Growing Nero Toscana Kale in Kratky Hydroponics – Update: Week 3

Nero Toscana Kale Grown In Kratky Container, Week 3

This week we saw the kale’s leaves turning a beautiful silvery shade. The picture below hasn’t been photo-edited. They color is fairly accurate to what I see myself.

The largest leaves are about the size of my palm, and I expect that they will probably get much larger.

Lets compare that color to the previous week leaves, which had the bright green of most seedlings:

The kale still looks quite small, especially compared to some of my other hydroponic plants such as the Swiss Chard. That’s okay; kale is slow growing; it takes 70-80 days for it to reach full maturity. It’s only 25% through its life cycle, so its barely even a teenager.

If you look closely at the base of each branch you can see a number of new leaves and branches beginning to emerge. The Cotyledons, or first leaves, are just beginning to droop, so they will probably die and fall off in the coming week.
