Seedsman WW all the way !!
Its an amazing high, great yield, easy to grow in dirt.
Hydro is a bit trickier as it REALLY likes 5.8 - 6.0 with very little fluctuation. I have 12 plants at 3 weeks flowering, 3 at 8 weeks flowering,
and 18 clones just went into rockwool cubes. I Veg for 4 weeks and end up with 5-6 foot plants by harvest.
It's also great watch your friends take hits off your volcano with this stuff - esp if they usually smoke Mexican crap in a blunt.
FYI - Butane Hash Oil made from this stuff is scary
