English for “to stretch”. When the plants stretch, it means that they grow with a large distance between the stem joints. This is due to excessive heat, lack of light or fertiliser problems. However, it is normal for photosensitive plants to stretch the first few weeks of flowering. This is because their circadian rhythm suddenly changes from 18 hours of light a day to 12 hours of light a day, so they seek out the light and stretch higher to “reach” it until they adjust to the new circadian rhythm.
