Jiffy Seed Starter Greenhouse with Jiffy-Strips — 50mm Peat Strips 50 Cells

Complete Seed Starting in One Kit — 50 Peat Strip Cells, Watertight Tray, and Humidity Dome Included

Successful seed starting requires three things: a growing medium that holds moisture and supports root development, a watertight tray that prevents mess and allows bottom-watering, and a humidity dome that maintains the high-moisture microclimate seeds need to germinate reliably. The Jiffy Seed Starter Greenhouse includes all three in a single ready-to-use kit — 50 peat strip cells at 50mm, a watertight base tray, and a clear humidity dome — so growers can start seeds immediately without sourcing components separately.

Jiffy-Strips are made from compressed peat that expands when moistened, providing a lightweight, well-aerated growing medium with excellent moisture retention. At transplant time, Jiffy-Strips are designed to be broken apart at the perforations between cells, separating individual plants without bare-rooting or disturbing the established root system. The peat cell walls break down in the soil after transplanting, eliminating the transplant shock associated with pulling seedlings from rigid plastic trays and making root transition faster and more complete.

The watertight base tray supports bottom-watering practices that deliver moisture directly to the root zone from below, reducing the risk of damping-off from overhead watering. The clear dome seals in humidity to accelerate germination and can be vented or removed progressively during hardening-off. The complete kit is sized for 50 seeds or cuttings per use and is available in cases of 8 for commercial and production use.

Key Features & Benefits

• 50 Cells Per Kit — Complete 50mm Peat Strip Set — Provides 50 individual growing cells at 50mm size, suitable for a wide range of vegetables, herbs, flowers, and ornamentals from germination to transplant-ready stage.
• Biodegradable Jiffy-Strips for Mess-Free Transplanting — Peat strips break apart at cell perforations at transplant, separating plants cleanly without disturbing roots. The peat walls break down in soil after planting, promoting faster root establishment than rigid plastic cell trays.
• Watertight Base Tray for Bottom-Watering — The sealed base tray holds water for bottom-watering practices that deliver moisture directly to root zones, reducing surface moisture that promotes damping-off and fungal issues in seedling trays.
• Clear Humidity Dome Included — Seals in moisture during germination for faster, more uniform seed emergence, then vents during hardening-off to acclimate seedlings to ambient growing conditions before transplanting.
• All-in-One Kit — No Separate Component Purchasing — Cells, tray, and dome are included in one package, eliminating the need to source matching components from multiple suppliers and ensuring proper fit between all three elements.
• Suitable for Vegetables, Herbs, Flowers, and Ornamentals — The 50mm cell size is appropriate for a broad range of seed starting applications across food crops, cut flowers, bedding plants, and ornamental starts.

Who Should Use the Jiffy Seed Starter Greenhouse

The Jiffy Seed Starter Greenhouse is the ideal choice for home gardeners, hobby growers, indoor growing enthusiasts, and small-scale nursery operations who want a complete, reliable seed starting system without sourcing components separately. It is particularly well-suited for growers who value easy, mess-free transplanting — the biodegradable Jiffy-Strip cells remove the need for bare-rooting at transplant time, which is the single most common cause of transplant stress and failure in vegetable and ornamental production. The kit's 50-cell capacity makes it practical for both single-variety starts and mixed-variety propagation trays.

Frequently Asked Questions

How do I properly moisten Jiffy peat strips before seeding?

Pour warm water into the base tray or directly over the peat strips until they are evenly moist throughout — not saturated. Peat can be slow to absorb water initially; allow 5-10 minutes for complete uptake before adding more water to avoid oversaturation. The strips should feel uniformly moist and slightly spongy, not dripping wet. Drain any standing water from the tray before placing seeds.

Can Jiffy-Strip cells be transplanted directly into soil without removing the peat?

Yes — and this is one of the key advantages of Jiffy-Strips over rigid plastic cell trays. Individual cells are broken apart at the perforations, and the plant plus peat cell is transplanted directly into the prepared soil or growing medium. The peat walls decompose in the soil within a few weeks, allowing roots to expand freely without any barrier. For best results, ensure the top of the peat cell is at or below the soil surface after transplanting to prevent the peat from wicking moisture away from the root zone.

What is the difference between Jiffy peat strips and peat pellets?

Jiffy-Strips are pre-formed peat cells in a strip format — connected cells that can be broken apart at transplant. Jiffy peat pellets are individual compressed discs that expand in water and have a netting casing around the peat. Both are biodegradable and transplant without bare-rooting, but strips tend to be better suited for high-volume production where tray-format organization is important, while pellets offer flexibility for planting into different tray configurations. The Jiffy Seed Starter Greenhouse kit uses the strip format for efficient tray-based production.

How many times can the tray and dome be reused?

The watertight base tray and clear humidity dome are designed for reuse across multiple propagation cycles. Clean both components between uses with a diluted bleach solution (1:9 bleach to water ratio) or a registered greenhouse sanitizer, rinse thoroughly, and dry before restocking with new Jiffy-Strip cells. The peat strip cells are single-use and are replaced each cycle. Replacement Jiffy-Strip refills are available separately.
