Sweet Seeds Autoflowering Seeds — Catalog at Edabea

Sweet Seeds is a Spanish seed bank founded in Valencia that has developed one of the most documented catalogs of autoflowering seeds in the specialized market. Their autoflowering varieties are identified by three own traits: the generation numbering (3rd, 5th, 6th, 7th, 8th generation) indicating the level of development and stabilization achieved, the XL line of larger versions obtained through recurrent selection, and the line of red-flowering varieties — a visually distinctive phenotype that turns the buds into dark purple and red tones during maturation. At Edabea, you will find more than 30 autoflowering references from Sweet Seeds. To also view their photoperiod feminized varieties, access the feminized catalog of Sweet Seeds on Edabea. If you are looking for other autoflowering banks, you can return to the autoflowering category or to the general seeds category.

The Sweet Seeds Generation System

Sweet Seeds documents the generation of development for each autoflowering variety — a piece of information that indicates the number of selection and genetic stabilization cycles the variety has gone through since the original cross. The higher the generation number, the greater the stability of the phenotype and the greater the homogeneity among plants.

The bank's first autoflowering seeds were of 2nd generation; the most recent varieties in the catalog have reached 8th generation. The Mimosa Bruce Banner XL Auto (8th gen) and the Orange Apricot Glue XL Auto (7th gen) represent the highest level of the current catalog. In contrast, the Cream Caramel Auto — described as "3rd generation autoflowering" — was one of the first stabilized autoflowering varieties of the bank, which explains why it remains in the catalog with that designation without a generation update: it is a well-established reference, not a new one in development.

XL Line — Larger Versions

Sweet Seeds has developed XL versions of several of its most popular autoflowering varieties, obtained through a recurrent selection program of larger individuals over multiple generations. The XL varieties produce plants with significantly greater height than the standard version — the Green Poison XL Auto produces plants that are 25% taller than the original Green Poison Auto, according to the bank's sheet. The XL line includes references such as Big Devil XL Auto, Jack 47 XL Auto, Cream Mandarine XL Auto, Green Poison XL Auto, Red Gorilla Girl XL Auto, Sweet Mandarine Zkittlez XL Auto, Mimosa Bruce Banner XL Auto, Orange Apricot Glue XL Auto, Diablo Rojo XL Auto, and Jet Fuel Mandarine XL Auto.

Red Flower Line — Differentiating Visual Phenotype

Sweet Seeds has developed a line of autoflowering varieties with a unique visual phenotype in the seed market: the buds take on intense purple, almost black, or reddish tones during maturity. This phenotype results from the accumulation of anthocyanins — plant pigments present in many plants — in the floral tissues, a process that intensifies with the lower temperatures at the end of the cycle. The red-flowering varieties in the catalog include the Dark Devil Auto, the Red Poison Auto, the Bloody Skunk Auto, the Diablo Rojo XL Auto, the Red Mimosa XL Auto, and the Red Gorilla Girl XL Auto.

The + Speed Auto — The Shortest Cycle in the Catalog

The + Speed Auto is the variety with the shortest cultivation cycle in Sweet Seeds' catalog: ready for harvest in 7 weeks from germination. This is the lower extreme in cycles of the bank's autoflowering catalog, compared to the standard cycle of 10–11 weeks for most varieties. With a faster cycle, there is less developmental time available for the plant — the stature and yield are proportionally more compact than in full-cycle varieties.

Legal Situation

The sale of cannabis seeds in collection format is legal in many European countries, although germination and cultivation are subject to each jurisdiction's regulations. It is the buyer's responsibility to verify the applicable legislation in their place of residence before germinating or cultivating. The seeds are sold exclusively as collection material.

Frequently Asked Questions about Sweet Seeds Autoflowering Seeds

What does the generation number mean in Sweet Seeds varieties?

The generation number indicates how many selection and genetic stabilization cycles the variety has gone through since the original cross. A 3rd generation has been selected and stabilized three times; an 8th generation, eight times. The higher the generation number, the greater the phenotypic stability — the plants are more homogeneous and cultivation behavior is more predictable. The most recent varieties in the catalog (8th gen like the Mimosa Bruce Banner XL Auto) represent the highest level of development currently achieved.

What is the difference between an XL variety and its standard version?

XL varieties are larger versions obtained through recurrent selection of larger individuals over multiple generations. It is not a cross with another genetic — it is the same variety selected to produce significantly taller plants. The Green Poison XL Auto, for example, produces plants that are 25% taller than the standard Green Poison Auto. XL varieties are suitable for outdoor crops where vertical space is not a limitation, or indoors with more height available.

Why are the buds of red-flowering varieties dark in color?

The reddish or dark purple color of the buds in Sweet Seeds' red-flowering varieties is due to the accumulation of anthocyanins — plant pigments that activate in response to lower temperatures during maturation. Anthocyanins are present in many plants and are responsible for red, purple, and blue colors in fruits, flowers, and leaves. In cannabis, this phenotype is genetic — plants predisposed to produce anthocyanins express it especially with temperature drops at the end of the cycle.

How many harvests per year can be made outdoors with Sweet Seeds autoflowering varieties?

It depends on the climate and the variety. With the standard cycle of 10–11 weeks, in temperate southern European climates, it is possible to obtain two or three harvests per season. With the + Speed Auto (7 weeks from germination), the shortest cycle in the catalog, the margin for additional rounds is greater. The first planting can be done when minimum temperatures consistently exceed 10°C, usually from April to May; the last harvest should be collected before the first frost.

What is the Sweet Mix Auto and what varieties can it contain?

The Sweet Mix Auto is a pack of 10 randomly chosen autoflowering seeds from all varieties in the Sweet Seeds catalog, including references like Cream Mandarine and red/purple flower varieties. The selection varies with each batch — it is not possible to know exactly which varieties will be included in each pack. This is the option to compare different genetics from the bank in a single purchase.
