First grow help

I have a wood box 3x4x4 feet. it will be in a shed with no heat and it is the middle of december now, my seeds have been germinating for a week so i think its time to plant them, i bought some good potting soil and i am going to use jiffy pots then 3 gallon buckets. what wattage and amount of cfls am i going to need to provide enought light and heat for the plants. also what watering and light cycles should i start with. do i need nutrient is so what kind? also will opening up the box to water be enough to ventilate or will i need to cut a hole with a fan?

thanks

Depends how cold it gets outside where you are. It was 14f here last night im inside with the heat on at 65f. My closet gets up to 80 and drops to about 70 im guessing at night. I have 12 cfls split between the flower and veg rooms. When i started i didnt have that much light and it was around 60f and most of my stems where purple, which meant it was too cold. If u can get it about 65f u should be fine but depends how cold it gets outside.

i have 4 plants so many light bulbs and of what wattage and lumen am i going to need?
