Calculating the safe maximum weight (wet soil, plants, water, people) your roof can support.

"You’re right—let’s lock those numbers down! We need facts to truly bust the fear. Myth Busted #1: Your roof is far stronger than you think. Standard residential terraces are designed to handle a uniform load of at least 150 to 200 kilograms per square meter (kg/m²). That is the actual, verified standard for heavy furniture and people. Can your roof handle a 100-kilogram person standing on one spot? Absolutely, YES! That’s a temporary point load it's built to withstand.

Now, look at your roof top / balcony farm: a properly laid out garden, using lightweight media in grow bags, typically averages only about 15 to 25 kg/m² across the entire surface. Even your heaviest single container, fully saturated, rarely exceeds 50 kilograms locally. The structural caution isn't about the total load; it’s about avoiding permanent, massive structures. The scientific data confirms it: You are good to grow!"
