I came across this excellent summation of the advantages of growing in hydro, as opposed to soil. It was in a blog posted by Anne Harvester, and I’m taking the liberty of sampling it here:
“• Smaller deep water culture systems are less work than soil gardens since there is obviously no soil to till as well as no weeds to pull. Since there is no soil, you needn’t worry about soil born diseases, either.
• Hydroponics uses only a small fraction of the water a soil garden requires. There is no water wasted or stolen by weeds.
• Since it is you that is providing the needed nutrients, you can be sure that the plants receive the exact amount they need. This causes them to grow more rapidly while also producing bigger yields.
• It’s been shown that hydroponic systems produce is much higher in nutritional value than ordinary crops grown in fields. It is also thought to tastes better than field-grown produce, as well.
• You can grow your plants on a year-round basis when growing indoors with LED grow lights or in a greenhouse with their grow lights.
•
So as you can see, hydroponic growing is perfect for the hobby gardener or the farmer growing crops such as tomatoes, cucumbers and peppers, leafy crops, like lettuce and herbs and flowing plants.”

I’d just like to say that most of the hydroponics I do is deep water culture. Not every plant thrives in it but most do and it’s really easy to maintain.
My little “salad machine” grows more lettuce than my wife and I can keep up with and hardly takes up any room.
