Heading off to Wal-Mart soon and I'm trying to work around a mostly ~$150 budget. I already bought the soil and the nutes, but I'm still deciding on an effective setup. My space is roughly 3.5 x 3.5 x 3.5 ft here. I was thinking about doing a stealth PC case. What do you guys recommend as far as fans? Carbon scrubbers? Tape? etc?
