3 seed tray inserts

Three inserts, one job: turning a single seed tray into a properly organised nursery for dozens of seedlings at once. Slot them in, sow your rows, and watch a whole tray fill with tidy, evenly-spaced plants that are easy to check on and easier still to lift out when the time comes. It's unglamorous, essential kit — the sort of thing that quietly makes every sowing session go smoother.
