The black water for all plants that grow in soil at home. #lessonsfromplants #shortvideo #plants

In this follow-up experiment, I adjusted my setup to ensure fair testing conditions. We’re analyzing how battery residues affect plant growth by comparing contaminated soil with clean soil. Now, both groups of lettuce plants have waterproof trays to avoid environmental variables. I’ll be observing root development, color changes, and growth rate. Will toxic residues impact their health?
