Auto-flowering Seeds

Amsterdam Seed Supply offers a large range of award-winning 'Auto-flowering' cannabis strains. When a marijuana plant is "Auto-flowering", it will flower automatically when it reaches a given maturity, regardless of photoperiod. Auto-flowering cannabis seeds are in almost all cases crossings (hybrids) between Cannabis ruderalis and Cannabis indica and/or Cannabis sativa, these Ruderalis strains come from the far east, where there are limited light hours that force the plant into flowering as quickly as possible to thrive and reproduce. As said before, they start to flower automatically, this in comparison to the 'classic' Cannabis sativa and Cannabis indica which need a reduction of sun hours a day in order to flower.

Choose Amsterdam's Legendary Auto Flowering Seeds

Auto-flowering cannabis seeds are also well suited to be grown outdoors in regions that do not have many hours of sunlight per year. Places like the northern and southern hemispheres are great to grow auto-flowering cannabis seeds since the limited amount of light will not affect the growth and flower cycle of the plant, nor will it get stressed into flowering less or interrupting the flower cycle altogether. This means that all our auto-flowering cannabis seeds will make for great balcony plants that can be planted in the spring and harvested by the end of the summer. 

Cannabis Ruderalis, the Auto Flowering Genetic

Auto-flowering marijuana seeds with Cannabis Ruderalis heritage simply start to flower when they reach a certain age. These strains originate from Ruderalis genetics that includes strains like "Low Rider" (which you might spot in the genetic make-up of many Autoflowering cannabis seeds) combined with the normal Indica and Sativa strains and are native from extreme regions of the world like Siberia. Most auto-flowering cannabis seeds start to flower around week 3 and  although auto-flowering cannabis seeds have already been on the market for a while, in the last few years, the popularity of auto-flowering seeds has skyrocketed thanks to the ease of growing them. It is the go-to plant of choice for up and coming growers that are looking to experiment with growing cannabis as a hobby.

It is possible that one of the few downsides to growing Auto flowering seeds is the little yield that they produce, compared to a feminized strain that can have its growth controlled to make it larger, Auto Flowering cannabis seeds need to be grown as quickly as possible since they will immediately begin to flower and in the worst case scenario the plant will be so small that it would have only one cola.
