my first grow

ok so i have 5 plants growing in my garage in my truck bed i have 2 florescent lights on em and tin foil around them to reflect all the light back in right now what i am growing is just some seeds i got from schwagg but i'm hoping that if i seperate the male and females at the right time and keep the right ph and nutrients that ill maybe be able to turn it into some decent chron i was just wondering if anybody had any input on the best way to make it produce some good chron also what some good ways are to boost the harvest thanks for any help
