Gardzen 5-Set Seed Starter Tray Kits with Vented Domes (200 Cells)
Gardzen's 5-Set seed starter tray kits with vented domes and 200 cells for starting large batches indoors.
MIXC 10 Packs Seed Starter Tray Kit with Humidity Dome (120 Cells)
MIXC's 10 Packs seed starter tray kit with humidity domes and 120 cells for starting many seedlings.
Seed starting trays let you raise a whole flat of seedlings on a windowsill or a small table, then move the strongest ones out to your balcony pots when the weather turns. Starting from seed is far cheaper than buying plants, and it opens up varieties you will never find at a garden center. For tight spaces, look at cell count and footprint so the tray fits your sill, and check whether it includes a drip tray and a clear humidity dome. Sturdier reusable trays outlast the flimsy ones that crack after a season, and clear domes speed up germination on a cool indoor ledge.
