ULF 7X17 Stainless Trays from Costco!

[Peter Gomena]

The mortar trays I'm referring to are about 20x24", maybe a little narrower.

Interesting. I use these for starting seeds but they're the right size. Not super stiff but should be strong enough. important thing is they're cheap !

Fred, I have used those seed trays. They're cheap and the right size but they are too fragile. The material is so thin that the corners develop crack and begin to leak.

I have been using these for 4 years now and they are perfect:

Another source for very large trays are farm supply stores like Theisen's, Farm & Fleet, etc. They have a lot of containers that can be modified for ULF type work.

yeah, they are very light weight but seedlings aren't as heavy as a tray full of developer and fixer. Those trays in you rink perfect, will have to see if they're available up here. thanks John !

I have two types of seed starting trays. One set is black and a little fragile, although usable. These were the first ones I bought.
The other is at least twice as thick, very smooth green plastic and work beautifully. When loaded I can pick up one corner without feeling like the tray is going to break. If I pick up by the middle of the end, they do not flex.

For 7x17 I´m using this IKEA STÖDJA cutlery tray. Cut of right part, left long side is exactly for 7x17" sheet.
