Sounds like me. when I started growing good was when I moved to college and didn't know anyone to get stuff from, so I sold everything I had put into my car (speakers, tvs, cameras, rims, etc) and used that to get a 400w light, a tent, scrubber, and exhaust fan. I used Home Depot buckets as a DWC, so the hydro setup cost maybe $20... Also after I sold all that stuff I quit getting pulled over every 20 feet lol, whod of thunk? Win-win. I only drive stock now.
A friend gave me the bible, which I still have lol. I have upgraded everything by now lol, the longer you grow the more you can think of to upgrade as time goes on... Then you end up with an attic full of stuff you don't use anymore like me.
I'd sell it on Craigslist but don't trust people very much lol, so it sits and collects dust.
