Getting overwhelmed setting up an LED tent system...help!

[aerides]

So if the whole point was to save money, I understand your frustration. If you can take that off the table, for now, you could start realizing and enjoying working with the increased flexibility you would have in designing an LED growing space for orchids. In flexibility, LEDs beat HID hands down.
In other words, you're beating your head against a wall. Stop doing that. Give yourself the freedom and enjoyment of designing your space the way you want it. Then you can truly assess the cost/benefit factor.
LEDs are available in so many forms, colors and strengths, that they offer amazing flexibility. Think beyond the bars. For example, you could use everyday spots for overhead, and bars for under shelves or vertically. You don't have to buy everything from this guy (although it doesn't necessarily sound like he's trying to bilk you).
I hope this helps.
