they have a website. google centennial seeds.

here's what they say about the strain (which I'd like to give a shot!)

(Hawaiian Heirloom Variety)
This seed stock came to us as a gift from the beautiful Waipi'o Valley (pronounced ??why-pee-oh?) on the North shore of the big island of Hawaii, USA.

Waipi'o Hapa is remarkably vigorous, finishes fast and produces heavy yields every time. The fragrance is of fresh lime and hibiscus flowers.

The effects are undeniably Sativa, both stimulating and strong. We recommend Waipi'o Hapa as appropriate for:

pain, energy, mood elevation, appetite suppression
