288!?! 12x24 cells? More than twice 128?
Now I'm dizzy ... and I gotta try one! Fortunately I found a Steuber's Distributing within a drivable distance, and they sell singletons. That's where I found my extra-deep 50-cell plug trays. WANT DEEP!
I like Groove Tray. reminds me of the '70s ...
>> Where do you get the shorter trays?
I don't think I've seen those. I usually shop online at Greenhouse Mega-store and Growers Supply.

Indoors, I make smaller trays out of cut-down cardboard boxes lined with heavy plastic bag film.
