Are you growing outdoors or indoors by a window? If the latter, you may end up disappointed as this often fails due to lack of light.

As for your question, an increasing photo-period is actually great for a seedling. Initially being in less light, such as 12/12 the seedling was able to better develop a thorough root structure. The seedling views an increasing photo-period as Springtime and time for rapid growth. Since it already has developed a good root structure, this rapid growth will be above the soil!

God luck and keep us updated

Peace
