I have been thinking about going completely with t5's. I came across some t5 ballasts for 48" bulbs. Unfortunately all the reflectors I have seen are too wide to fit as many lights as I would like in my canopy. I was thinking of maybe just cover the whole lid in mylar, or polished aluminum and essentially make it one giant reflector. Would this work? Any other suggestions? I would like to keep sps, so I know I need good lighting. Below is a rough drawing of what I want to do. The dimensions inside the canopy I have to work with are 60" x 15" and it is a flat back hex shape
Thanks
