Yes as a starter, one wall. I want to keep it simple till I get a handle on it.
Ok so at first blush, I'm running the calculation of trellis area vs light output and I'm thinking you'll want at least 480W if not closer to the full 600W. 600W divided by 4x5ft²=20ft² is 30W/ft² which is a good number for high efficiency LED.
You may want to put a dimmer on it and mount it so you can move the light to be closer to the plant at first, them further as it gets bigger and you turn up the power.
I suggest looking at sativa dominant strains so your plant will grow and stretch to fill in all that surface area.
Because of the veg time required, you may want to start a second plant well before the first one even blooms because it can take a few months to grow the plant big enough to do such a trellis justice.
A thirty gallon pot is if anything overkill; I was growing 6' tall plants yielding as much as 27oz using 5 gallon buckets!
While CO2 would help things grow faster it isn't necessary. Another idea is to look into triacontanol, a plant growth regulator found in most plants, especially alfalfa. Unlike most PGRs, it's not harmful and can really accelerate growth in veg and early bloom.
You'll want to keep temps in the tent in the mid 80s for best growth; plants like it warmer when using LED light because they emit much less infrared. This is why LED lights are more efficient than high intensity discharge lighting.
Folks also report that their plants want more calcium and magnesium under LED lights. I've found that higher nutrient levels in general work out well.
Hang your panel with a 6" gap behind it for good air flow to avoid mildew issues.
For the first part of the plant's life, you really want to light it from above because plants are phototropic; they grow towards the light source. Only when it has filled in most of the trellis will you want to hang the light vertically in front of the trellis, likely when you're ready to flip to bloom. Don't worry about the bottom of the plant getting inadequate lighting; the tent will reflect plenty onto the lower branches.
That should get you started! Link me to your thread and I'll help out as you go along.
