Welcome to the forum. My 2 cents. Either experiment with outdoor growing or spend 1000$, and do a shit ton of reading, and start completely over. Unfortunately your current set up wont ever produce any buds.
I think:
Don't bother growing indoors unless u can use HID's
U need a tent or a well constructed space to grow indoors in.
U need ventilation and temperature, humidity controls
The single most important factor leading to success is environment control
Use good genetics (either known quality seeds or clones)
Tinfoil is a little silly. Reminds me of the trailer park boys tv show.
Miracle grow weed is like dusting a good bud in chemicals and smoking it.

Finish out your grow to help you learn what's up if u like. Make sure u are reading a lot and taking it in, focus on your next
grow.

Hope this is helpful info for you.

You don't really have to spend a thousand dollars but u need a lamp, ballast, inline fan(s), oscillating fan(s), and some good dirt, nutes of your choosing, room/box/tent construction costs, and some other stuff.
