Jiffy Seed Starting Tomato & Vegetable Greenhouse - 36-Cell, 50mm Pellets

50mm Peat Pellet Seed Starting Kit for Tomatoes & Vegetables, 36-Cell

Tomatoes, peppers, and other vining vegetables develop bigger root systems early than herbs and flowers do, and a standard 36mm or 42mm pellet can leave them root-bound before they're even ready to go outside. Jiffy's 50mm pellet kits scale the pellet size up for exactly these crops, giving roots more room to establish before transplant.

The 36-cell size, in an 11in x 11in x 4.25in tray, is built for growers starting a full batch of tomato, pepper, or other vegetable seedlings at once, whether for a home garden or a small market planting.

Key Features & Benefits

• 50mm biodegradable peat pellets — Jiffy's largest pellet size, sized for tomatoes, peppers, and other vigorous seedlings.
• Watertight tray sized for 50mm pellets — supports bottom-watering a full tray of the larger vegetable-scale pellets.
• Included humidity dome — keeps warmth and moisture locked in above the pellets while seeds germinate.
• Netting that dissolves at transplant — set the whole pellet into soil or a bigger pot without disturbing the roots inside.

Who Should Use This

This fits home gardeners and hobbyist growers starting tomatoes, peppers, and other larger-rooted vegetable seedlings indoors that need more root room than a standard herb or flower pellet provides.

About Jiffy

Jiffy, the seed-starting brand under Green Garden Products, is best known for the Jiffypot's direct-transplant design. These 50mm kits apply the same expand-with-water, transplant-with-the-seedling approach at a larger pellet size built for vegetable crops.

Frequently Asked Questions

How do I use this greenhouse kit

Set the pellets into the tray, add warm water, and let them fully expand before sowing seeds or setting transplants into the top of each pellet. Keep the humidity dome on until seedlings emerge, then remove it gradually.

When should larger vegetable seedlings be moved out of the tray

Move tomato and pepper seedlings to larger containers once roots start showing through the pellet's netting, typically a few weeks after germination. Waiting too long in the pellet alone can slow growth as roots run out of room.

Why use a 50mm pellet instead of a smaller one

Tomatoes, peppers, and other vining vegetables put on root mass faster than herbs and flowers, and the extra pellet volume gives those roots more room before the plant needs potting up. Smaller 36mm and 42mm pellets suit lighter-rooted crops instead.

Can I transplant the pellet directly into soil

Yes, the biodegradable netting breaks down in moist soil on its own. A whole pellet moves into the ground or a bigger container right along with the seedling, leaving roots undisturbed.
