Seed Starter Kits: A Buyer’s Guide
A seed starter kit, as the name suggests, is a kit that comes equipped with components that are needed to start plants from seeds. There are many benefits of using a seed starter kit. For one thing, if you live in a cold climate, these kits allow for better timing. There are only so many days between spring’s final frost and autumn’s first frost, which gives you a very limited window of time to grow plants outside to full maturity.
In order to expand your growing season and reap more of what you sow, a seed starter get can help you get around a short growing season, as you’ll be able to plant your seeds indoors, which means that you’ll be able to get a jump start on the main growing season in your region.
Secondly, you’ll be able to save a good bit of money when you plant a garden from seeds that you started indoors. Packages of seeds are much less expensive than already established plants; and nowadays, the cost of plants is constantly rising, so you could save a substantial amount of money, especially if you intend on growing certain types of plants or you are planning a larger garden.
Thirdly, while you might be able to find a decent selection of starter plants at your local nursery, you’re limited to the species that they carry. If you’re looking for specific types of plants, you may not be able to find them at your garden store, but if you plant seeds, you’ll be able to grow a much larger variety of flowers, veggies, and/or fruits. Lastly, when you grow your plants indoors in a seed starter kit, you’ll be able to experience the sheer happiness, and sense of pride and accomplishment when you see the seeds you planted and the accompanying garden flourish.
Needless to say, no matter what climate you live in and what type of plants you’re planning on growing, there are a great many benefits associated with using a seed starter kit. If you have decided that you want to take advantage of these benefits, however, when you go shopping for a seed starter kit, you’re going to find that there are so many different options to choose from.
While choice is certainly a good thing, with such a wide variety of seed starter kits, trying to decide which one to go with can seem like a daunting task.
As you can see, there are several different seed starter kits, and our list features (in our opinion), the highest quality, most reliable options. But even though we have narrowed down the options to a handful of a few high-quality models, it can still be a bit overwhelming to figure out which one will best suit your needs.
With that said, to help you further narrow down the choices and zero in on the right model for you, taking some key factors into consideration before you start shopping is definitely recommended. In this part of our guide, we share the most notable factors that you’ll want to consider to help you choose the perfect starter kit for your seeds and establish a healthy garden that will produce wonderful results.
First and foremost, you’ll want to consider the function of the starter kit. By function, we mean the type of kit, and there are a few different options to consider, including:
- Portable natural greenhouse-style. This type of starter kit features a base that’s sectioned off into different pods, so to speak, and each pod accommodates a small amount of soil that will hold seeds for individual plants. A dome is attached to the top, which helps to produce heat and regulate water, creating a mini-greenhouse, of sorts. This style is usually the most affordable.
- Hanging starter kits. The perfect example of this type of starter kit is our pick for the best overall kit, the Window Garden Double Veg Ledge Shelf Seed Starting Kit Bundle. It’s similar to a portable natural greenhouse-style kit, in that it functions like a greenhouse; however, it is designed to attach to a window and lacks a dome. Instead, the sunlight that comes into the window that the kit is attached to generates the heat and regulates moisture.
- Heat lamp and heating mat kits. These are the highest end kits and they’re an ideal choice if you’re planning on starting your seeds in an area that’s lacking sunlight or in a cold area. These models feature heat lamps, which are designed to sit over a dome, and a heating mat, which sits underneath the base of the kit. The lamp functions as artificial sun, delivering the UV rays that seeds need to grow, and the heat mat provides the roots with the ideal amount of heat. These starter kits are designed to speed up the rate of propagation; however, they do tend to be pricier.
Once you decide on the function or style, the next thing you’ll want to consider when you’re shopping for a seed starter kit is the cells. The cells refer to the sections on the base of the tray that the seeds are grown in.
You’ll want to consider the number of cells, as well as the size of the cells. Obviously, the more cells, the more plants you’ll be able to propagate. In regard to size, larger plants require more space in order to ensure that they can develop strong, healthy roots. Typically, the larger the cells, the fewer plants you’ll be able to grow.
Think about the type of plants that you want to grow, as the species will indicate how much room you’ll need and what size cells will best suit your needs.
It’s also a good idea to consider the durability of the seed starter kit. Some kits are made of cheap materials, which mean they usually cost less; however, they tend to be flimsy and they don’t last long.
If you want something that you will be able to use for several seasons, you’ll want to opt for more durable materials, as they will last longer. While seed starter kits that are constructed of more durable materials do tend to cost more initially, in the long run, they’ll actually end up saving you money, as you won’t need to replenish them as frequently.
Ease of Use
Lastly, you’re going to want to consider the ease of use. The easier the seed starter kit is to use, the more enjoyable the process will be. To simplify the process, some kits come with growing medium, which is usually formed into the shape of a pod that slips right into the cells.
Often, they are specially designed to promote proper oxygenation and nutrient absorption. These kits do tend to be easier, as you don’t need to buy your own growing medium; however, the price is usually higher for these kits and eventually, you will need to purchase additional growing medium.
Seed Starter Kit FAQs
How do I know if I should use a seed starter kit?
Consider the type of plants you want to grow, as well as your climate. Generally speaking, seed starter kits are ideal for those who live in colder climates, as the outdoor growing season is shorter. Additionally, there are certain species of plants that do better when they’re started from seeds indoors (research the type of plants you want to grow). Regardless of the species of plants and your growing season, a seed starter kit is beneficial for anyone, as they do promote faster and better propagation, they can help you save money, and they’re enjoyable to use.
Are seed starter kits easy to use?
Yes, they’re actually quite simple to use. Just fill the cells with a growing medium, plant your seeds, follow the instructions that come with your kit, and watch your seeds take root, sprout, and blossom.
With a seed starter kit, you’ll be able to start a robust garden full of healthy flowers and/or produce. With the information presented in this comprehensive guide, you should have no trouble selecting the perfect kit to suit your unique needs.
