The Q&A Archives: Lanky Seedlings

Question: What do I need to do to prevent my new seedling from being
so lanky? They are really long with little to no foliar growth? I keep them under lights and used heat mat to start the seeds. I started to add small amount of fertilizer after 2nd or 3rd set of leaves.

Answer: Seedlings can get lanky if they're not getting enough light. If you're using fluorescent lights, place the seedlings just 2"-4" below the light source and raise the lights as the seedlings grow. Leave the lights on 12-14 hours each day and turn them out at night. Providing proper light should help your seedlings develop into stout and sturdy little plants.
