Growing autoflowering cannabis strains properly: Tips & tricks
What are autoflowering varieties?
Spring is here, the days are getting longer, the temperatures are rising and the growing conditions for the outdoor grow are getting better and better. In northern / cool regions it usually takes longer before you can start with outdoor cultivation. Autoflowering varieties are now an excellent option for many growers to harvest their own buds even with little space and in a short time. In our following article you will learn everything about the cultivation of autoflowering varieties. But first a little background knowledge …
Rapid flowering photoperiodic cannabis plants will not be ready until mid-to late September, depending on the climate. The „Fast Version“ varieties can often be harvested outdoors as early as the end of August/at the beginning of September. This, too, of course, depends heavily on your growing climate and other growing conditions. Photoperiodic cannabis plants, also Fast Version varieties, start flowering only when the days and thus the hours of sunshine per day get shorter.
It’s very different with the autoflowering strains, which often stay smaller and don’t achieve as high yields as their big sisters the photoperiodic cannabis strains. However, you can harvest with them already about 2 months after germination. Automatic varieties take up little space, are perfect for growing on the terrace or balcony and start flowering regardless of the daily light hours. This allows 2-3 harvests per season, depending on the climate.
After a short vegetative phase of 2-4 weeks, autoflowering varieties begin flowering by alone. The cannabis growers matched genes from cannabis ruderalis, a cannabis type with autoflowering properties, with other cannabis strains. The crossing of autoflowering ruderalis with indica or sativa varieties produced strains that can bloom independently of daily hours of sunshine and have a short compact structure.
Some autoflowering strains of the latest generation can reach a considerable size and thus also increased yields.
The growth phase of autoflowering varieties lasts about 25 days. Then the plant begins to bloom and can grow in size until the 40th day. From then on, the increased flowering growth sets in, the buds become bigger and denser.
The benefits of autoflowering varieties
- Autoflowering varieties start flowering outside automatically regardless of the hours of sunshine per day. This means you don’t have to worry about extra lighting that makes up for too little light, or a „relapse“ into the growth phase during flowering, causing loss during harvest and often creating strange growth (twisted leaves, altered Bin shape ..).
- You can earn 2-3 outdoor harvests per year. Indoor and outdoor can be harvested faster and more frequently.
- Many automatic varieties remain smaller than photoperiodic plants and are therefore easier to hide and notice less. They are perfect for growing in small growboxes or gardens.
- Self-flowering cannabis strains are easy to grow, don’t require much prior knowledge and make little claim.
In recent years, autoflowering genetics have been steadily improved, especially in terms of potency and effect. Numorate different Automatic varieties were launched, allowing each grower to figure out their favorite strains.
Cultivating Automatic cannabis strains
Automatic varieties are only a short time in the growth phase, sometimes only 2 weeks. So time is limited to do pruning or further training methods. With the help of topping, you promote the formation of flowers. Once the plants have three pairs of leaves, you can start topping. Another low-stress method is tying up the main stem, allowing side branches to grow more upwards and form an equal carpet of flowers. Once the Automatics have started flowering, you shouldn’t do a topping. You can prune them up to a maximum of one week in the flowering period.
In principle, however, autoflowering varieties should be pruned as little as possible. In the short vegetative phase they have only a limited time to recover and they need all their energy for the short flowering period.
Automatics get the best outdoors when they get as much sunlight as possible. The best outdoor growing time is from spring to high summer. With good planning and depending on the climate, you can reach 2-3 harvests per season with autoflowering varieties. Indoors, you can achieve the highest yields with the lowest wattage with the help of NDL-or LED lighting. However, it is also possible to grow Automatics with luminous tubes or energy-saving lamps and many growers achieve satisfactory results.
The ideal indoor lighting duration is 18/6-18 hours of light and 6 hours of darkness.
However, autoflowering plants can also be easily illuminated 24 hours a day. However, this also costs more energy in the house.
The growing conditions
Offer autoflowering varieties in their short growing season the best conditions to get the best results. This means: Pay attention to a good planting medium, moderate and not too intense fertilization, ensure that sufficient sunlight is available, avoid stress due to dehydration, overwatering or other factors, etc.
Use a natural Root booster In a weak dosage to promote root formation. Fertilizer for the first time from the 20th day of life with a growth fertilizer and from the 30th day of life with flower fertilizer. From about the 50th day of life, just pour water to wash out excess fertilizer salts.
The planting pot
Plant sprouted automatic seeds directly into the plant pot with the final size. The pot in which they will stay until the harvest. Planters with at least 11 litres are best suited, larger pots of 20L or 25L are even better. This prevents the plants from having to overcome the overpot stress in the short growing season and first make a freeze on growth. In this way, they can grow without disturbances and interruptions to reach their maximum size until flowering. Larger plants can yield higher yields. This is also the case, especially, in autoflowering cannabis strains.
The perfect soil
Autoflowering varieties like air-permeable, loose planting soil that contains little nutrients. Above all, it is suitable for Light Mix With little added fertilizer. You can also loosen up the Lightmix by adding Vermiculite or Perlite . The pH of the soil should be 6.3-6.5, similar to photoperiodic plants. Finished earth mixtures for cannabis plants already have the right pH.
The ideal harvest time for autoflowering varieties
To achieve optimal results and achieve buds with as high THC as possible, you should harvest when 50-70 of the haideries have turned brown and most trichomes are milky. With a small Microsoft Or a magnifying glass you can easily recognize the trichomes.
Plan the Automatic Grow
Prepare the next cultivation of autoflowering plants in good time. If you germinate new seeds before the current Grow is harvested, you can achieve a continuous harvest.
In the meantime, you will find a wide range of high-qualityand productive autoflowering cannabis strainsat numerous seed banks.
