If you mean when you have planted on them the first time to the smaller plant pots so I recommend a temperature between 16 – 18 degrees. This in order to get powerful fine plants. Normal room temperature usually gives lighter plants when they are in the beginning is growing too fast and can become long and rickety. These chiliplantor usually gives less large crop as if they had been developed under optimal conditions.
If you have a basement or a room where you can lower the temperature so it is a perfect place to power up their chiliplantor on.
