I too have a low-light/tech HEX tank, mine is 40g (24"tall). So far, I have been having the same issues with having such a deep tank and live plants. I have two 15 watt 24" tubes, and a reptile spiral tube coralife 20watt 50/50 bulb. I'm injecting DIY CO2 with the red sea 500 reactor (worth the $) and the plants are staying alive, but it's definately obvious that they aren't getting enough light. So I went out and bought all the items for a DIY 70 watt Halide system, but realized that I might still have the same problems with the 1.75w/g, and decided to get the 150 instead. I'll keep you posted on my progress and maybe one of these days I'll finally post up the pictures I've been taking. If you're interested, I have ALL of the items practically ready to install for a DIY 70 watt (10K Double Ended HQI, halogen housing, ballast and wire) I was going to post up on ebay if you are interested...? I can take pictures of it for you. My substrate is the red sea or something like that aquatic plant soil topped with homedepot silicate light-grey sand.
