FAQs
General(8)
What does a humidity dome do?

It keeps warmth and moisture around your seeds, helping them sprout faster and more evenly.

Why are there little vents on top?

The vents let you control how much air gets in, so your plants don't get too wet or too dry.

Should I leave the vents open or closed?

Start with them closed to keep it nice and humid. Open them a little once you see green sprouts.

Can I use this for any seeds?

Yes! It works great for veggies, herbs, and flowers — especially seeds that like warmth, like tomatoes and peppers.

How tall is the dome?

It's 14” tall, enough for your little plants to grow before you move them outside or into bigger pots.

When do I take the dome off?

Once most of your seedlings are growing and have little leaves, you can remove the dome.

Will this fit my seed tray?

Yes, it fits the regular-size trays (10x10,10x20) most seed kits use.

How do I clean the dome?

Just wash it with warm, soapy water after each use to keep your plants healthy.
