Autoflowers are varieties of weed that don’t depend on specific hours of light or dark to grow and bloom in the same way as photo dependent cannabis varieties. Automatic strains start to flower as soon as they achieve sexual maturity and this can occur as early as 3 or 4 weeks after they have germinated. The genetics come from Ruderalis which evolved in northern Russia, where light conditions are very different to plants originating in the Kush or Latin America.
The fastest autoflowering strains are those that thrive in just 35 days. The issue with these types of cannabis plants is that they don’t have growing time to achieve a good size before they start the flowering phase, so they are often quite small compared to photo-dependent strains. Although if you are growing indoors and have limited space, this negative is actually an advantage!
Nevertheless, it is possible to experience several harvests in a relatively short space of time so autoflowers will always be popular with those who are impatient to reach harvest, especially for those living in the northern hemisphere with cold, short summers. In fact, it is even possible to have perpetual harvests if you plant seeds as soon as one batch starts to flower. Autos also often have better resistance to diseases and extreme weather conditions and are generally considered easier to grow.

The Santa Maria Autoflower is a true winner in terms of yield as well as having a rapid flowering time of 8 to 9 weeks. Santa Maria is the result of a crossing with Santa Marta, a renowned Brazilian strain with the Colombian Santa Maria. And adding some Ruderalis for good measure. Santa Maria can be grown indoors or outside. Although its resistance to damp, cold and mould makes it challenging in northern Europe, it can thrive if there is enough sunlight. We recommend growing Santa Maria indoors, where you will be amazed at the high-quality yield of this determined little autoflower.
With a fresh, flower and fruity aroma and taste, smoking Santa Maria auto is always a pleasure. It induces attentive, clear-headed and energetic highs that will provide you with intense feelings of euphoria.

How to make an autoflower grow even faster?
It isn’t really necessary to force the plants during their cultivation, but if you want weed as soon as possible, there are a few tips that you can put into play. However, it must be made clear that a plentiful harvest cannot be done in a short time, and that production must, therefore, be sacrificed if crop time is to be saved.
One method of accelerating the rate of cultivation is to plant the autoflowering seed in a small pot. When the roots do not have enough substrate, they start to flower to be able to finish the cycle with the nutrients that are available to them.
If you want to harvest a little sooner, you can apply certain products which advance maturation by a few days, both for autos and for standard cannabis strains.
