I bought everything individually. As for set up time- I've tweaked things over the past two years but it now takes me longer to clean up and sterilize everything than it does to set it up.
Ball park numbers: (been a few years)
Tent- $120
6" inline w/carbon filter- $140
4"inline- $60
Igloo cooler- $15
Ice probe chiller- $100
Light- $120
Corner fan- $10
Air pump- $40
Airstones and tubing- $40
Room thermometer/Rez therm -$15
Scrog- $10 in supplies from the hardware store.
Nutrients- $40
So roughlyyyyyyy... idk, $700 or so total?
If I left something out and you wanna know, feel free to ask.
