What can I grow in the 24 Cell Adjustable Humidity Dome & Propagation Tray?
It’s ideal for starting herbs, vegetables, flowers, microgreens, and even soft cuttings. The controlled humidity makes germination and rooting easier, especially for beginners or indoor growers.
What comes with the 24 Cell Propagation Tray kit?
The kit includes a solid base tray, a 24-cell insert, and a clear dome lid with adjustable ventilation. It’s sturdy, leak-resistant, and easy to move even when full.
How do I use the adjustable vent and lid?
Keep vents mostly closed during germination to hold humidity. Once seedlings sprout, open the vents gradually, then remove the lid fully after a few days. Don’t keep it sealed too long—ventilation prevents mold and weak growth.
Do I need grow lights or can I use a windowsill?
Grow lights are ideal—especially in winter or low-light rooms. A bright windowsill can work, but watch for leggy growth or overheating if sun hits the dome directly.
Should I use a heat mat or place the tray outdoors?
Heat mats help warm-season seeds germinate faster, especially in cool rooms. Outdoors is fine if sheltered from wind, heavy rain, and harsh sun that could overheat the dome.
What soil or growing media should I use?
Use a light, sterile seed-raising mix. Coco coir, foam plugs, rockwool cubes, or biodegradable pots can work too, if they fit. Avoid compost-heavy mixes indoors—they often grow mold.
How should I water the tray, and does it drain?
Bottom watering is best—pour water into the base and let it wick up. Avoid leaving standing water. The tray is solid, so tip out any excess after a soak to prevent root rot or gnats.
How many seeds should I plant per cell?
Usually 1–2 per cell. Thin to the strongest seedling if both germinate. Plant depth should be about 2–3 times the seed’s thickness, or surface-sown if the packet says so.
Why are my seedlings leggy, yellow, or drooping?
These are signs of poor light, overwatering, or nutrient deficiency. Use grow lights, add airflow with a small fan, and start feeding lightly once true leaves appear.
How do I prevent mold, fungus gnats, or damping off?
Improve airflow, avoid overwatering, bottom-water when possible, and remove the lid once sprouts emerge. Yellow sticky traps and clean seed mix also help reduce issues.
When should I transplant seedlings?
Once they have 1–2 sets of true leaves and the roots hold together. Don’t wait for roots to circle or for cells to dry out rapidly—both signs of root-binding.
Do I need to harden off seedlings before planting outside?
Yes—gradually expose them to sun and wind over 5–7 days. Start in a shaded, sheltered spot, then increase outdoor time daily. It prevents transplant shock and sunburn.
Is the tray reusable and how do I clean it?
Yes—just wash with warm soapy water, rinse, and dry. If you’ve had mold or disease issues, sanitise with a mild disinfectant before reuse. Fresh seed mix is always recommended.
Can I label individual cells in the tray?
Absolutely—especially if starting multiple varieties. Use plant tags or waterproof stickers. Your future self will thank you.
