About Speed
Speed lives up to its name: Sweet Seeds built this 60/40 hybrid from Critical Mass and Speed Devil #2 Auto genetics, and it finishes flowering in just six weeks flat. That kind of turnaround is rare outside the autoflower world, and it comes packaged in an easy-to-grow plant that tops out at a compact 60 to 90 centimeters, making it a fit for tight tents or discreet setups. Indoor yields land between 425 and 475 grams per square meter, respectable numbers for such a short cycle. Potency lands between 16.9 and 20.4 percent THC, giving growers real strength without asking them to wait two months for it. For anyone prioritizing speed and simplicity over a long, involved grow, this cross delivers exactly that.
