Take a tour of several indoor garden rooms full of clones growing on tables. The irrigation is automatic and drains into a reservoir below the tables.
See another big garden room (24 600w lights) full of Train Wreck. This video is a bit different and worth watching as the growers harvest every 42 days! The growers remove and replant the garden in one day. They are able to grow several more crops every year because of the short harvest dates.
