That's why I am testing 2 of the 144x5 reflectors for alot more even coverage. Not sure how the buds are going to come out, but it's what my FastBuds BlackBerry are under and they are looking great. You can spread em out. The intensity is the greatest right underneath but even though it's significantly lower farther out it still seems to grow me good dense buds to the edge of the tent, and that's with a 900, so you 1200 should be no problem.
