i made a few of those, and donated them when i lived in oregon. they work well, but can be a little work. the main problem is usually, the tub is too smal for the amount of plants feeding out of it. if you have 6 plants feeding/drinking out of an 8 gallon (will be less) bubbler, you can expect wild ph swings. the tub will start filling up with roots, then there will be even less room for water. another thing that can be a problem is draining and cleaning the tub. there are 2 schools of thought, some drain and clean weekly, others wait 2 weeks. personally, i'd do it weekly. you can see how this can get labor intensive. ideally, you'd want 2 tubs so you could just swap one for the other. another thing that can become a real issue is keeping the rez/tub temps. down in the summer. this can cause problems quick. easily solved if you buy a chiller, but they are very expensive. some folks freeze plastic bottles of water and drop them in the tub. only problem there is, it'll raise the level of the tub if you need to use several, so in a smaller tub, it wold happen quick. if you keep the tub in a room with very low ambient temps. you'd prob. do o.k. what i'd do is use the one coming as a model and buy a 30 gallon tub from wally mart. it's a little work, but you could pretty much utilize most of the stuff coming. you prob. don't need a hydro book. i'd bet a shiny nickel that adequate instructions are included with what's coming. from there, you just need to learn how to control ph, and adjusting ppm's in feeding. it sounds more complicated than it is.
