BSF Seeds is a Spanish seedbank that works clone-only US genetics (GG#4, Cookies Forum, Sour Dubb) into stabilised feminised and autoflowering seeds you can actually grow at home. The catalogue splits into three clear groups: feminised photoperiod, standard autoflowers, and XXL autos that rival photoperiod yields. Most packs are 4 seeds; mixed packs run 12.
Not every BSF strain is for every grower. If you want to shop smart, pick by what your space and schedule can handle — not by THC percentage alone.
| Type | Cycle | Yield range | Good for |
|---|---|---|---|
| Feminised photoperiod | 7–10 weeks flower | 400–700 g/m² | Growers with a timer and a veg stage — GG#4, Super Lemon Haze, Rainbows, Double Cookies |
| Standard autoflower | 60–75 days seed-to-harvest | 400–500 g/m² | First-time buyers, balcony growers, anyone wanting a quick turn — GG#4 Auto, Red Critical Auto |
| XXL autoflower | 75–80 days seed-to-harvest | up to 600 g/m² | Auto growers chasing photoperiod-size harvests — Moby-D XXL, Tangie XXL, Orange Blossom XXL, Lebron Haze XXL |
| Fast-version photoperiod | 40–42 days flower | 400–500 g/m² | Short-season outdoor, guerrilla grows — OBG Kush |
| Mixed packs (12 seeds) | varies | varies | Buyers who want variety in one order — All Stars USA Automix, Psycho XXL Auto MIX, Gorilla Family Mix, Dream Team Mix, High Voltage Mix, Dealer Deal XXL Automix |
Read the table by cycle length first, yield second. A 65-day auto in an 80x80 tent will almost always beat a photoperiod you rush through veg to save time.
New to growing? Order a standard autoflower. GG#4 Auto or Red Critical Auto will get you from seed to jar in about 65 days without needing to mess with light cycles. Buy one 4-pack, set up an 80x80 tent, and learn on forgiving genetics before you spend money on clones or photoperiods.
If you've run a few cycles and want bigger harvests from the same tent, shop the XXL auto line. Moby-D XXL Auto and Orange Blossom XXL are where BSF's third-generation ruderalis work actually shines — same easy schedule as a normal auto, roughly twice the yield. Photoperiod growers who want fast turns should grab OBG Kush; 40–42 day flower is genuinely unusual and holds yield.
Chasing potency or extract material? Buy GG#4 feminised, Double Cookies, Nicole Punch, Choco Cream or Nerdz — all pushing 27–30% THC with the trichome coverage to back it up. Star Power (BSF Seeds x Moon Rock) is the collab pick if you want candy-terp Zkittlez crosses. When in doubt, start with GG#4 Auto — it's the single most forgiving strain in the catalogue and a fair showcase of what BSF does well.
BSF Seeds works clone-only US genetics — GG#4, Cookies Forum, Sour Dubb, Do-Si-Dos — into stabilised feminised and autoflowering seed. The XXL autoflower line is the standout: third-generation ruderalis crosses that hold 500–600 g/m² yields, which most auto breeders still can't match.
Order GG#4 Auto or Red Critical Auto. Both are autoflowering, finish in 60–65 days, and don't need a light-cycle switch. They handle feeding mistakes better than photoperiod strains and give you a realistic first harvest without tying up a tent for four months.
Most BSF feminised and autoflower packs contain 4 seeds. The mixed collections — All Stars USA Automix, Psycho XXL Auto MIX, Gorilla Family Mix, Dream Team Mix, High Voltage Mix and Dealer Deal XXL Automix — contain 12 seeds split across 4 strains. Star Power comes as a 10-pack.
Yes, if you give them space and nutrients. A Moby-D XXL Auto or Tangie XXL Auto in an 11–15L pot will out-yield a standard auto by 30–50%. In a 5L pot on minimal feeding, you won't see the difference — the genetics need room to express the XXL part.
OBG Kush at 40–42 days flowering is the fastest photoperiod in the catalogue. For autos, Double Cookies Auto and GG#4 Auto finish around 8–9 weeks from seed. Green Tiger is the fastest feminised photoperiod at roughly 6 weeks from flip to chop.
