If you can afford concrete, pour concrete.
I used cinder blocks personally, because $$

I’ve made it with similar blocks (6” by 8”). I’ve leveled the ground and put around 6” of 0-3/4 crush stones under. I recommend to stack at least 2 layers of blocks.

We put up a small (6×10) greenhouse last month and used these exact blocks. Just one row tall, and the block is sitting on top of an existing concrete patio. We thought about doing a second row to get more headroom in the greenhouse, but neither one of use wanted to haul more block. The greenhouse is attached to the block with concrete anchors and the brackets that came with the greenhouse. We’re very happy with how it turned out.
