Johnsons MicroGreens Growing Tray Starter Kit 5 "Not lidded" Rose Luckman 21 May 2017 This is described as lidded, but there is no lid - at least mine didn't have one, but I don't think it really needs a lid. The clear plastic tray goes underneath the seed trays to hold water and for the roots to grow into. Otherwise very pleased with it, it's just what I needed, and I may order some more. I've only tried the rocket seeds so far, but I've had no problem with them. They have nearly all germinated, close to 100% I'd say.
