I just dropped the price of
the permaculture playing cards
for a wee bit.

 

 

uses include:
- infecting brains with permaculture
- convincing folks that you are not crazy
- gift giving obligations
- stocking stuffer
- gambling distraction
- an hour or two of reading
- find the needle
- find the 26 hidden names

Thanks for the welcome, Tim. This is certainly a warm online community!

Our green roof builder (Leslie Doyle at Restoration Gardens) gives me these general rules of thumb for fully saturated green roof weights:

Extensive (thin growing medium, mostly sedum-based plantings): 10-35 lb/sf
Semi-intensive (soil/growing medium hybrid, flowers and grasses): 35-50 lb/sf
Intensive (soil, flowers, grasses, vegetables & small shrubs): 50-300 lb/sf

These are still pretty wide ranges, but will give you some idea. Of course, you must add the full snow load to these figures in cold climates.

Hope this helps!

Thanks Chris
 
He was giving me directions and I was powerless to resist. I cannot resist this tiny ad:
