Q.hydroponics and upside down growing
I like the idea of growing your plants upside down and the benefits that come from it. Now I have grown with hydroponics, but not for long. Can you grow upside down and still use the hydroponics?
This article goes over the basics of upside down planting: https://www.gardeningknowhow.com/special/containers/upside-down-gardening.htm
Theoretically, you could use a hydroponic system with upside down arrangement, if you make some provision for catching the nutrient solution that would drip from the area around the stem that emerges from the planter. You could also look into other approaches, such as aeroponic gardening. This article will tell you more: https://www.gardeningknowhow.com/special/containers/hydroponic-gardening-indoors.htm
There are thousands of alternative planting methods, and if you want to try some, you can research and experiment to your heart's content. Happy Gardening.
