indoor, greenhouse Powerplant (mostly Sativa) was developed by us in 1997 from new South African genetics. This strain has been inbred only, never hybridised. Very rich in THC. It is a strain with an enormous grow potential. Indoor as well as in a greenhouse the plants have an enormous yield. Indoors flowering starts already one week after turning back the lightcycle to 12 hours. Outdoor, flowering starts late, but the plants ripen very fast. This variety is very uniform. Strong "up high", very soft smoke. THC: 15% flowering period: 8 weeks harvest time outdoor: 2nd week Oct.
