I always wanted to try it on a small scale just to play around with. Do you find much advantage over soil that makes it worth your while?
I'm also fascinated by the process. What makes it better than dirt gardening?
There are several advantages:
1. Yield is much greater. One source compared the yield for hydroponic and conventional farming of tomatoes. They showed 5 to 10 tons per acre for conventional farming and 300 tons for hydroponic farming.
2. Plants are usually healthier. The plants receive all the water they need. They are not dependant on rainfall. They also receive the exact nutrients they need to to flourish. The fertilizer can be blended and targeted for a particular plant. A more general blend or all purpose fertilizer can also be purchased if you wish to grow a variety of plants.
3. Less work. I spend about 3 minutes a day checking the nutrient solution each day. The best part is I never need to hoe or till.
4. Did I mention I never have to hoe or till!!!!
5. It is perfect for people with limited space. Although I have several acres I could use for a garden I will never go back to using a hoe or tiller. Too hot, dirty and time consuming.
How are the plants suspended over the solution?
The plants are “planted “in some sort of inert media. There are commercial mediums available. Many people use coconut husk, washed gravel, sand, or Cyprus mulch. The solution is pumped to the top of the medium and drains out the bottom and is returned to the reservoir to be recalculated. This in only one way of delivering the nutrients to the plant.
I have to go now. I wrote this on the fly. If this is not clear or you have more question I will try to answer them later tonight.
