dan apparatus on "[Plugin: WooCommerce - excelling eCommerce] Reducing number of products only on shop page?"

I just got some helpful and speedy assistance on here, so I know I'm pushing my luck to see if I can get another question answered, but here goes.

I'm trying to find a filter to reduce the number of products on ONLY the shop home page. I am familiar with this code:

add_filter( 'loop_shop_per_page', create_function( '$cols', 'return 36;' ), 20 );

to edit the amount of products per page (as you can see I have edited already) but I am still looking for a way to reduce the number of new products displayed when a customer first enters the store, while still having them all collected in a larger group on each proceeding category page.

Make sense?
Any thoughts?

Thanks!
