I had the same thing.. I grew 2 from seed and got 2 phenos. One was average at best and the other like you mentioned.. Shitty airy buds that i too waited 14 weeks for.Their Super Silver Haze was bullcrap for me. Grew huge. But it flowered for 14 weeks without ever filling out a calyx. Huge airy buds of worthless bud. Even the hash we ended up making with it was super low in yield and worthless as far as quality was concerned.
