Most Overlooked Piece of Hydroponic Equipment?
I was trying, vainly, to organize my hydroponic supplies and equipment and I started wondering what it is that most people either forget, take for granted the importance of, or otherwise just overlook.
At first I thought probably it would be lights, but a lot of people grow with natural light. It's still pretty high up there on the list of equipment many hydroponic hobbyists overlook, though.
Probably not the system itself, probably not plants even though I think there's definitely some room to discount the importance of good plants.
I think it's probably the nutrients themselves. Getting the right nutrition for your plants is especially important in hydroponics and I know a lot of people are trying to pick the right kind of Miracle Gro off the shelf at Walmart. As I recently learned, a good quality hydroponic nutrient is amazingly easier to work with than a bad one. I tried Advanced Nutrients three part nutrient and it was great.
But I'm more interested in what everyone else thinks. What's the most commonly overlooked piece of hydroponic equipment?
