Shalom Meyer,
My Hebrew name is Meyer!
you have one plant, yes.
The plant has two stages, Vegatative and Flowering.
is the plant in soil?
what age is The Plant?
do you have nutrients?
you have a tent, yes!
what type of Light are you using?
What light schedule are you using?
(Keeping light schedule 12/12 if you want slightly quicker results)
With lights set to 12 on 12 off as soon as the plant is mature it will show its sex.
female = is good, Keep it
male = no good, kill it
Good Luck!
