Fast Grandaddy Purple Feminized – Cannabis Bulk Seeds

Grandaddy Purple Fast Feminized – Cannabis Bulk Seeds

Grandaddy Purple Fast feminized is a fast-flowering version of the famous cross between Purple Urkle and Big Bud, plus a third secret ingredient.

Biologically, this strain was selected in our laboratories to reduce maturation times without losing the characteristic purple color and compact structure typical of indica-dominant strains. Unlike the standard version, the “Fast” version allows for early harvest by approximately 10-14 days, a crucial advantage for growing in areas with early autumns.

Morphology and Flowering Speed

Indoors, this plant completes flowering in just 45-55 days, producing dense, resin-saturated buds. The structure remains compact, with very short internodes that require thorough defoliation to allow light to penetrate.

Outdoors, harvest takes place between early and mid-September, avoiding autumn rains. The yield is massive for a fast strain, averaging 450-500g/m² under controlled conditions.

Terpene and Anthocyanin Profile

The aromatic profile of gdp fast is dominated by myrcene and linalool, which impart notes of ripe grapes and wild berries. According to Seedfinder’s technical data, Grandaddy Purple is known for its high concentration of anthocyanins, which turn dark purple already in the early stages of flowering if nighttime temperatures drop slightly.

This isn’t just an aesthetic trait; it indicates a complex synthesis of protective flavonoids.

Technical Data and Potency

With a THC level ranging between 22% and 25%, Grandaddy Purple Fast offers a deep and long-lasting physical effect. Biologically, the plant produces large calyxes and a generous amount of sticky resin, ideal for extractions.

The stability of our line ensures that each specimen expresses the original “purple” phenotype, maintaining the parasite resistance inherited from its Afghan ancestors.

More information

Grandaddy Purple Fast is the result of crossing Purple Urkle with Big Bud and a secret hybrid to give a fast finish.

She is a mostly Indica F1 strain suitable for indoor and outdoor growing that finishes quickly and produces very high levels of THC.

Grandaddy Purple Fast Feminized plants look really beautiful with assorted purple shades of the buds covered in a frosty white resin coating. The addition of Big Bud serves to increase its yield potential. Indoor plants will be ready after 7 weeks of flowering, sometimes a little faster, with yields between 350 – 400 gr / m2.

Outdoors, where plants are ready for cutting in late September, yields can be quite impressive. Mold resistance is good, despite its dense buds, helping in marginal growth zones. Power requirements are moderate, so don’t go overboard with things indoors or out.

Grandaddy Purple has an inviting aroma and taste; grapes and berries abound on the palate. THC production varies between 23-28%, giving a wonderful fusion of brain-stimulating yet physically relaxing effects. Get ready to float while securely attached to the sofa.
