O... a few more pictures... then I'll explain my techniques..
everything you see s on my roof top garden.. so changing over from building with 2x green lumber for planters and such.. saves a tremendeous amount of dead load weight... and t has the ability to medate the temperature flux... cooler in the summer.. [ my roof surface gets up to 165* F quite easly.. but the foam s slow to transfer it to the drt nside ] I can water with cold water.. and hours later the soil is still cooler.. and it's warmer n the winter.. as the daytme highs are carred over for hours.. and it has the benefit of not warming up quicly on a bright sunny winter day and havng things want to break dormantcy... sap flowing.. only to have the cell structure rupture with the cold nights.. ... one of the biggest winter problems.. as the roof surface heats up readily then also.. and sun on the planters will do that anywhere also...
so this year I'm running out of space for planters... here's a container inside the foam skylight in the previous picture.. everything seen is foam.. aside from the starway
