KUSHINDICASEEDS

Abbreviations such as F1 and F2 on a seed pack describe how far a cross has been developed. With indica hybrid seeds, an F1 label means the first generation from two distinct parent lines, which usually gives vigorous and fairly uniform plants. F2 seeds, made by crossing F1 siblings, show much wider variation and are favoured by growers hunting for unusual individuals. Polyhybrids, produced from parents that are themselves hybrids, are the least predictable of all.
