Yes! While the 1:1 mixes are great to start, simple multi-ingredient recipes using only the cheap, initial Gas Mart items can be very profitable in the Schedule 1 Early Game. One specific recipe mentioned combines OG Kush with Banana, then Cuke, then another Banana (OG + Banana + Cuke + Banana). This mix reportedly costs only $6 in ingredients (plus the base OG Kush) but can sell for around $80. Experimenting with combinations of Cuke, Banana, Paracetamol, and Donut is encouraged once you're comfortable with the Mixing Station, as you might discover your own Best Weed Mix variation for the Early Game.
