4 weeks old......

I have been growin my blueberry seed for 4 weeks and its like 8inches tall. with some leaves but how long do i leave the light on for 24hours. and i water it only in the morning with bottled water. what else do i do? my friend told me to spray a mist of water on the leaves is that good. all the leaves are still green. HELP please

what lights are you using? and how close are they. and what size pot

These are pictures of my plant..........
i have it in a bucket. with a plant light thats got a green tint but i have been reading i should be using a blueish tone. please tell me what to do because i started this in the begining of december. and i really want it to work so bad. Is it tru if i use blueberry juice with water it will have more blueberry taste, or if i add food coloring it will change colors. THANKS

food coloring will change the color but leave u with a horrible taste

Dang that plant is linky
