hey bro, good to see you haven't given up.

if cash is an issue you might want to consider CFL's, first because they are
relatively cheap and easy to find, plus, you can add them as you can afford
them. another plus is that the heat is more evenly distributed so it's less of
an issue.

also, another big plus is that you're able to customize the spectrum's of light
you use, you'll want mostly blue or cool light (5000Kelvin and up) for vegging
and mostly red or warm light (2700Kelvin and lower) for flowering.

here are a few pics of my old light set-up and the only reason i'm not still using
them is because i'm building a new flowering cab that'll be powered by 2 new
150watt HPS lights i picked up before Xmas.

i actually grew with CFL's exclusively for over a year with excellent results
so i'll include a couple of bud shots so you can see what CFL's will produce.

anyway, good luck, if you're persistent, you will succeed.
