The Tahoe OG will place you like hell. Bubba Kush is probably the best-known Kush variety, not called OG Kush. The Fire OG crosses the OG Kush with an SFV OG Kush variety. While the standard genetics you can expect from the OG Kush strain is 25% Sativa and 75% Indica, today there are many hybrid strains that tip the scales in both directions tremendously.
For the record, OG Kush responds well to hydroponics, although you'll need some experience growing marijuana to get the best out of this strain.
