Blueberry Auto - From Top Tao Seeds

I have germinated 5 seeds in a cup of water placed in a dark place. They all germinated within 36 hours. Transplanted them directly into the 7 liters containers. Day 1 - 6 All The Blueberry Auto's are showing a bit of stretching due to space between light and the sprouts and also from starting directly in 7 liters containers. I will be adding a bit of extra soil on top of each container to help stabilize the stems. I water with about 250ml water for each container every day, as the top of the soil is dried out next day. Day 7 About 250ml water each container every day, has resulted in nice looking Blueberry Auto sprouts with broad shaped leaves. (See Photos) I will be watering every second day but with 300ml from now on, to add wetness deeper in the containers so the roots shoot deeper down to reach the water and develop a bigger root system.
