The versatile size of these sturdy 6-packs is ideal for single seeds of cucumber or pumpkin, multi-sowing beet root, onion and radish, and for potting up tiny seedlings of basil, celery, celeriac and parsley. For my home garden, it is efficient to be able to combine multiple different veg and flowers in one flat in the greenhouse, take a 6-pack of seedlings out to their garden bed when ready, and starting some other seeds in their place.
