Formerly "Cannabis ruderalis", now re-classified as Cannabis sativa. These short stocky autoflowering cannabis plants come from northerly latitudes and begin to flower in relation to an oft-quick reached sexual maturation, regardless of photoperiodism influences.
If you're looking to get into breeding autos, these are great adaptable genetics to work with. Easily pick a male auto from these regular seeds and pollinate a favorite female clone. Or for more advanced growers, choose a standout female auto from this seed batch while flowering a reversed clone your favorite female genetic to make feminized seeds.
Breeding autos and photos together brings progeny forward that will exhibit faster flowering times in photoperiodism expressions and stronger, more flavourful expressions of autoflowering expressions.
By selecting and further breeding plants which exhibit autoflowering and other desireable traits, you can create new autoflowering cannabis strains.
Note: Highly resilient to cold weather. I breed mostly indoors with reg. seed and when males show up, I toss them outdoors into the Canadian winter to expand illuminated canopy space. While outside, the rain, wind, cold, pests and mold pressures help select strong males (weak genetics mold, yellow, stop growing, or die). After a couple weeks of rough conditions and extremely slowed growth (delayed flowering; a type of stasis to keep males in for longer pollination windows), the hardiest males may be brought back inside for use in selective pollination projects in tents. (Mostly crossing photo keeper cuts to vigorous and hardy autos.)
