I also bought a "potato bag" which I'm looking forward to try getting a crop from. Supposedly you can get a 13lb yield from one bag and you don't need to dig or have yard space.... sounds cool I'll advise if it works.

Of course you can grow tomatoes in a 5 gal bucket, but that doesn't mean the endeavor is worthwhile in terms of cost or efficiency, and if it's not, then what's the point other than satisfying some need for a hobby that wastes more resources than it provides.

I would like to know if anyone is doing hydroponics (for food thank you). It's something that's has interested me for quite a while, but I can't seem to decide if it is actually cost effective. So far, beyond the hobby value and organic produce perks, I can't seem to find a set up that would really be worth the investment.
FYI-Growing is growing, certain plants have certain requirements, but as long as you meet them then all is well. If you are growing lettuce, tomatoes, aubergines, or a little cannabis indica, it's all a matter of just providing what the plants need. All that differs is pH, nutrient, water, humidity, and light requirement's.
Yes I grow tomatoes, zuchinni, rasberries, blueberries, blackberries, orchids, and some of my mushrooms hydroponically. I am currently experimenting/trying to perfect hydro organic techniques. (hydro growing methods using only organic nutrients) Yes though, it is very cost efficient and there are even ways of setting it up so that you do not need to depend on the electricity usually needed for pumps and what not.
Depending on what you are trying to grow, hydroponics, or aqua culture usually produce both an increase in yeilds by 30%, and a decrease in growing time by the same percentage, on average.
What kind of things do you want to grow? Tell me and I can probably help you out.
On average try to stay away from commercial hydroponic systems, One can usually build their own at a fraction of the cost.
The most economical medium I have ever used for hydro was lava rock, which can be purchased at most hardware stores for as little as a dollar fifty for a shovel full. Lava rock is almost perfectly neutral as far as Ph is concerned, and contains many trace elements. It is a good way to start for the beginner, without having to get into stabilizing pH for rockwool, or whatever.
Once again tell me what you want to grow, and I can probably give you an idea of how to go about it.
Depending on what you want to grow, on average setting up a beginning Hydro system will cost you anywhere from 50 to a couple of hundred dollars. You can do it for cheaper if you are willling to put a little effort into building things yourself as I already mentioned.
Figure- 20 for containers, 20 for a pump, 20 for a H2O resevoir, 20 -50 for nutrients, initial investment of 75 for an EEC meter to test conductivity. 20 or so for substrate (lava rock)....
Of course this is all for outdoor use...If you want to grow inside then you have to figure in an additional 200 or 300 for a high intensity discharge lamp (1000 wt HPS, or MH). One does not need to grow indoors though to grow hydroponically.
What you also need to realize is-The relatively high start up cost is offset after two or three harvest, considering the fertilizer,water and space being conserved. True it might cost more than digging some manure into the ground and watering every day, but in the long run it is much cheaper, and ecologically friendly (cosidering you are not using rockwool).
