yeh 1st sprout in beer can

my 1st sprout apeared and is going mental it 1st poked its head out in morning and by ened ofday was 5 cm tall its proper leaves are coming in just want to no if put it into 12/12 will it tart flowering this is my ultra mini gro experiment and want to keep it as small as possible

I don't think it can start flowering until at least 2 or 3 weeks after sprouting, minimum. But I could be wrong...

Ive seen threads were people start their seeds on 12/12 lighting or a couple days after.
