If you prefer germination to cloning, you need the best seed starter kit possible. This will help increase the germination rate - how many seeds take root - along with your efficiency - how quickly these seeds take root.
As you can imagine, getting more seeds sprouted in a quicker manner will help you get more plants to harvest quicker - making this a no brainer investment. We don’t have to convince you that these are worth the money, you already know!
But, while there are some really great options out there - there are just as many cheap, low quality setups that should be avoided at all costs.
That’s the tricky part - identifying which kit is best for you and your grow. What components do you need, and what do you not need? We’re going to break it all down for you today and make it simple - offering up our takes for the top germination kits on the market.
What Exactly Is A Seed Starter Kit?
Before we share our list of the best picks currently available online, we need to explain what a kit consists of.
Of course, the foundation of the entire kit is the humidity dome and the seedling tray. These two are non negotiable. However, we also like to see a few other products in the kit - a seedling light (typically LED or T5 tube) along with a heat mat.
While you can certainly grab these on your own, the very best of the best seed starting packs come with a pack of rooting plugs, too.
In essence, you should have everything you need to germinate seeds after purchasing a complete kit. You may not need every aspect of a kit - perhaps you already have a light, or a heat mat - but it doesn’t hurt to grab everything all at once!
Are These Truly Worth The Investment?
Can’t you just start your seeds using the good old fashioned paper towel method? Or even just plant some soaked seeds right in your grow media?
Sure - go ahead and try! You will likely be able to get something started using these tactics, but your germination rate is going to be low. You also may have to wait a couple weeks before anything really sprouts.
That’s the benefit in using germination kits - they drastically improve the two important aspects of the germination process: success rate (how many seeds turn into plants) and efficiency (how quickly a seed sprouts a taproot). Now - let’s get into our criteria for selecting the products you’ll see on this list.
Our Criteria For Selecting The Best Germination Kit
We work with only the best brands in the horticulture industry, ensuring the products we carry on our site are as good as it gets.
This holds true for not just our seed starting supplies - but everything we sell. First and foremost, we look at brand reputation. You’ll only see the best brands below, including household names like Super Sprouter, SunBlaster, Hydrofarm, and HBX.
We also listen to what our customers experience has been when using these products - many of the products you’ll find below have 5 star reviews!
Of course, the most important aspect to us is what’s included - the more products within the kit, the better equipped you’ll be to start your seeds. So without further ado, here are our favorites.
What Is The Best Seed Starter Kit Of 2021?
We’re going to share kits for every type of grower - starting with some affordable, low-volume seed starting options and work our way up to the more premium options.
Stay through to the end if you’re truly looking for the best - cuz that’s where it will be!
Hydrofarm Hot House Seed Starting Kit
Most of the kits we’re going to share on the list include a grow light - this one does not. If you already have a fluorescent light or small LED light on hand, you can save money and just grab the Hydrofarm Hot House Seed Starting Kit.
This kit comes equipped with a 72-cell tray, complemented by a 7” dome. This taller dome allows your sprouts to grow a bit taller before you transplant them into their next home after germination.
You also get a heat mat to help increase the temperature for your seedlings, along with some rooting gel to increase germination rate and efficiency.
While this is certainly the best budget friendly seed starting kit, that doesn’t mean it’s low quality. It has only 5 star reviews, and is a great option for hobbyists looking to get started for less!
SunBlaster Mini Greenhouse Kit
If you do need a light, and want some options in terms of how you configure that light, consider the SunBlaster Mini Greenhouse Kit.
What’s really cool about this option is that you can choose four different options:
- LED without Stand
- LED with Stand
- T5HO without Stand
- T5HO with Stand
No matter how your grow room is set up or what type of technology you want, you can configure this kit to work how you want it. Just like the Hydrofarm Hot House, this kit comes with a 7” dome to help your plants get rooted strong before you need to move them.
The one drawback to this kit is it doesn’t include seed starter plugs - you can just add these to your cart here at Hydrobuilder and get everything all at once!
Super Sprouter 50-Site Premium Seed Starter Kit
The best option for most growers is the Super Sprouter 50-Site Premium Seed Starter Kit. This is the first kit on this list that contains everything you need to sprout your seeds, and then some! This includes:
- Seedling Tray & Dome
- T5 Light & Timer
- Root Riot Cube Tray
- Heat Mat
- Clonex Rooting Solution
- Art Of Propagation Book
With all these products, you’re well on your way to increasing your germination rate and efficiency.
Featuring some of the best individual products on the market, this kit is certainly one of our favorites. Hobbyists and even some boutique growers will see a positive ROI quickly when investing their funds here.
Super Sprouter 100-Site Premium Seedling Starter Kit
If you love the last kit, but your germination process requires a bit higher volume, then the Super Sprouter 100-Site Seedling Starter Kit is for you.
This includes many of the same great products you just read about - but it also comes with a stand, and twice as many trays, domes, and rooting plugs to help you meet your quota.
If you’re a commercial grower, this is the best indoor seed starter kit currently available. For less than $170, you can start 100 seeds all at once and never have a shortage of fresh, baby plants again.
