Growing Nero Toscana Kale in Kratky Hydroponics – Update: Week 1

Kale Grown In Kratky Container, Week 1

It’s been one week since I planted my kale seeds in my Kratky hydroponic container, and its time to see how they have grown! The variety is Nero Toscana.

Please excuse the dusty lid; whilst my plants are growing inside, we still get quite a lot of dust from dust storms, and just general air. I also noticed that my paint hadn’t fully cured and was slightly sticky, thus catching all those little dust particles.

4 out of 5 of my Nero Toscana kale plants sprouted, and have grown enough to remove the little grow dome (salvaged from some used Aerogarden Bounty pods).

One net cup did not sprout anything at all, even though I planted three seeds in each cup. In itself I would consider this just bad luck, but in the Swiss Chard bucket beside this one the same outer cup didn’t grow there either.

The rock wool medium is wet, so the seed should be getting enough moisture to germinate. Perhaps there is too little light reaching these outer cups? I have switched the outer cup with an inner cup in the hopes that it gets the light needed for a slightly later blooming, but so far nothing.

Do you have any idea why just one cup might not germinate? Please share your ideas in the comments below.
