Looks like a good start. Keep in mind that your babies will grow quickly. How much space do you have between the top of your planters and the highest light placement? I think your OK now, as you can have the plants as close to 2-3 inches from the lights. Your little babies will reach almost 8 inches in couple of weeks. I would suggest an old dresser, or stereo cabinet that you convert. It will matain your stealth, and provide room for growth. Looking forward to your results.
