I like your lighting uint. It will be interesting to see how your new system works out over time.
I have basically the same system as Tadd and have already seen a remarkable difference in plants put on the shelf vs. plants put inside the containers with rocks and water to increase humidity.
I just looks like the hot lights and with the fan running all the time you are inviting dry conditions. Time will tell. Just keep an eye on those beauties!
Keep us posted!
