For one plant you would want a space at least 18" x 18", but a little bigger would be better.

The minimum set up would be dirt, a watering can and some fertilizer, a couple of small flouros for the lights, and a small computer fan or something to provide a little air flow. I suppose with a little digging this stuff could cost you from 0 to 40 dollars.

The minimum set up to reduce odor would be to grow some weed that is not very potent. The next choice would be to buy some cheap odor control that you just set in your room (like a jar of odor eating stuff they make for this). The next step up is to buy an air purifyer like Ionic Breeze. The next step after that is the right one, and that is to buy a carbon filter. I suppose you could also look into ozone generators and stuff like that, but that wouldn't be the minimum set up. I don't know how important stealth is to you, but if you don't do something, and you grow decent weed, people will smell it when it starts to bloom.

That said, I would not consider setting up a grow area the minimal way. I have done it and it was just a waste of time. Your plant will grow and you will get weed. Unless you just like horticulture though, I would save your money until you can get or make a cheap hydro set up and HID light similar to this:

cheapo DWC (deep water culture) hydro set up: $15
home made 150 watt HID light: $35
ventalation: $50
nutrients, PH up or down, PH pen: $50
sweet, beautiful weed that you nurtured yourself: priceless

Growing with flouros is a waste of effort unless you use a shitload of them.
Opie Yutts Reviewed by Opie Yutts on . Stupid questions for the experts Ok, so this has probably been asked before... I would like to grow just basically one plant in my closet for personal use, what is the minimum setup and cheapest way to do this? Also, is it going to smell like a motherfucker and stink up my whole closet. Thanks Rating: 5
