Sensi's Hashplant
Rez said some of the Sensi Hindu Kush he grew were ready in like 42 days.
c99 has been the fastest plant I've grown. Most plants are ready around 50 days, give or take 5 days. I'm growing Apollo 11 for the first time right now and it's said to have the same time as c99.
c99 is available from Actual Seeds.
Plants that flower fast however usually require a lengthy veg. period to produce nice yields.
