So do you think going to 600 W would cover it all ok?

So what about a 4 tube T5 set up that is 2' long? Would that direct enough light at 3 plants you think?

Not in my opinion. Some people love t5 lights, but they just don't compare to hid lighting in terms of output per Watt.

T5`s are great to a certain point. For seedlings, clones and short term veg growth they work great but once plants get around 2.5-3 feet or taller the lower growth will start to suffer from the lack of light penetration. I have a 100 watt 2X2 4 bulb T5 grow light I use for seedlings and small clones I also have a 452 watt 8 bulb 2X4 grow light that I use for short term vegging and a mother plant. For flowering they go under the 1k HPS light to finish out.
