Ok, so I understand that MH is more "efficient" than T5 in that it produces more lumens per watt. However, from what I've read, T5 has the following advantages:

1. runs cooler so can be placed closer to plants so less diminishing of light compared to MH

2. produces a greater % of light in the spectrums that plants actually use to grow.

I don't care about initial cost of equipment/ballasts/etc... Plants need a certain amount of footcandles of light in certain light spectrums to achieve growth and flowering. My question is, considering all of these factors, which will use less wattage while achieving the necessary footcandles at the plant, a T5 setup or a MH/HPS setup?
