Now USA Made! 2 ft x 4 ft (45½" x 25½" x 3½") Rack Tray is designed to fit standard chrome wire shelving that is 18 in. wide. This allows the 3-inch drainage channels to be lower than the growing surface for optimal drainage.
Utilizing baker's racks for vertical propagation allows you to increase your production by more than 300% without sacrificing additional square footage.
The 2 ft x 4 ft rack is perfect for large-scale microgreen or commercial propagators looking to maximize their production. Specifically designed features allow this tray to sit flat on shelving with a trough that hangs slightly over the edge.
The trough reduces standing water.
This rack tray will fit four 10 x 20 inch propagation trays.

Hi, What are the measurements on the inside bottom? Thanks.
Unfortunately I went with 48w X 18w X 72h shelving racks. Are the flood trays strong enough to have 3" overhang on front and back of wire shelving while watering?
Yes this shouldn't be an issue to have the rack trays over hang by 3".
Hi there, I love the shallow micro trays I got from you last year, and would like to start bottom watering with the 2'X4' rack trays. Are you able to ship them to Canada? I don't see them on the Amazon store. Also, do you drill holes in the tray to connect hoses and pumps for automated systems? Thanks!
Thank you! We currently aren't shipping those to Canada. We tried but things end up cracked or chipped too often no matter how we pack it. Something about crossing the border! Hopefully next year timetime we'll have a local retail partner in Canada for products like this. And yes, there is a flat area to drill holes for your plumbing.
Is there a drain fitting hole in the edge somewhere? Do you sell a kit to install a drain in the edge?
There is a plumbing space for you to drill your own hole. Hole requirements vary depending on use, so a hole saw will help you create the hole you desire. We recommend uni-seals as an easy, leak-proof solution.
what is the depth on the main (non overhang) part of the tray?
Will this work well with shallow mircogreens
Sure does! We recommend using hemp or some other mat as the media in a combination of a flood & drain.
You say it will fit a rack 48W X 24D. but the usalble space is only 46"wide X 24" because of the round legs (1" X 2) What is the out side measurements of the flood tray?
Thank You as always
The outside dimensions are 45 1/2" x 25 1/4" x 4"
Will 10x20 flats rest on the lip suspended, or sit down in the tray with the bottom resting on the inner bottom surface? Ill be using this for bottom watering shallow microgreen trays, so it won't work well if they are suspended by the top lip, eh?
The trays will rest on the surface and the water will come in through the drain holes as you bottom water.
does this come with the bulk head for supply and return?
