warm and humid setting akin to a Mediterranean climate if grown outdoors.
- If grown indoors it is a short plant that will likely grow no more than 3 feet tall created a moderate yield and can make it more valuable, often found on the top shelf in dispensaries.
- Grapefruit loves a sunny and warm environment.
- When growing 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. Grapefruit loves a fertile soil, whether growing indoors or outdoors. Be sure to prune your plant when growing indoors as it can grow quickly
- Also remember to keep an eye on the humidity levels of your plant. This strain should be kept at around 65-70% humidity during the vegetative stage and lower this by 10-15% in the flowering stage. Drop the humidity down an extra 5% during the nights of the flowering stage.
- Grapefruit typically takes around 8 to 9 weeks to flower, and you can expect to see around 600 grams for every plant when grown outdoors. When growing indoors you could see 400 grams per square metre.

- 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..
- Your Grapefruit 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.
- 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.
