Am planning to add some raised bed planting area along the south side of the GH building with cement blocks, ...
Great potting bench!
If you mean "cinder blocks", their thickness takes up a lot of floor space inside a crowded greenhouse.
I make raised beds outdoors by using concrete paving stones stood up on end and leaning inwards slightly. Since they are only 3/4" thick or 1" thick, they take up much less space than cinder blocks.
However, the tallest wall I make with them is only 16" tall, and I should straighten out their leaning angle every few years.
8" x 16" x 3/4" : make an 8" wall or a 16" wall
12" x 12" x 1" : make a 12" wall
8 x 16 pavers:
12" x 12" in foreground, 8x16 in the background. You can see how the 12x12 pavers are thicker.
