waiting for your advices

hey everyone im a newbie about this self-growing thing. i started growing just 2 weeks ago and today, i realised that i forgot something important. i only have one plant under continious light. i forgot about the plant being male or female. (dumb eh?) so assuming i'll have a killer female plant, i've been raising my only plant for 2 weeks.

today, realising i have really low chances of that plant being female, i'm thinking of starting all over again. ( i have some germinating seeds somewhere else.) and i wanted to hear your advices.

i'm workin inside a closet with a space of 22x20 inches

i have some pots

i have a lamp over 1500 lumens

some fertilizers and epsom salt

and lots of soil.

what should i do? should i start all over or should i keep being busy with my only plant? i i should start all over again, how many plants should i start with?

waiting for your advices

i also forgot to add something. i think when i was transplanting the plant, the stem broke from a close point to the root. should i take the risk and continue?

and btw how many plants do you think i should start with if i would?

should i use small pots or large ones?

my current pot is real big, takes almost all the space i have.
