autoflowering cannabis seeds

When growing in soil, the optimal pH level of your water/nutrient solution is 6–7. You can adjust your water to the correct pH level using natural pH “up” or “down” products.

Autoflowering strains are created by crossbreeding indica or sativa plants with ruderalis. Ruderalis is a wild subtype of cannabis that grows in regions where the summer is very short but features many hours of daylight (e.g. Northern Europe or Siberia). These plants have evolved to not rely on daylight hours to flower, instead flowering according to age.

Here are some of the most popular autoflowering varieties based on well-known cannabis strain families.

What kind of nutrients do autoflowers need?

It depends on the strain. But in general, autoflowers will be ready much quicker than feminized photoperiod cannabis. The average life cycle of autoflowers is about 10 weeks, with some strains ready as soon as 8 weeks after germination.

Renowned for their sweet berry notes is the famous “Blue” family of cannabis. Originally from the US West Coast, Blueberry has been infused into two popular RQS offerings: Haze Berry Auto combines Haze Berry and Blueberry Auto, while Bluematic is the automatic variant of the original Blueberry.

Keep your grow room’s temp at a moderate 21°C (room temperature) for healthy growth. Colder temperatures or excessive heat can lead to growing problems. For best results, grow in an environment where you can maintain full control. Use heating and/or cooling if necessary.

Autoflowers also need much less time to grow. Some varieties are ready to harvest in a short 8 weeks after sprouting. Plus, autoflowers are compact, which makes them great for indoor growing. Because they are so convenient, autoflowers are (not just) ideal for beginners to cannabis cultivation. More experienced growers can also take advantage of the unique growing traits of autoflowering cannabis.

The advantages of automatic cannabis seeds

Grown outside, automatic seeds can produce two or more crops in the course of a normal summer. Under lights, ‘autos’ can go from seedling to fully mature plant in as little as 10 weeks. As an added bonus, most are also very hardy and resistant to fungal infections, mould, pests and even frost, due to their extremely robust, northern Eurasian genetic lineage – the Ruderalis – that evolved the ability to flower at will in order to survive. Seeds that automatically flower can be grown indoors, out of doors or in a greenhouse. In addition, all seeds in this category are feminized and from a wide range of genetics, offering different kinds of flavour, aroma and effect.

Autoflowering seeds, on the other hand, are able to complete their life cycle regardless of how long the days are, although at least eighteen hours of light will give the best results. Unlike regular seeds, ‘auto’ seeds grow crops that do not need to undergo the usual cycle of 12 hours of light alternating with 12 hours of darkness in order to bloom successfully, whether they are indica, sativa or hybrid. They seem virtually immune to light pollution, tolerating irregular and unpredictable periods of light and darkness with impunity. Outdoor gardeners with short summers can wait until the warmest weeks to cultivate their automatic cannabis seed crop, safe in the knowledge that most of these hours will fuel the flower production, not the vegetation, period.

In terms of turnover, these seeds are capable of producing reasonably sized yields even with a less intense light source. However, the general rule that the greater the light intensity, the better the results, holds true here too. It should also be remembered that how much these types will give is governed by the final size of the plant – a windowsill crop of virtually dwarf cannabis is never going to produce as much as it would in large pots under high-intensity light. In general, however, the amount of bud eventually gleaned from seeds in this section is favourably comparable with that of regular or feminized seeds from the same variety.

How is cannabis able to flower automatically?

Feminized autoflowering cannabis seeds are easy to cultivate: They flower without the need to change light cycles or remove males. Automatic seeds are ideal for new growers, and for those who want a low-maintenance growing experience. Sensi Seeds’ sativas, indicas and hybrids (high THC or high CBD) are ideal for medicinal and recreational cannabis users alike.

That doesn’t mean, however, you can just throw your autoflowering seeds in the soil and hope they’ll grow as you watch re-runs of Bong Appétit . Indeed, since these plants flower so quickly, you need to be on top of your autoflowering seeds.

Let’s be frank: people in the 21st century have no patience . Whenever we want something (especially cannabis!), we want it right now. Many home growers don’t want to invest the time it takes to grow an average indica or sativa strain of cannabis. Yeah, yeah, it’s probably true that “enduring patience is the highest austerity,” but there’s nothing wrong with wanting to speed the weed process. Luckily for impatient cultivators, there is an easy way to cut your total growing time down to about ten weeks: invest in autoflowering seeds.

One of the biggest bummers with using autoflowering seeds is that they don’t yield as much as other cannabis seeds. No matter how much light you give your plants or how well you train them in the vegetative stages, they won’t produce as much as a standard cannabis plant.

Avoiding Nosy Neighbors

As the name suggests, autoflowering seeds flower automatically (duh). That means these plants go through a rapid vegetative stage before moving into the flowering phase. Besides their speed, many growers are attracted to autoflowering seeds because they don’t require set amounts of light/darkness and they produce short plants that are easy to hide.

Of course, since autoflowering seeds aren’t reliant on light, that also means you could plant these seeds any time within the standard growing season and get a good result. So, if you want to make a quick batch of cannabis late in the season, consider going with an autoflowering strain.

As you could see from the info above, autoflowering seeds don’t require as much maintenance as other cannabis strains. This is great news for beginners who don’t understand nuanced issues like light cycles and nutrient distribution.

In nature, light cycles are an extremely important part of plant growth. Vegetation usually happens when days are longer. Cannabis plants have evolved to grow and flower in sync with the passage of the seasons. If you are growing outdoors, your cannabis seeds must be sown around early summer in order to be ready around the autumn (when days get shorter).
