F1 Fast Version® strains are 100% photoperiod-dependent versions featuring ultra-fast flowering of some of the most appreciated genetics from the Sweet Seeds® genetic collection. These new genetics are F1 hybrids. When grown indoors, these marihuana plants are ready to harvest just 6 or 7 weeks after the photoperiod switch to 12 hours of light and 12 hours of darkness. When grown outdoors, the plants anticipate harvest for about 1 to 2 weeks regarding to their original versions.
Due to their fast flowering, these strains are very appropriate for growing in humid and rainy zones, in high mountains or regions with cold winters. In these areas that are especially sensitive to fungus attacks, these strains are very adequate because they manage to anticipate harvest to the season when the most virulent botrytis (grey mold) attacks, decimating the buds of the plants that feature longer flowering periods.
