Another illustration would help me better visualize where to place the five bulbs. One in the middle is obvious, but do the other four go in the corners? How high is best?
I really appreciated the math oriented discussion above, as I tend to think theoretically.
Once, I shied away from hydroponics. Now I design my own systems for paying clients. Once, I ran an open room- now I'm running a water chilled, controlled environment- and again, design them for others. Once, I thought that a level trellis under overhead lighting was the preferred approach. Just one more aspect to re-think.
I've learned so much doing this I honestly feel that by comparison, getting my college degree was a waste of time and money.
