Whether you are a novice or have prior experience growing plants from seed, choosing the best starter kit can be overwhelming. Seeds grown in a tremendous and protected ground with ideal soil will germinate quicker and develop into a healthier and hardier plant. So which options are the best to consider?

Buying guide of Best Seed Starter Kit

Guide to buy Seed Starter Kit

Buying a suitable seed starter kit on amazon can be daunting, especially now that there are several choices to choose from. Fortunately, some aspects can guide you choose the right one. These can be;


Most seed starter kits possess a dome, which is plastic-made. This dome can be perceived as a mini greenhouse. Therefore, the first thing you will want to consider is the dome size. Choose a large enough dome because some plants can outgrow before transplant.

Additionally, consider the dome with a vent. It is a great feature that helps control temperature and humidity. Some types can come with an adjustable opening that enables you to introduce the plants to the environment.

Number and Size of the Cell

The number and size of the cells are a great feature that needs consideration. Small plants need little space, while larger counterparts need enough space to enable healthy and strong roots. Ensure that the cell will be enough to hold the specific plant you want to grow.


Many kits are tailored to be multipurpose, and therefore, this does not imply their quality and durability are similar. Some are made using flimsy and cheap materials, which can be reused but not for a long time. Alternatively, there are kits made of robust and durable materials that are easily used in every season. Although such materials can cost more, they are worth investing in.

Growing Medium

The starter kit you want to purchase must indicate the growing medium. Some types can tolerate all the growing medium, but others will not. Some starter kits have a sterile medium appropriate for seed germination and growth of the plant. Picking a starter kit that comes with a growing medium means you have everything under control.


One of the challenging things experience by farmers is germinating seeds and seeing them thrive and grow. Usually, seedlings are susceptible and delicate to almost all disturbances. However, considering the best seed starter kit can be the ultimate solution. Just choose any of the plant seed starter kits mentioned here and allow your seeds to blossom solid and healthy.
