from what i have learned about the Iranian Short Season is that it will veg (and CLONE) with 24 hour light, but any dark periods and it will begin to bloom.
outdoor from seed it will grow to around 3-5 feet (just what i have read) i know that Sodalite has a grow journal around somewhere from seed outdoor.
clones will flower at whatever height they are are put outside, meaning veg them indoors then plant them outside early/midsummer and they will bloom immediately.
i will be ordering these shortly.
