Vertical hydroponic/aquaponic gardens are the way of the future.
Adjustable wing reflectors are pretty cheap and will allow you to expand the footprint of your garden without having to add more lights and use more energy. About 50 watts per square foot is necessary for flowering/fruiting plants, but leafy vegetables can get by with a little less. Let me know if you're interested. We have a ton of used equipment for sale.
Are you feeding them Botanicare products? I thought I saw a label in the background.
