Autoflower Seeds for Sale

Autoflowering seeds are modern cannabis hybrids of the Ruderalis species of Cannabis plants. Autoflower strains transition from the vegetative growth stage in to the blooming stage automatically. This tends to occur four to six weeks from planting the seeds. Many auto flower seed strains will be ready to harvest in less than 10 weeks from seed.

Autoflower weed seeds grow well indoors and out, and come in both feminized auto and regular auto flowering varieties. Feminized Auto Flowering Cannabis Seeds are specifically bred to become all female with no production of males, while regular autoflower marijuana seeds will produce 50/50 male to female ratio.

Like most plants, Cannabis regulates its growth cycles according to the amount of daylight it receives. As the days get shorter, the plants acknowledge their need to propagate before winter arrives. This forces the plants to mature and develop their reproductive organs in the hopes of making seeds for future offspring. That is how photoperiod flowering marijuana strains work. However, Autoflowering varieties are different.

What are Autoflower Cannabis Seeds?

Autoflowering cannabis plants follow a measured timeline for their entire duration of growth. As soon as the seeds germinate, they adhere to a strict schedule pre-designed by genetics. The plants develop based on maturity instead of photoperiod. Autoflower strains began with the Ruderalis subspecies. Ruderalis differs from Sativa and Indica plants in that they are low profile sized plants that will enter and complete the flowering phase regardless of available daylight hours. Ruderalis grows wild between Eastern Europe and Central Asia, with a high distribution in Russia.

Modern Autoflowering strains are hybrids of Sativa, Indica, and Ruderalis genetics. Breeders carefully select phenotypes that adhere to the auto-flowering criteria. The cannabis marketplace has seen a dramatic upsurge of Autoflowering strains due to significant quality increases. Autoflower strains commonly grow from 12-24 inches (30 to 60cm) tall and yield about 0.5 - 2 oz/plant. Most Autoflowers will go from seed to harvest in 8-10 weeks, considerably faster than standard indica or sativa varieties.

Why Use Autoflower Seeds?

Autoflower marijuana strains are easy to grow, faster to flower, and tend to tolerate harsh weather and pests better. Commercial and small-scale growers can both appreciate the benefits of producing fast-growing crops of forgiving plants. Growers often choose Autoflower strains because they can achieve more harvests per season and also because the autos are well suited for perpetual harvest growing. Another distinct trait of Autoflowering plants is that they remain low profile and thus are a good option for stealth growing outside or in indoor gardens with limited vertical grow space.

How to Grow Autoflower Seeds

Autoflower Cannabis seeds start the same way as all cannabis seeds. We recommend following the How to Germinate Cannabis Seeds article. After the seeds have successfully sprouted, you can prepare your pots. Because auto-flowering strains do not easily tolerate transplanting, the Air Pruning method is advised to help to manage the roots if you are planning to eventually transplant them outside. Once the taproot reaches the bottom of the container, it will signal flowering for the plant. The Air Pruning method helps keep the roots from making that connection and makes it easier to transplant outdoors.

For indoor gardens, it's best to use the same container you wish to flower in for the whole growth cycle. You can prepare the flowering pot by placing about 1 inch of damp coconut fiber and perlite in the bottom of the container. This combination helps to air prune the roots and ensure a healthy rhizosphere. You can then fill the pots with your substrate. Generally, a lighter and more airy substrate is best for autoflower strains. Before placing the germinated seeds in the soil, a light sprinkling of root inoculant or stimulant can be used to help provide a rich medium for root growth. Then carefully place the germinated seeds into the soil. Cover them with a light layer of substrate and gently hand water. Take care not to overwater them.

Autoflower plants tend to become stressed from overwatering much faster than photoperiod flowering strains. It's best to let the soil dry out between waterings instead of feeding them when they are still damp. Pick up the plants to feel the weight of the pots in order to judge how much water may still be present. Or stick your finger into the soil to feel how dry it is. Another way is to watch the Turgor Pressure of the plants. When they start to slouch it means that the cells lack water and the plants are ready for another feeding.

For indoor gardens, Autos will flower under anywhere from 12-18 hours of light. You can adjust this schedule according to the needs of other plants in your garden at the time. Most autoflower varieties will finish flowering after 10 weeks from showing their first true leaves. Auto strains do not handle topping or training well. It's best just to let them grow vertically. Pay attention to the trichome development like with traditional strains. Often the main cola will finish before the side branches so you can progressively harvest as the buds develop. Some auto strains with more Sativa genetics can take longer to ripen than Indica or pure Ruderalis ones.
