PlantBest Greenhouse Seed Starter Kit - 72-Cell Plastic

Complete 72-Cell Starter Greenhouse for First-Time and Repeat Seed Starters

Sourcing a tray, dome, and cell insert separately usually means guessing whether the pieces will actually fit together, and a mismatched set leaves gaps that let humidity escape. PlantBest's 72-Cell Greenhouse Seed Starter Kit ships as one matched system: a 72-cell plastic insert, a greenhouse tray sized to hold it, and a humidity dome that seals over both, individually shrink-wrapped for retail-ready presentation.

Printed growing instructions are included in the box, so the kit works as a first seed-starting setup as easily as it works as a repeat-season staple for a grower who already knows the routine.

Key Features & Benefits

• 72-cell plastic insert — high cell count starts a full round of seedlings in a single tray, making efficient use of bench or windowsill space.
• Matched tray and dome — engineered to fit together with no gaps, so humidity stays where the seedlings need it instead of leaking out at the edges.
• Growing instructions included — gives a first-time starter a reference for timing and care without needing to look anything up separately.
• Individually shrink-wrapped — keeps the kit clean and intact in storage or on a retail shelf until it's opened.

Who Should Use This Kit

This kit fits home gardeners starting vegetables, herbs, and flowers from seed for the first time as well as returning growers who want a complete, no-assembly-required setup each season.

About PlantBest

PlantBest builds propagation hardware too. That runs alongside its coir media. It targets home gardeners and commercial growers. Both groups start plants from seed or cutting. Coir runs through the line as a substrate. It's a peat-free option throughout. The brand also sells trays, domes, and heat mats. Those support germination and early growth stages.

Frequently Asked Questions

What is included in the kit?

The kit includes a 72-cell plastic insert, a matched greenhouse tray, a humidity dome, and printed growing instructions. Everything ships shrink-wrapped as one retail-ready unit.

Is this kit suitable for someone who has never started seeds indoors?

Yes, the included growing instructions cover timing and basic care, which is enough to get a first-time grower through germination and early seedling growth. Returning growers can skip the instructions and go straight to sowing.

How do I get replacement cell inserts for this kit later?

PlantBest sells a 72-cell refill pack sized for the same tray and dome, so the tray and dome don't need replacing each season. Only the cell inserts wear out with repeated use.

What growing medium should I use in the 72-cell insert?

A fine-textured seed-starting mix works best, since heavier potting soils can compact in small cells and restrict root development. Avoid coarse bark-heavy mixes for the same reason.
