Kale: this vegetable essentially doesn’t need quite a lot amount of light as it will yield remarkably in low light conditions. The only thing that you are likely to notice is that kale grown in the shade tends to have relatively reduced growth compared to the one grown in the full sunlight.
Lettuce: experts recommend that you grow lettuce in the shade in order to protect its leaves from the scorching effects of the sun. Growing lattice in the shade is very important as it helps prevent the vegetable from bolting rather quickly. Of course, you should expect that your lettuce will take a little more time to grow to maturity compared to the one grown in the sun.
