This cultivar’s popularity also increased accessibility. You can now buy Green Crack seeds and see its legendary traits develop in your garden.
The i49 Genetics library stocks the feminized variant to ensure everybody gets smokable marijuana for as little trouble as possible. Our seeds develop into female plants 99% of the time. The risk of pollination reduces, and your resources only go towards future buds.
Here’s a quick guide on cultivating Green Crack feminized seeds. Most tips apply across the board but look into the specifics if you pick a mixed breed instead of the original.
Preferred climate & Green Crack plants
Green Crack seeds have a sativa-dominant genome. Their plants love the hot weather and dry air of the Mediterranean and Continental regions.
This strain is very adaptable, resisting weather imbalances with ease. Most parts of the States are suitable for outdoor cultivation. Regardless, keeping crops warm and dry prevents growing troubles like mold and bud rot.
Take your Green Crack seeds outdoors in late April, when there’s no more lingering frost. Plant them in a sunny, breezy spot and let the summer sunshine ripen them to perfection. Outdoor temperatures remain adequate till mid-October.
Want to grow Green Crack feminized seeds indoors? Replicate their optimal climate to make them happy and healthy. As a rule of thumb, keep your grow room at:
- 70–79°F for vegging, 68–75°F for flowering (around 10°F lower during lights-off hours)
- 50–60% relative humidity for vegging, 40–50% for flowering (reduce it to 35% two weeks before the harvest)
Use strong full-spectrum lamps to replicate natural sunlight. Employ ventilators and exhaust fans to imitate the breeze of outdoor environments.
Tip: If growing an indica-dominant type of Crack seeds, drop air humidity to below 50% in late vegging to prevent mold issues.
Feeding Green Crack
Once your Green Crack marijuana seeds go past the seedling stage, it’s time to provide water and nutrients. Like most sativa strains, this cultivar is prone to overwatering and nutrient burn. Tread with care to prevent health issues.
Use 5.8–6.8 pH water. Only soak crops when the ground is dry. Every other day for vegging and every third day for flowering is usually a good idea, but check the soil before delivering another shower.
A well-balanced NPK solution is ideal for plants from Green Crack seeds. Skip the chemical fertilizer and choose additive-free nutrients or organic materials for your feeding schedule.
Green Crack isn’t a particularly hungry plant in the vegetative stage. Provide light nitrogen amounts once a week. It gets ravenous in flowering, so boost phosphorus and potassium in blooming. Stick to weekly feedings, but increase the quantity.
Plants from Green Crack seeds aren’t prone to nutrient scarcities, so steer clear of micronutrient supplements. Add them only if there are clear signs of a deficiency.
Flowering & yield
Once you reduce the light schedule to 12/12 or days get shorter in mid-August, plants from your Green Crack seeds enter flowering. It’s another 7–9 weeks before you collect the sticky buds.
Note: The flowering times for versions of this strain vary, but they’re generally around eight weeks.
Your crops first go through a growth spurt. They might double in size in the first flowering week. Then there’s no more branch and foliage production—it’s all buds for the next two months.
Water Green Crack feminized seed-grown crops once every three days and feed them with phosphorus and potassium. Check the plant sex to eliminate accidental males and ward the grow area off external pollinators for seedless buds.
After about a month, real flowers start adorning the plant structure. They’re small and chunky, green at first and yellowing as they ripen. A sprinkling of trichomes arrives soon after, emanating strong fruity scents.
Inspect the buds from Green Crack seeds for ripeness to pinpoint the ideal harvest window. The trichomes should turn opaque, and the pistil hairs rusty and curled inward by week nine. You notice these signs in mid-October outdoors.
Besides quality, this cultivar delivers quite a quantity. Expect to collect 17–21 oz./m² in indoor setups. Each outdoor crop yields over 21 ounces of bud.
