To use grid loop on a page instead of the standard Genesis loop.

genesis-grid-loop.php

//* Remove entry meta in entry footer and Genesis loop
remove_action( 'genesis_loop', 'genesis_do_loop' );
		
//* Add Genesis grid loop
add_action( 'genesis_loop', 'my_grid_loop_helper' );

//* Genesis grid loop
function my_grid_loop_helper() {

	if ( function_exists( 'genesis_grid_loop' ) ) {
		genesis_grid_loop( array(
			'features'		=> 0,
			'feature_image_size'	=> 0,
			'feature_content_limit'	=> 0,
			'grid_image_size'	=> 0,
			'grid_content_limit'	=> 250,
			'more'			=> __( '[Read more]', 'theme-prefix' ),
		) );
	} else {

		genesis_standard_loop();
