FAQs

What is the advantage of bottom watering with this kit?

Bottom watering allows the soil to absorb just the right amount of moisture through the drainage holes, reducing the risk of damping-off and keeping seedlings healthier. Simply add water to the base tray and empty excess after 20–30 minutes.

Do the humidity domes seal tightly?

No, they are not airtight. The domes reduce moisture loss while the adjustable vent dial lets you control airflow and humidity, helping prevent mold and ensuring seedlings adapt gradually after sprouting.

Can I reuse these trays and domes?

Yes. After each season, wash with warm soapy water and disinfect with a mild bleach solution (10%) before reusing. Proper care ensures multiple growing seasons.

Can I use a heat mat and grow lights with this kit?

Absolutely. Heat mats help stabilize soil temperature for faster germination, while grow lights provide strong, consistent light for compact, healthy seedlings.
