skunk#1 was one of the first stabilized strains bred specifically for indoor cultivation.its 50%afghani which is pure indica,very dark,stumpy broad leafed plant,and also 25% thai and 25% mexican..which are both sativas....usually a much taller,loose bud plant w narrow leaves..so it wasa hybrid( ive got some bad weed memory so this could well be wrong-please correct me if so..)
As the post above says,the gene pool of weed is now so mixed that its hard to lable a strain..there's also rudderails..as well as sativa and indica..
Even seeds from seed banks are rarely a stable strain..it takes alot of cycles and elimination process to stabilize,so its alot of bull shit..
If people out there get the chance to start a personal use indoor garden , i highly recommend it...its agood hobby andvery satisfying to smoke your own pride and joy...
