Flow Trays provide sub-irrigation for plant material which are difficult to water overhead and will hold a single Cone-tainers tray.
Flow Trays measures 27"L x 15.2"W x 4"H and are made of sunlight resistant plastic that is very durable.
Cone-tainers Tray and cells are sold separately.
It's ok.. the plastic Brittle and over time will crack. Needed to be made from a plastic that has a little more flexibility.
These are not as heavy as I thought they'd be. They're about the only choice for a tray if you're using Cone-tainers so I am keeping them. They are heavier than a standard tray, I just hope they last in my greenhouse.
