It is hard to plan the best solution on what are you supposed to do if your roof was totally gone or destroyed. Choosing the best quality is an advantage because it is also long lasting and could fight against weather changes.

Here's a bit more info on the Ansonia:

As for Sustainable South Bronx, their roof is growing vegetation, but not edible varieties.

they've done one at eagle st farm

Roofs that can't support soil-based agriculture can often support lighter-weight hydroponic greenhouses, which have many additional advantages. Gotham Greens is building a huge, commercial hydroponic farm atop a building in Brooklyn. There's a lot of info about it at: http://gothamgreens.com/ The technique has been modeled aboard the Science Barge, currently docked in the Hudson River at Yonkers.

Sustainable South Bronx, an environmental justice organization in Hunt's Point, has had a vegetable-growing green roof for at least three years.

should they also mention the "white roofs" program: http://www.nyc.gov/html/dob/html/sustainability/white_roof_works.shtml

is this recommended if we can't grow food on our roofs?

Can't stop thinking about the roof farm that the Ansonia had on their roof to feed the residents of the building when it opened in the late 1800s. Cows for milk, chickens for eggs, etc.

With all of the soot that shows up on my window sills, it makes me wonder if the air and (acid rain) is safe for growing food on a roof garden? Any information or research about that?

http://www.GaiaSoil.com is a more direct link to look at this soil mixture

mention is worth making of gaia institute's green roof soil mixture which is lighter weight mix than soil, check it out at

Thanks for this program, Leonard...

I hope that more people realize that a little farm is possible on their roofs, even if they are not able to make a genuine, intensive greenroof. I rent, so no greenroof for me; it would be more than my landlord could bear.

I am a garden designer and gardener - and have extended my tiny terrace garden by adding an even smaller roof farm to the silver tartop above my head.

It is very rewarding to grow one's own vegetables and fruit even on a small, non sustainable scale.
