It's not the amount of light you have to worry about, it's the heat. Make sure you have a fan blowing across the tops of the seedlings, and you'll be good to go under your lights. Also, remember that since your flouros aren't very intense, you'll want to get them VERY close to your new seedlings to prevent stretch
EDIT: To answer your question, I would put em right into the box after they have germed. |
