What you need to succeed is the proper frequencies of light with enough photons per sqft to build a big bush.
Bottom line, I doubt that it's a viable plan.
about that, is there a collection somewhere of the sets of formula's nescicary to convert all the different ways people reference lighting equiptment into something as beautifully simple as photons per square foot?

I'm kind of glad you doubt the viabilty of growing with light originated from lasers I like a little controversy. I guess I should rephrase my saying "at least I'll be the first to fail at it" I like the way Edison put it... "I have not failed. I have just found ten thousand ways that won't work".
