Tell me its enough!!!!

I am currently in the tenth day of growing my 7 White Russian plants. My last grow I grew 3 plants but all three ended up being males. I decided that I was going to for sure get some females if I planted more plants. I decided on the #7...lol. I am doing a closet grow that is about 3feet wide by 5 feet long. I have plenty of overhead clearance. Im growing them under a 400watt HPS. Do you think that I need to add more light or should this be ok?

That 400 watt light should be enough.

the 400 should produce you some nice bud. what kind of medium are you using? hope for 3 nice fems. LST "low stress training" might do you some justice when it comes to your yeild. if you do use LST make sure its done while your plants are in veg. you'll have some nice bushes if done correctly along with filling in your space a little better. peace.
