the first two weeks were rather cloudy and cold. now the sun starts to shine all day and i have around 25-30 degrees in the greenhouse. when the sun shines all day, the plants have 8 hours direkt sunshine and 6- 7 hours of normal daylight.
@IvyGrows, sure, i could gave it two more weeks, but most of the cola are at the stage i want them to be. i checked the trichomes with a 60x magnifying glass
