Genetics

Indica or Sativa

Purple Kush Autoflower is an indica. The original Purple Kush comes from Hindu Kush and Purple Afghani, both indica landraces. This autoflower version adds ruderalis genes, so it flowers on its own. The plant grows short, squat and bushy, with broad leaves and dense buds. Cool nights can turn it deep purple. For a home grower, that classic indica shape is ideal for a tight spot. It puts its energy into density, not height, so it fits a closet or a small tent. Indoors, a 20/4 light schedule (or 18/6) works from start to finish.

Difficulty

How Hard Is It to Grow?

Easy. Autoflowers flower on their own as they age, so there is no light schedule to manage. Sun, water and Superb Soil do most of the work. Indoors, keep lights on 18/6 or 20/4 the whole grow.

Purple Kush Strain: Type, Aroma and Flavor

Purple Kush in flower

Purple Kush Autoflower is a feminized indica, one of the classic indica strains, and everything about it says indica: broad leaves at every stage and a short, squat shape. The nose is one of the best in the garden: earthy sandalwood and sweet grape candy, with floral pine and a little spice. The loudest terpenes are myrcene, caryophyllene and linalool. The flavor reads earthy and spicy, with a sweet grape undertone. Purple strains are known for their nose and bag appeal, and this one delivers: in cool weather the buds and leaves turn deep violet and plum.

How to Grow Purple Kush Autoflower Seeds in a Pot for Pot Kit

Plant one seed in our organic super soil and just add water. It’s a super easy plant: all it needs is soil, water and light, and the plant does the hard work while you watch it grow. It’s an autoflower, so it runs on its own internal clock; you never change the light schedule. Indoors, a 20/4 schedule (or 18/6) works from start to finish. It’s a squat bush that puts its energy into density, not height, so it’s happy in very small spaces, from a closet tent to a converted computer tower. Be gentle with an autoflower: skip topping, because it has less time to recover than a photoperiod like OG Kush. Instead, gently tie down the main stem (LST) to open up the side branches. Our step-by-step guide to growing a small weed plant walks you through it. Growing in one of our kits? Free email grow coaching at help@apotforpot.com helps you from seed to harvest.

Purple Kush Flowering Time and Plant Size

Autoflowers run on their own clock, so you can plan the whole grow from the day you plant, and the harvest doesn’t depend on the sun’s angle. In our Indoor 2 Gallon kit, plan on as little as 80 days from seed to harvest. A short grow also uses less electricity and fewer nutrients than a big photoperiod plant. Purple Kush stays short and squat, which makes it one of the best fits in our lineup for a small pot or a tight space.

Growing Purple Kush Indoors vs Outdoors

Outdoors: it traces back to the Kush mountains and is tough. It grows well across the US and handles cool weather better than most because it finishes fast, which makes it a good pick for colder areas, or for an early or late outdoor run when cool temperatures bring out the purple. Give it at least 6 to 8 hours of direct sun a day (how much sunlight cannabis needs). Its short shape fits right into a vegetable garden. The buds get very dense; the resin coat helps it resist mold, but still give it a breeze. Find your zone on the USDA Plant Hardiness Zone Map; it’s in our Cold and Warm zone collections.

Indoors: for the deepest purple, let night temperatures drop to around 60 to 65°F (15 to 18°C) for the last two weeks; that breaks down the green and reveals the violet and plum.
