    This was a great tool to have


    Love every product from here!

    Good quality

    Exactly what I wanted. Good quality. Will be able to reuse in the future. Definitely recommend.


    I love! But the beginning was a mess for me. I’m sure it was user error.


    I got this and some seeds and the greenhouse is so cute and small. Great starter space for seedlings.

    how difficult are these seeds to grow?

    Houseplant seeds are generally trickier to grow than your more common garden seed varieties- they require a specific setup and more time to sprout. You can find the difficulty for each seed variety specified under the "about the seeds" tab on each product page.

    We definitely recommend following the setups outlined in our seed guide here, and you can find further details in our blog!

    how long does it take for the seeds to germinate?

    Houseplant seeds take longer than most seeds to germinate, the average time for germination is 2-3 weeks. If you're curious about the sprouting time for a specific seed variety, you can find that information in the "about the seeds" tab on each product page.

    how do I grow houseplant seeds?

    All of our orders come with a basic starter guide for you to follow, but our seed guide here goes in much more detail and also offers alternative seed starter methods.

    We also include additional planting tips specific to each seed variety under the "instructions" tab of each product page. If you need extra help, don't hesitate to reach out to us at!

    my seeds aren't germinating, what do I do?

    Houseplant seeds are tricky, and sometimes certain more difficult varieties can take some practice to finally get them to sprout!

    If you're having trouble with the seeds, you're not alone. Luckily there are ways to sometimes salvage seeds by adjusting the setup- this quiz can help diagnose any issues you may have with your setup and make suggestions for how to improve it.

    You can also email us at and we can help out! If the seeds still aren't germinating, we'll send out a replacement :)
