Jared, think you should try something simple for your first effort. I got every single thing off ebay for less than £30, everything. Keep it cheap and easy why you learn. make a simple box of wood, consider where you are gonna keep it and that will dictate your size. throw a few pc fans in, one flowing the air in, reverse the other and air flows out. Grab a few old mobile chargers, cut the ends of and attach to the red and black wires on the fan, chop of the spare one, usually blue. buy a sheet of mylar, or paint the insides white. get a couple of cfl's or a nice big one and attach via a simple light fitting socket, consider your wiring I always you lighting wire aposed to general wiring to prevent any fire risks. I got a cheap thermometer, humidty gage and that was it.
wiring - £4.00
Bulb - £12.00
fitting - £2.50
Mylar - £3.00
pc fans - £5.00
mobile chargers- all ready had these.
Simple, purchases for a simple first time grow. Now the important thing, dont skimp on your soil and perlite etc,nutes,water and attention to detail. Above all enjoy growing, by keeping it cheap you stand to lose nothing big whilst you learn the ropes. Dont spend the earth and get down when things go wrong. keep your first grow realistic and listen to others, too much reading can be confusing, but filter the consistent guidelines and enjoy your yield if it happens.
