GMO AutoCotton Candy
Potent and resistant variety displaying plenty of hybrid vigour.
Cotton GMO Auto is a cross of GMO Auto and Cotton Candy strains. This is a highly vigorous and mould-resistant strain that also boasts good resistance to cold and arid conditions. A very potent auto-flowering variety. Atlas Seed claims between 99.9% - 99.96% female plants from these auto-flowering seeds.
Cotton GMO Auto produces purple buds on a limited number of side-branches as well as the central stem and these buds are liberally coated in resin. The total grow-cycle is 75 days from seed all the way through to harvest.
Both scent and flavour are very sweet and sugary, from the Cotton Candy side, with pronounced fuel and fruit notes. Very high THC content lies between 20 - 28%.
