|I am planning on growing Lettuce indoor, under fluorescent lights.
Now I know from others that have done this, that low growing Mesclun varieties are relatively simple to grow, but what I'm wondering is whether I would be able to grow an Iceberg such as "summertime" in this way.
Do they need a deeper soil depth because of the size of the head?
|You can grow most any kind of lettuce indoors under fluorescent lights, including Iceberg. Lettuce develops a fibrous root mass so plan on providing a soil depth of 8"-12" for the larger lettuce varieties. Keep the light source only a few inches from the tops of the plants (moving it up as the plants grow) to keep the heads compact and the tissues tender. Good luck with your project!|
