👉UPDATE 25.07. - The plants are alive and have already grown to 3-5 cm!
In the early stages, I placed plastic cups over the plants to increase humidity. It was hot, and despite using a humidifier, I struggled with very low humidity for two days. However, the plants look healthy.
👉UPDATE 26.07. - The plants are thirsty - when should I start fertilizing?
I last watered them on 24.07 with 200-300 ml, and the soil is already dry today. I'll water them with another 200-300 ml but will research whether this watering ratio is appropriate for my 11 L pots. They are growing, and the serrated leaves are becoming stronger.
