What Are Fast Flower Cannabis Seeds?
Unlike autoflowers, which bloom automatically after a certain time, Fast Granddaddy Purple offers control over flowering through the light cycle. This allows growers to shorten the growth phase for smaller plants or extend it for larger plants with higher yields. Thanks to a special cultivation method using the genetics of an autoflower variety, the flowering period is as short as an autoflower, but the plant waits to bloom until the days grow shorter. Fast flower cannabis seeds are perfect if you want quick results without sacrificing potential yield or control over the cultivation process.
Flavor and Effects
Fast Granddaddy Purple offers a flavor experience you won’t soon forget. Sweet grapes and ripe berries merge into a rich and refined taste. The effects start with a euphoric high that transitions into deep relaxation. Perfect for ending the day or promoting a good night's sleep.
Growth and Yield
This strain remains compact, with a height of 150-200 cm. Indoors, it delivers up to 550 grams/m², and outdoors, under ideal conditions, up to 1000 grams per plant. The purple buds are dense and resin-rich, emitting an intense aroma. It is easy to grow, even for beginners, and thrives indoors, outdoors, and in greenhouses.
Growing Tips from Dutch-Headshop
Fast Granddaddy Purple grows best in a sunny environment. Use techniques like Scrog or LST to maximize its yield. Ensure sufficient ventilation to prevent mold, and provide extra phosphorus and potassium during the flowering phase for more intense buds. For purple buds when growing indoors, systematically lower nighttime temperatures during flowering. Reduce the temperature by 2 degrees each week, which will replace the green chlorophyll with the deep purple hues of anthocyanins. This will also make your cannabis taste sweeter. The longer you let it flower using this process, the more intense the coloration. However, be careful not to deplete the trichomes completely. This fast flower will ripen earlier for harvest. Look for milky white to amber trichomes when growing Fast Granddaddy Purple.
