DP Blueberry Q's

[Broom]

soo i was wondering if anyone knew the best type pot/pots (if i need them for different periods of growth) and soil/soil recipe to use for my first grow ever, DP Blueberry. i'm growing it in a small drywall inlet with a sealed door, a crawlspace in my closet basically. i have a 250w HPS flood lamp that im will be using with a heater to regulate temperature. what would an optimal temperature be for a grow like this? also, how often should i water it and keep the light on? these are all questions i need answered, i MUST grow this with 100% effort and yield!

p.s. i know that violet colored light is the most effecient for growing (learned that in bio), so would it be wise to use a violet light at the begining stages of growth, then switch to white light later on?

thanks!!
