Girl Scout Cookies autoflowering

Description

Superb flavour and potency with these tasty Cookies..

The Girl Scout Cookies (GSC) variety is bona-fide high-quality marijuana. It is without a doubt the best Californian strain of all time. Currently GSC has a large number of fans throughout the United States West Coast, and is going strong in Europe, Eastern Europe and Asia. FastBuds have managed to recreate an auto flower that does the original GSC justice. They've selected the two most popular phenotypes of the Original GSC and created an auto flower version of this spectacular plant. The result is an Indica-dominant hybrid (almost 60%), with Canadian Ruderalis and Sativa making up the difference. This plant presents a very undemanding crop, but like the art of baking cookies, take your time, Mother Nature can't produce such a deliciously minty, chocolaty product overnight!

Overall, Girl Scout Cookies stands out as one of the brightest and most exotic varieties in recent years, a true masterpiece! Would you like a cookie?

GSC auto. One of my favourite strains easy to grow veg time a little under 3 weeks fast to flower after veg , I started with 200 Watts cfl for the veg stage then switched to 250 watt hps for flower stage, from germination to harvest 85 days or 2 months 24 days to get the milky trichomes I like, this is a pretty plant to grow she looked beautiful the buds look a nice green colour, great sweet candy taste. Effects are strong with a long lasting high body and mind. Overall just fire taste great looking cured buds smells amazing.

Very small plants. Decent genetics but yield but only averaged around half an oz off every single plant by this breeder even different strains.
