I sowed 12 seeds of blue tomatoes OSU 12 december.
I have planted 9 plantations on 31january. I kept plantations inside on an electric propagator.
On 7 februari, I planted plantations in greenhouse in a cage frigolite on a heating carpet enlightened by red and blue leds.
It made very cold outside but plantations resisted.
13/03, I placed 4 plantations in the greenhouse on the table and they underwent the cold during a week (minimum 2 - 5 °C at night, 15 °c in the daytime).
The blue color appeared on stalks and nervures.
Here is the bottom of the leaves of this 8 cm plantation
