Divine Seeds Fractal grow on balcony

All the ladies are doing well. During the warm and sunny weekend they spent some time outside, but as usually the wheather changed and they are inside now and under a 10W LED Growing lamp especially for the young plants. No nutrients are currently used. Day11: Fractal is by far the most growing seed, next leaves are appearing. I put the plants a bit nearer to the lamps, don't want to become the stems too long. Temperature outside is 14°C, too cold, so they must stay inside. Day13: The weather was fine outside.
