Plants look great. If you want bushier you can set each pot on an upside down pot to put them
closer to the light. If seedlings are too far from their light (and energy) source they will stretch towards the light
as they veg. This makes for long internodal distances (bad!) leading to tall skinny plants. Most of us prefer bushy
over tall, eh? You got a lot of room in your space -- either lower the light or raise the pots.
Good luck, BigSteve.
