Growing Tips for Grapefruit Kush
Grapefruit Kush is a novice-friendly strain of cannabis that is easy to grow and offers a shorter flowering time than other similar strains. Grapefruit Kush marijuana plants will thrive indoors and outdoors, but have an easier time growing indoors because of the ability to completely control the climate. If you choose to grow indoors, you will have to replicate a steady environment similar to the climate of the Mediterranean. Grapefruit Kush cannabis seeds produce plants with smaller buds of green and pink. These vibrant colored plants are a standout in a sea of cannabis cultivars.
If you choose to grow outdoors, you will need to hope for consistent temperature and humidity to grow these plants to completion. Doing so will ensure that you grow healthy buds from the top of the plants to the buds closest to the soil. Having access to a greenhouse is the best way to give these plants the perfect outdoor climate without having to put up with unexpected outdoor variables. These plants grow to a short to medium height and can reach a height of around 3-7 feet. Because the plants reach a maximum indoor and outdoor height of around 7 feet, they may require a little more vertical space than smaller plants.
The ideal temperature for these plants is around 70-80 degrees Fahrenheit and slightly cooler at night. Humidity levels should be kept around 40-70% during the vegetative growth stage and the flowering stage, but lowering the humidity every week will help this plant grow. Growing indoors will ensure that the moderate humidity levels and moderate temperatures are consistent and maintained every day that the plants are in the growing stages.
Topping, Screen of Green (ScrOG), and Low-stress training (LST) methods are the best training techniques for this particular strain of cannabis. If performed correctly and at the right time, these techniques will promote bud production and increase final yields. LST helps manipulate the plants by tying down the branches to increase the size and density of the buds while allowing them to grow almost naturally. The Screen of Green method will reinforce the heaviest bud sites with screens or mesh wires so that the plants don’t bend or break under their own weight. Topping will help keep the plants manageable by trimming the tops so the canopies don’t overgrow. The Grapefruit Kush strain requires an 18-20 hour light cycle to reach the vegetative growth stage. Changing the light cycle to a 12/12 cycle will help to induce the flowering stage of growth and get your plants to harvest.
Yields, Flowering Time, and Harvest
- Flowering Time: Growing indoors, you can expect the Grapefruit Kush strain to harvest after a short flowering period of 50-60 days.
- Yields: While Indoor yields are around 550 grams per square meter, outdoor grows typically produce up to 700 grams per plant. These massive yields will provide you with a healthy harvest of high-quality buds.
- Harvest: Outdoor growers can plan on harvesting their yields around the beginning of October, depending on when the seeds were planted.
Grapefruit Kush: Sweet Fruit
The Grapefruit Kush cannabis strain terpene profile is directly responsible for how the plant smells and tastes, and the strong effects it has on its users. The most dominant terpene in this strain is limonene, while myrcene and pinene are the secondary terpenes.
- Limonene: Most Dominant – Limonene is found mostly in the rinds of citrus fruits such as lemons and oranges.
- Myrcene: Secondary Terpene – Myrcene is earthy and found almost exclusively in cannabis plants.
- Pinene: Pine Needles – Pinene can be found in conifer trees, pine needles, and cannabis plants and is known for its fresh and pine-like fragrance.
