Not an actual strain
Black Muffin F1 Fast Version is Sweet Seeds' ultra-fast flowering photoperiod-dependent feminized strain that develops red flowers — a first filial generation F1 cross between a photoperiod-dependent elite clone of Red Hot Cookies and the select autoflowering strain Black Lemon Auto. The strain has vigorous hybrid character and grows long side branches with thick, compact buds soaked in aromatic resin. Buds turn dark purple during flowering, emitting a thick potent sweet-and-sour aroma with fresh citrus tones of lemons and mandarins plus a tart undertone of red berries. The effect is intense yet balanced — relaxing and happy, stimulating conversation and imagination simultaneously.
Plants feature 60% Indica and 40% Sativa genetics, developing sturdy architecture with long side branches holding thick compact buds. In approximately 60% of plants, flowers take on reddish or deep purple tones during flowering — a high rate of color expression for a photoperiod-dependent strain. The breeding approach combined the Red Hot Cookies elite clone with a selected autoflowering genetic line of Black Lemon Auto, preserving the best attributes of both parental lines: red flowers, ultra-fast flowering, complex aromas, and balanced effect. Indoor yields come in at 500-600 g/m² under optimal parameters, and outdoor plants with good soil and adequate nutrition produce 400-600 g per plant.
The effect profile combines creativity that promotes inspiration, free thinking, and artistic connection ideal for enjoying creative activities, stimulating character delivering positive energizing high that encourages conversation and social enjoyment without being overwhelming, and relaxing quality providing pleasant sense of physical and mental well-being perfect for unwinding without losing clarity. THC content ranges 17-25% with approximately 0.1% CBD. The synergy between the cannabinoid profile and distinctive terpenes results in an intense well-rounded high that begins with stimulating effect encouraging dialogue and creativity, then gently transitions into soothing body relaxation. Excellent choice for social gatherings, artistic projects, or simply enjoying the moment with a smile. Flavor delivers fresh citrus notes of lemon and mandarin, sweet-and-sour fruity undertones lingering on the palate for several minutes, and slightly acidic hints of red forest fruits. Released by Sweet Seeds in February 2024. Recommended for collectors of fast-flowering photoperiod genetics looking for red-flowered strains with high THC content and fruity citrusy aromas — perfect for those who enjoy intense flavors, balanced effects, and visually stunning plants.
Black Muffin F1 Fast Version was released by Sweet Seeds in February 2024 as one of the newest additions to the Fast Version catalog — Sweet Seeds is confident the outstanding quality will soon be recognized at various cannabis events, and growers interested in entering competitions have an opportunity to showcase it before the strain builds its full award history. The red/purple flower expression in approximately 60% of plants combined with the ultra-fast flowering time makes it a genuinely distinctive modern release.
For growers interested in red-flowered cannabis specifically, Black Muffin F1 Fast Version is one of the cleaner options in the commercial market — the color expression rate is unusually high for a photoperiod-dependent strain, and the F1 breeding approach means pack-wide consistency rather than the unpredictable color development that polyhybrid crosses often produce. Combined with the balanced relaxing-stimulating effect profile and the fruity citrusy aromatic character, it represents a unique combination not readily available from other breeders.
