Hydroponics
Sep 11 2010, 1:32 AM EDT
Sorry if someone else has brought this up but I dont think so. Hydroponics (http://en.wikipedia.org/wiki/Hydroponics) are very useful , and easy to do.I am currently farming lettuce and tomatoes and am experimenting with potatoes. So, what is all of your opinions on hydroponics.
Do you find this valuable?

I had the impression its very high-tech' pumps (electricity) chemicals, etc. That approach for me seems less sustainable in the long run.All the people I knew who did it were on artificial lighting, forced growth systems for a 'specific' crop though. Thought about mushrooms? they are quite easy and a great source of protein. Do you find this valuable? |

I have used hydroponics several times. I won't say why.What I can say is that the system will use a lot of water, and depending on if you go for a closed or open circuit system, you need pumps, or some other way to get the water back to the beginning. Closed circuit means the water is cycled over and over. You still need to change the water every three weeks to prevent salt build-up, nutrient imbalances, virii and bacteria build-up. But you need less fertilizer. Open circuit uses a constant fresh supply of water. No risk of build-ups, because that all runs off and to waste. No need for pumps if the water source is higher than the plants, and the run-off point is lower. But the use of fertilizer is many times higher. Hydroponics would only be suitable for areas where there is an abundance of water, you can fashion a pump system, and the ground cannot normally hold plants (deserts, because sand is too fine for a supporting root system). Everywhere else, soil is the way to go. Soil acts as a nutrient buffer, it retains water until needed, and it keeps it's bacteria levels in check with other, more frindly bacteria. 1 out of 1 found this valuable. Do you? |

I've looked at hydroponics and with the water factor, I'd rather grow in the ground.
