I installed a vertical garden like the trendy ones you see now, with pots stacked on top of each other, but the plants at the bottom get very little light and the water doesn't reach them properly. The vegetables at the top grow normally instead. What am I doing wrong with the watering?
The problem is that in vertical gardens, water tends to run down quickly without stopping at the intermediate pots, especially if you're using a poorly regulated drip irrigation system. Try using drip irrigation with more delivery points for each level, or better yet switch to a capillary system if possible. As for light, the pots at the bottom suffer because the ones above cast shade, so either move them to a brighter spot or add a small LED lamp dedicated to the lower levels.
