I have around 125 seedlings up and three more 72 cells trays going down March 1st(two trays annuum's and one tray tomatoes). I am racking my brain trying to figure out how to carry these outside to harden them off every single day when the time comes. I need something that can carry as many 16 ounce cups as possible, the more the better. I wish I had a garage and and rolling racks but I have neither a garage or rolling racks. Any suggestions? I had eyed some flat type storage containers but they were too much money per container and would only hold a limited number of cups. I own no power tools so custom builds would be out. I have been trying to come up with ideas for about a week now with no luck, so I am open to all ideas.
