Not an actual strain
Green Poison F1 Fast Version is Sweet Seeds' feminized, photoperiod-dependent version of the classic Green Poison featuring ultra-fast flowering — an F1 hybrid resulting from crossing the elite clone of the appreciated Green Poison with a selected 3rd Generation autoflowering genetic line of Green Poison Auto. The strain is ready to harvest with thick buds covered in abundant aromatic resin just 6 weeks after the flowering photoperiod begins, which is genuinely exceptional for a photoperiod strain. Plants display the appearance of Indica-Sativa hybrids with exceptionally vigorous growth, very fast flowering, and large flower production. The taste and aroma are exquisite, with a sweet intense hint of fruit. This strain is remarkably resistant to mold in outdoor grows — the fast flowering lets it beat the botrytis season that typically attacks traditional outdoor photoperiod strains, making it particularly valuable for humid climates where slower strains would fail.
Plants feature 70% Indica and 30% Sativa genetics, developing medium-to-tall architecture with vigorous growth and sturdy side branches that support large heavy resin-packed buds. The F1 breeding approach combined the elite Green Poison clone as the base genetic with a specially selected Green Poison Auto line, producing a photoperiod-dependent strain with ultra-fast flowering that doesn't lose the aromatic essence or productivity of the original parent. Indoor yields land at 500-600 g/m² under optimal growing parameters, and outdoor plants with good soil and adequate nutrition produce 500-700 g per plant.
The effect profile delivers a predominantly physical and relaxing experience accompanied by a light creative spark that pleasantly stimulates the mind. THC content ranges 15-20% with approximately 0.5% CBD. The relaxing property produces pleasant physical effect promoting body well-being; the creativity component offers gentle mental boost stimulating inspiration; and after moments of happiness and relaxation, it provides a notable boost in appetite. Flavor delivers an intense sweet and fruity profile with spicy arugula undertones and a Skunk background that intensifies and rounds out the organoleptic experience. The strain has won 2 cups so far, with growth continuing as more competitions recognize the F1 Fast Version's exceptional speed-plus-quality combination. Recommended for collectors of photoperiod seeds with ultra-fast flowering, high yields, potent relaxing effects, and intense sweet-fruity flavor with spicy undertones.
For commercial growers and home cultivators wanting fast turnaround without sacrificing quality, Green Poison F1 Fast Version occupies an unusual niche: the 6-week flowering window is genuinely exceptional for any photoperiod strain, and the F1 breeding approach produces consistent pack-wide expression rather than the phenotypic lottery of traditional polyhybrid crosses. The mold-resistance property is particularly valuable in humid climates and wet autumns where standard photoperiod strains routinely fail — Green Poison F1 Fast Version's ability to finish ahead of botrytis season gives outdoor growers in challenging regions a reliable option for premium-quality flower.
Between the 6-week flowering, the heritage Green Poison genetic foundation, the high yields, and the relaxing creative effect profile, Green Poison F1 Fast Version earns its place in the Sweet Seeds Fast Version catalog as a flagship modern release. For growers running perpetual rotations or tight commercial schedules, the combination of speed, yield, and quality delivered in a stable F1 format makes it one of the most practical premium-tier strains in the contemporary Sweet Seeds lineup.
