HIKO Tray (40 cells / 93ml per cell)

What is the HIKO Tray (40 cells) used for?

This 40-cell tray is designed for raising seedlings, cuttings, and small divisions with strong root plugs. It’s ideal for natives, forestry plants, and ornamentals you want to hold a bit longer before potting up or planting out.

How big is the HIKO Tray (40 cells) and how much does each cell hold?

The tray measures about 350mm × 215mm × 90mm, with 40 cells arranged in an 8×5 grid. Each cell holds around 93ml of media—enough to grow a solid plug without root binding too fast.

What is the tray made of, and is it reusable?

Made from rigid polypropylene, the tray is built for durability and reuse. It’s much tougher than thin seed trays. With proper care, it handles repeated cycles and storage. Keep it shaded when not in use to reduce UV wear.

Does the HIKO Tray help prevent root spiraling and transplant shock?

Yes. The cell shape promotes downward root growth and branching, not circling. That structure helps plants establish faster when potted up, reducing transplant stress.

When and how should I transplant from the HIKO Tray?

Transplant when the root plug holds together, has visible white roots, and the plant has strong top growth. Push plugs out gently from the base—don’t pull from the stem. A blunt tool helps for faster work.

Can I water from the top or bottom with this tray?

Both work. Top watering is fine if done gently and evenly. Bottom watering is easy—just sit the tray in a shallow reservoir briefly, then let it drain. Avoid letting it sit in runoff long term.

What growing media works best in the HIKO Tray?

Use a light, airy seed-raising mix for germination, or a perlite-blend for cuttings. Coco, peat, and perlite-based mixes are all compatible—just manage moisture. Always pre-wet before filling for even hydration.

Can I use the HIKO Tray with humidity domes or heat mats?

Yes—just match the dome footprint to the tray size. It also works well on heat mats, under lights, or in hydro tents. Monitor moisture more closely when using bottom heat.

Can I use this tray outdoors or for hardening off?

Yes—it’s suitable for outdoor use, but cells can dry quickly in sun and wind. Use shade cloth and check moisture often. It’s also great for hardening off batches before transplanting.

What’s the best way to clean and sanitise the tray between uses?

Empty the tray, scrub with warm water, and sanitise if needed. Let it dry fully before reuse or storage. This helps prevent algae, fungus gnats, and pathogen carryover between crops.

Is the HIKO Tray good for beginners?

Yes—it simplifies seedling care and makes it easier to monitor moisture, root development, and growth consistency. Each plant has its own cell, so mistakes affect fewer plants.

Can I use this tray with automation like misting or drip irrigation?

Absolutely. The consistent drainage and cell layout work well with mist benches or light drip systems. Just monitor salt buildup with fertigation and flush if needed.

Can I use soil blocks, rockwool, or plugs in the tray?

Sometimes. If the blocks or plugs fit the cells snugly and drain well, go ahead. It can also serve as a carry tray for other propagation formats—just match the spacing.

What are common mistakes with the HIKO Tray?

Overwatering is the most common—small cells don’t need heavy soaking. Another is waiting too long to pot up; once roots fill the plug, growth can stall. Stay on top of watering and timing for best results.

How do I get the best results quickly?

Use clean trays, fill with pre-wet airy mix, water evenly, and give seedlings gentle airflow. Transplant as soon as roots are well formed—don’t let them sit root-bound.
