That's a common misconception, it's actually quite easy once you have been through the learning phase and what impact PH and nutrient strength have on your plants... And really it's not that labor intensive than any other garden, you do need to change the nutrient tank once every 2 weeks but that's the hardest thing there is, that only takes 15 mins.I have always been interested in hydroponics, but it seems so difficult, expensive and labor intensive. I have not done any major research on it, though, so I could be wrong.
But if you still don't want to do that as I said before Hydroponic nutrients mixed in with water and tipped onto soil also works well, and will increase the health and size of your plants.
