Black Muffin F1 Fast Version by Sweet Seeds
Black Muffin F1 Fast Version brings the Red Family direction into a very early photoperiod format. It combines Red Hot Cookies with Black Lemon Auto, and that gives the cultivar two defining traits at once: a compressed flowering window and a dark, color driven flower finish that develops into deep purple tones.
The plant builds with a strong hybrid frame, longer lateral branches, and enough structural substance to carry its later flower weight cleanly. The canopy does not feel squat or crowded. It spreads with purpose and keeps a well branched outline. Dense, compact buds form across that frame and start pushing resin early, which gives the upper plant body weight fairly quickly.
Sweet Seeds lists the cultivar as an F1 Fast Version with ultra fast flowering. The breeder gives indoor production at around 500 to 600 g per m² and outdoor production at roughly 400 to 600 g per plant. THC is listed at about 17 to 25 percent, with very low CBD. This is not a small quick finish line, but an early, fairly substantial fast flowering hybrid with real flower mass.
The aroma opens on a sweet and sour fruit layer, then moves into lemon and mandarin before a sharper red berry note follows behind. That sequence keeps the cultivar from collapsing into a simple candy profile. The citrus side keeps the scent bright and fresh, while the berry edge adds depth and a slightly darker trailing note.
The main shifts inside the line usually appear less in the overall direction and more in emphasis. Some plants push the citrus edge harder, while others let the berry side come through more clearly. The dark coloration can also arrive earlier or later in flower. Even so, the finished picture stays consistent: a fast flowering, color heavy hybrid with long side branching and a clearly sweet sour citrus fruit core.
