About 2 weeks after planting the seeds, they already have some leaves, and you can see white roots showing through the jiffy as in the image above. This seedling needs more space for its roots to grow: it is time to transplant them to the growing pot. If you wait too long, you are constraining the plants potential for growth. The plants I did not choose for transplanting stayed small; while their lucky sisters in the arlite thrived. I’ll explain this: you usually plant more seeds than you need, just in case some of the seeds do not sprout. In my case I planted six seeds but only planned to grow two plants. Guess what, even if you have seen them growing for just a few days you become a bit attached to them. I did not have the guts to just throw them in the bin. Instead I kept them alive in the jiffies, watering them with the same solution I was using for the real culture, while I searched for an adoptive parent. Two or three weeks later I found a new home for them 😀
You need to fill the deposit with a not too concentrated nutrient mix, because plants need less food when they are this small. I will be adding more fertilizers as the plants grow. I prepared the nutrient mix with the help of a Nanny and the App: it has a very useful visual tool for mixing a perfect nutrient solution. You do not need to know which pH and conductivity values are good for cherry tomatoes at the growing stage because Nanny will tell you. As we are beta testing it, I double checked the pH and conductivity with a manual meter: Nanny’s measurements were good.
Transplanting the plantlets was ridiculously easy. I directly buried the jiffies into the the arlite, trying to cover them completely. I plugged the small air pump to the timer, programmed the other timer for the LEDs and put Nanny’s sensors in the reservoir.
Then I just stared at my little sprouts for about 30 minutes. They look beautiful.
