Sorry i didnt mean to infer that you are the ones in the video. They are the Mendo Dope Boys. Been around the triangle for a few years. Its complete overkill. 500 gal is overkill.
They look really cool but you cant have all your plants like that. It creates too much work. I grew a 10-11 ft Willie Nelson in a 60 gal. Biggest pain in the ass I ever grew.
