Second time watering

It's March 27th and I will be watering once the boiled and microwaved water cool down. Since I planted this round of onions I have noticed similar verticle growth in all four pots. The boiled water and microwaved water pots started growing a new leaf! The plant that was left over from the last experiment has also started growing a new leaf, its color is looking healthier and it appears to have more water in its leaves now too.

The other two pots look just as healthy, but no new leaves are in sight just yet.

Note the two new leaves in the microwaved water pot (right) and the new leaf on the boiled water pot (left).
