Hey Phrankie glad to here your not giving up. But man I'll tell ya unless you can afford the stuff for growing indoors or your very good at making your own things, this hobby does and will get expensive. I run just a small closet setup and with my soils, nutes, lights 400watt HPS, CFL's and florus , intake and exhaust fans, oscilating fan, PH meter, PH down and up, timers, power strips, containers to grow in, scrubber, and the other odds and ends that I use, I'm sure I have well over $600 in it if not more and that does'nt include electric bill. Now grant it some of these items are longer term investments, but items will need to be replaced once in a while like bulbs that go bad or if a fan dies ect.. My suggestion to you or any one new to indoor growing is to build your room and have all the supply's you need before you even drop you 1st seeds. Test run your room for a few days to work all the bugs out incase you need to change something. Get it dialed in 1st, then do your homework on the growing details you'll need and your 1st grow and every grow after that will be top notch instead of "If it becomes a complete failure, i will just chalk it up as a learning experience". Why not grow weed right the 1st time and every time there after. But as I stated above glad to see your not giving up as most people do, it's something that takes time, money, knowledge and most importantly patience. Good luck on your endevours...take care..
