Auto flowering strains pass directly from the seedling to the flowering stage, thus altogether doing away with the vegetative growth stage. Basically, when the plant is grown it sprouts, grows a set of leaves, then immediately and automatically begins flowering. What this means is that it is the quickest, most compact, and most easily concealed plant. These plants do not need a change in light cycle to induce flowering, they will just start flowering automatically anywhere between 2 and 3 weeks into their life and will then be all finished within another 5 or 8 weeks.
