These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →
Taste & Aroma Profile
Citrus and fruit with subtle hints of earth and pine, and a gassy, sharp aroma in flower — “terps are through the roof”, as one grower put it.
About Green Crack
Genetics & strain profile
Green Crack is a sativa-dominant classic — 75% sativa, 25% indica — created from a cross of Skunk #1 and Afghani. With 15 to 20% THC it is not the strongest strain we sell, but it is one of the most energizing, and its 50 to 60 day flowering time is unusually short for a sativa. It is relatively easy to grow, for novice and experienced growers alike, and it is one of our best-reviewed products: 21 reviews averaging 4.7 out of 5. Growers describe “an absolute beast of a plant” with “huge fist-sized nugs from top to bottom” and “strong, healthy, dark plants with a big yield” two summers in a row. Several reviews are about our customer service after a germination problem — we replace packs that fail, and one customer left a one-star review in 2021 when a pack did not pop, so we mention it here.
How Green Crack grows
Indoors Green Crack flowers in 50 to 60 days and can give up to 500 g/m². It is susceptible to powdery mildew, so keep the air moving, the humidity down and the canopy open; a sulphur or potassium-bicarbonate spray in veg is cheap insurance. Outdoors it is typically ready in late September to early October, with up to 600 g per plant depending on conditions — and the plant can get enormous. One 2025 reviewer reported sativa-style plants 15 feet tall and 5 feet wide at week 5 of flower, “really problem resistant”, with big buds still filling in. Give it full sun, stake it, and top it in June if you need to keep it below a fence line. Germination reports are generally good; the paper-towel method and a warm spot are all it needs.
Taste, aroma and effect
Citrus and fruit with subtle hints of earth and pine, and a gassy, sharp aroma in flower — “terps are through the roof”, as one grower put it. The effect is a burst of energy and focus, clear and motivating, which makes Green Crack a daytime strain: good for a hike, a project or a social afternoon, less good for sleep. At 15 to 20% THC it is friendly to people who find modern strains too heavy. For another energetic sativa that finishes early, see Pure Power Plant; for a citrus strain with more body, Lemon OG Kush.

Not so much a review of the seeds, but a review of the customer service. Hands down the best seed company when I comes to customer satisfaction. After just a few moments chatting with Kat, my issues were solved and they bent over backwards to ensure I was happy. Thanks again QCS absolutely great company. Wish I could give them more than a 5 star rating.

A friend of mine ordered some of these and gave me one to try. I grew it indoors and the quality of it was amazing. Very healthy plant and easy to grow. Nice dense crystal covered buds with great effects. The product description is spot on in my opinion. Would grow again.
