Transplanting leggy seedlings
Updated: 2 days ago
While starting plants from seeds the developing seedlings will grow in the direction of the light. This is called Phototropism.
If the light source for your growing seedlings is not strong enough or does not contain the proper spectrum of light then the cells of the developing seedling can develop thin cell walls and elongate. Thus, results in tall spindly seedlings that can not support their own weight.
