Gardzen 72-Cell Seed Starter Trays 10-Pack — 1.57" Deep Cells, Durable Stackable Plug Trays for Strong Taproots

Gardzen 10 pack of 72-cell seed starter trays gives you deep, durable cells with reliable drainage so seedlings develop strong, transplant-ready root balls.

These 72-cell plug trays are designed for hobby and small-scale growers who need to start large numbers of seedlings without sacrificing root quality. Each cell measures about 1.57 inches deep to support taproot development for brassicas, lettuce, herbs and other common garden plants. Constructed from rigid, warp-resistant plastic, the trays resist bending when filled with moist potting mix and stack neatly for storage.

How do these trays encourage healthier roots?

The extra depth supports taproot growth so young plants form firmer root balls that travel through transplanting with less shock. Each cell includes a drainage hole that prevents water from pooling at the bottom, keeping roots aerated and reducing the risk of rot.

• 1.57" deep cells for stronger taproot development
• Individual cells form compact root balls for easier transplanting
• Drainage holes remove excess water quickly
• Cell shape promotes even root distribution

Will these trays hold up under repeated use?

Yes — the trays are made from professional-grade rigid plastic formulated to resist warping when packed with moist growing medium. They keep their shape when stacked and can withstand the routine handling common in propagation tasks.

• Durable material maintains structure with wet soil
• Stackable design saves storage space
• Reusable for multiple growing seasons with basic care
• Edges and cell walls resist cracking under pressure

How do I water and manage seedlings in these 72-cell trays?

These trays work with both top and bottom watering methods; drain holes let excess water escape and allow for bottom soaking when paired with a drip or 1020 tray. Bottom watering encourages roots to grow downward and reduces surface mold and compaction.

• Compatible with standard 10x20" drip trays for bottom watering
• Drainage holes make overhead watering safe and effective
• Use a light, well-draining seed mix to avoid waterlogging
• Easy to lift and move without disturbing individual plugs

How many different plants can I start and what fits best?

With 72 cells per tray these are ideal for starting large numbers of small-to-medium seedlings such as brassicas, lettuces, and herbs. The cell size balances plant count and individual space so each seedling receives enough soil to develop robust roots before transplant.

• Great for broccoli, cabbage, kale, and lettuce seedlings
• Perfect for herbs and ornamental annuals
• Use one cell per seed for single varieties or multiple for larger transplants
• Ten trays in the pack let you start hundreds of seedlings at once

Who is this for? Growers who need an economical, repeatable propagation system will appreciate this Gardzen 10-pack of 72-cell trays. It suits backyard vegetable growers, community gardeners, nursery staff, and greenhouse hobbyists who want consistent root development, reliable drainage, and sturdy trays that endure frequent use.
