My Green roof — Spring 2018 update
It works! The structure is holding up pretty well! I have plenty of stuff to eat and a lot to tell!
I have a few vases with more lettuce in one of my balconies. The soil of these is nearly 100% home made (out of my compost). I threw in some seeds, and here’s the result:
Last summer
Last summer was pretty hot, and my garden suffered from it. I was expecting a big crop of tomatoes, but that didn’t happened because of the heat and direct sunlight. However, I got a few surprises:
For this summer I will introduce some shade in the garden, so I can grow tomatoes and other vegetables during the hot days that are coming. Here’s a very badly drawn diagram of the plan.
And here are the first steps of the implementation:
Also during the winter I did an estimate of how much weight I have in the roof. Turns out that today I have nearly 800 liters of compost / soil inside the box. With each liter of wet soil with a weight of 0.65 kg, the dimensions of the box and estimated structure weight, I calculated that I have about 200 kg per square meter, what is acceptable according to the building technical information.
I am happy with my green roof!
