any one heard of green crack and where can i get it
Green Crack is a famous "clone only" strain, meaning that almost everyone growing it is doing so from passed around clones.
If you've never tried this one, the strain is known for both high potency (typically about 18-20% THC), a racy sativa-like "up" high, and a characteristic fruity mango-like smell. Its also fairly friendly to growers having a nice branchy pattern and a relatively short flowering time of only 7-8 weeks.
If you're in a medical state, you may be able to locate a clone.
If you can't find a clone, new breeder Sickmeds s-eeds has a version out in ceed form. This version comes from a Green Crack clone chemically forced to make male flowers, then self-fertilized to create feminized S1 ceeds.
Like most S1s, these ceeds will put out a number of phenotypes, some a little more sativa-like, and some a little more indica-like, and a few nearly identical to the parent clone only strain. In any case, reportedly all of the phenos have the characteristic mango-like scent, and all should finish relatively quickly. If you can't get your hands on the clone, this is your best bet.
I'm actually going to be starting a grow journal on this one relatively soon; probably in the next 2 weeks.
