Shred zucchini and add to a large mixing bowl.
In another large mixing bowl combine flour, baking powder, baking soda, salt, cardamom, cinnamon, and nutmeg. Toss the chopped pecans in the dry ingredients and set this aside.
In the bowl with the zucchini add brown sugar, granulated sugar, coconut oil, vanilla, and thickened flax mixture and stir to combine well until it appears liquidy.
Add the wet ingredients to the dry ingredients and stir to combine well so no dry ingredients are visible.
Add to a lined loaf pan. Bake for 55 minutes or until a toothpick comes out clean from the center. Allow the bread loaf to cool in the pan on a wire rack for 15 minutes. Then lift the sides of the parchment paper to remove the loaf and continue to cool on a wire rack before slicing and serving. Store loosly covered at room temperature or in the frige.
