What is the Humidity Dome & Propagation Tray used for?
It’s a versatile system for starting seeds, rooting cuttings, growing microgreens, and transporting punnets. The optional lid creates a mini greenhouse effect, helping maintain humidity for faster, more consistent germination—great for both beginners and experienced growers.
What’s included with the kit, and what’s the difference between options?
The “Seedling & Catch Tray” includes a solid base and grated tray. The “Complete With Lid” option adds a clear humidity dome. The grated tray supports airflow and drainage, while the base tray catches runoff. The lid’s drip design reduces water pooling on seedlings.
What size is the tray and what fits inside?
The tray footprint is 350 × 295 mm—perfect for standard seedling punnets, small pots, tubes, or even plug trays. Rockwool cubes, coco plugs, and cell inserts can also fit, as long as they match the footprint.
How should I use the dome lid for best results?
Start with the lid on to hold humidity, then open vents (or crack the lid) once seeds sprout. Remove fully after most germination to improve airflow. Avoid leaving the lid sealed too long, especially in direct sun, to prevent overheating and mold.
What’s the best way to water seedlings using this tray?
Bottom watering is clean and effective. Pour water into the base tray, let punnets wick it up, then tip out excess. Avoid standing water to reduce mold and fungus gnats. Top misting is fine for tiny seeds at sowing.
Which soil or growing media should I use?
Use a light, fine seed-raising mix for best results. Coco coir works well but needs feeding after true leaves appear. Compost-heavy mixes can grow mold indoors. Always start with clean trays and fresh media to avoid issues.
Do I need grow lights or can I use sunlight?
Grow lights are best for strong indoor seedlings. Windowsills can work, but many seedlings get leggy without enough light. LED grow lights are fine—just leave space for the dome and avoid overheating by keeping some airflow.
Why are my seedlings looking unhealthy?
Yellowing often means overwatering or nutrient deficiency. Drooping may signal excess heat or poor airflow. White fuzz or mold indicates high humidity and low ventilation—open vents, reduce watering, and use a fan to improve conditions.
When should I start feeding seedlings?
Once true leaves appear—the first set that resembles the adult plant—start with a gentle, diluted feed. Most seed-raising mixes are low-nutrient by design, so light feeding supports stronger growth.
When should I transplant seedlings and how do I harden them off?
Transplant when seedlings have true leaves and roots hold the plug together. To harden off, gradually expose them to outdoor sun and wind over several days. Start with shaded conditions to avoid transplant shock.
Can I reuse the tray after each season?
Yes—wash with warm soapy water and rinse well. For disease prevention, sanitise with a mild disinfectant and let it dry fully before reuse. Avoid dishwashers, as heat can warp plastic components.
How does the Taglock system work for plant labeling?
The Taglock system lets you clip compatible tags to the tray for clear batch labeling. You can also add plant labels inside punnets. It’s especially helpful when growing multiple seed varieties at once.
Can I use this tray outdoors or in hot climates?
Yes, but always shelter it from harsh midday sun and heavy rain. In Australian conditions, the clear dome can trap too much heat—use bright shade or filtered light to avoid overheating seedlings.
Does this tray support capillary mats or soaking irrigation?
Yes—the solid base tray works well for bottom watering or placing capillary mats beneath your pots. It can help reduce watering frequency, but don’t allow constant sogginess, which can cause root issues.
