On the first day of the second week everything looks very good. The leaves have a rich green and develop quite fast.
Day 9: I gave the small ones about 100ml water per seedling.
Day 11: The next pair of leaves is in the early stages.
Day 14: On the last day of the second week you can see very well that the plants 1&3 are developing a bit faster than 2&4. Let's see how the next week goes on. Keep growing little cookies gelato.
