first, why did you not germinate the seed first?
second,...

ok, let me restart,

i have only seen one article about being able to distiguish the sex of a seed. and you said "reggies", so i have to assume it is not a purchased feminized seed. so don't count on the female part.

first, NEVER start a plant in straight mg soil, it's just too potent. before you plant, you should germinate the seed.

what kind of light are you using (bulb/wattage/spectrum)?

check out FAQ's, youll learn ALMOST everything you need to know, and here's a link to a great gro guide...

do some research, and then you'll better be able to ask for what you need to have/know.

hope this helps,

love, brooke
