What are the characteristics of Sativa autoflowering seeds

These are all Sativa-dominant strains that will automatically flower, no matter the daily lighting schedule, and go all the way from seed to harvest in around 10 to 12 weeks!

  • Sativa dominant strains offer a more cerebral, energizing high compared to their Indica cousins. They are great for people looking for a boost of creativity and focus. The uplifting and euphoric effects that Sativa dominant cultivars bring to the table make all of these strains perfect for daytime use.
  • The term "autoflowering" refers to the plant's ability to automatically switch from vegetative growth to flower production without needing a change in lighting. Photoperiod strains need 12 hours of darkness each day to start flowering, but with autos, this process happens automatically no matter the lighting schedule.

How much do autoflowering Sativas yield?

Sativa autoflower seeds can produce around 400 - 500 grams per square meter when grown indoors. Outdoors, they can hit up to 200 grams plus per plant.

Autoflowering seeds are great for indoor perpetual harvest grows. Thanks to the simple lighting requirements for autos, you can have a never-ending supply of fresh buds without worrying about light schedules or separate grow areas for different growth stages.

What are the effects of Sativa autoflowers?

Think of Sativa’s as the energizer bunnies of the cannabis world. Most people have this idea that weed is something that makes you feel relaxed and lazy, but Sativa autoflowers are different. They provide a more stimulating and inspirational high, perfect for socializing or getting creative.

How do you grow Sativa autoflower seeds?

Our range of Sativa autos work great both indoors and out under the sun, but to get the most out of your crop, there are a couple of things to keep in mind.

  • Select the right genetics for your environment: Outdoor growers will need to be a little more picky about which strains to grow, and it's important to consider your climate, weather patterns, and available space when making your selection. If you are planning to grow indoors, and have full control over the growing environment, then you can go for pretty much any Sativa auto you like!
  • Start with the right pot size: Autos only have few short weeks of vegetative growth, so it's best to start them in their final pot to cut out any chance of transplant shock. For most autos, a 3-gallon pot (around 12 to 15 liters) works great.
  • Light it up: Most growers stick to a lighting schedule of either 18/6 or 20/4 for autos, but some may even opt to give 24 hours of light per day. Find what works best for you and your plants.
  • Nutrients: Autos tend to need a lighter dose of nutrients than photoperiod strains, so be careful not to overfeed them. Start with a lower concentration and gradually increase as needed.
  • Low-Stress Training (LST): You don't want to stunt your Sativa autos growth, so steer clear of HST techniques and opt for LST instead. Gently bend and shape your plants, maximizing space and light exposure without causing too much stress.
  • Screen of Green (ScrOG): A low stress cultivation technique where a screen is used to help support and spread out the branches and buds, allowing better light penetration and increased canopy air exchange.
  • Harvesting: As these plants tend to have a more energetic high, it's best to harvest them when the trichomes are mostly cloudy with some amber. This will give you a balance of both uplifting and relaxing effects. The longer you leave them, the more the trichomes will turn amber, resulting in more Indica like effects.
  • Drying and curing: Properly drying and curing your buds is crucial for preserving flavor, potency, and overall quality. Hang dry your buds in a dark and cool place with good air circulation for 7 to 10 days before transferring to jars for curing. Open the jars daily to release any built-up moisture and allow for proper curing. Once cured, enjoy your flavorful and potent Sativa autoflower buds!
