well, first off 32 gallons is way too much for 1 plant, except if you are planning to grow a redwood. the general rule is 1 gallon for each foot of the flowering plant, i.e 2 gallons for a 2 foot plant, this will save u alot of space. as for the soft white cfls, soft white is not a good spectrum for growing, use a 5000k or higher "daylight" bulb for the beginning, and add a lower 3000k and lower "warm" white bulb for the flowering stage.you can find these bulb usually at home depot or lowes and they use standard household sockets.as for the amount of light, the rule would be at least 2500 lumens per square foot of growing space, but remember you cant over do it the more light the better. i do like the idea of using empty doritos bags as reflective material lol.
