What about using a single 3 or 4 gallon bucket?

It has to be air tight

Has anyone considered, or will consider - making one - for me haha.
If i paid for everything, paid for postage, and time put in (beer money) - how about it?

I just know i am useless at this kind of thing

Could you use nutrafin co2 system with the sugar and yeast mixture instead of buying their tablet refils. Also whilst in my lfs I saw a jbl cheap co2 kit which uses fermentation so I guess you could use this if you didn't want to make your own. Any thoughts on this.
