seedlings should be watered and have wet soil for the most part but let them dry out so water a little every day.

add some nutrients but little beacuse plants need to get used to it. (ie: put less than you think)

also when you transplant to the earth give it professional soil that you buy in a store. use a potting mix or go with one w/o fertilizer and add your own: organic or chemical. mix it with a little native dirt that ur growin in.

I suggest you keep a close eye on them at your place for the first month befor putting it in the place wherever ur growing. transplant when you see a full root system forming in the cup you are starting them off with. also before you put it in the final place, cut slits into the roots to promote more root growth.

The only time you will know what gender is when they go to a 12/12 light cycle. U r gonna have to wait till the end of the grow season.
