Best Propagation Kit

Last Updated: March 23, 2023

Product Review by Roy Stevens

In technical terms, propagation is when you reproduce an organism through natural and unnatural means.

The propagation phase is one of the most exciting phases an indoor grower will encounter, probably second to actually harvesting your hard work and getting to enjoy the fruits of your labor.

Plant propagation occurs in one of two ways; either cloning your cuttings or sprouting from germinating seedlings.

Both of these ways have their own unique advantages and disadvantages but from a grower’s perspective both require the same basic equipment so both are as easy to achieve as the other.

One piece of equipment that growers always gravitate to when trying to achieve propagation is the Propagation Kit.

Purchasing the best propagation kit will deliver an economical, efficient, and end-to-end product that has been purposely designed to provide growers with everything they need to achieve propagation.

There is, however, a multitude of options available for the average grower looking to purchase a Propagation Kit, and many growers suffer from choice paralysis when confronted with the many different options available on the market today.

Propagation Kit Buyers Guide

As you can see from the five propagators we have chosen, there are some significant differences between products and definitely some eye-catching innovations that stand out, but what are the important factors you should consider before deciding on which propagator is right for you?

We have compiled a checklist of five important points that you should think about when deciding which propagator best suits your needs, always remember of course that purchasing decisions should take into account your maximum budget and that you should only buy what you can afford.

Propagator Size & Potential Yield

One of your most important considerations is going to be the desired size of your propagator and if the product meets the necessary criteria.

All of the above propagators that we have covered in our review come in different sizes and some can come in still more sizes (whether that’s through buying a different size variant from the retailer or increasing the size of the propagator you have with extensions).

It’s no use buying the largest propagator on the market if you don’t have the size for it but conversely, it also won’t be economical if you wish to make large yields by purchasing a too small kit.

Always measure the area where you are going to be using the propagator and ensure that not only does your kit have access to the requisite amount of light but that it is also situated with enough space that you can easily and quickly monitor and adapt the environment should you need to.

If this is your first time using a propagator kit then it might be more appropriate to purchase a smaller propagator and learn the basics and then if you are happy with the results you can purchase yet another and double your yield instantly.

However, if you are more experienced in using propagator kits but are looking for something new the below consideration factors may weigh more heavily as you will undoubtedly already know what size suits your needs best.

Ventilation Control

It is critical that your plants get the correct amount of oxygen but it is also super important that they are kept at the right temperature and humidity, this is why ventilation control should definitely be a consideration factor when choosing which kit to purchase.

Many of the propagation kits we have covered have inbuilt, easy to use, ventilation shafts that can be opened and closed as necessary depending on the environment, plant type, and growth progression.

Although purchasing a propagator kit without ventilation holes will undoubtedly be cheaper without having that level of control over your growing environment you may struggle to achieve the best results or even worse be unable to rectify your growing environment should the humidity or temperature begin to become untenable for your plants.

For the sake of spending a few more dollars at the outset, you could very well save yourself from having to get rid of wasted crops and going through all of the time, effort, and expense of starting again.

Seal Quality

Another vital component of the propagator to consider is its ability to create a good seal, as this has a massive effect on the propagator’s heat, humidity, and overall efficacy.

Some of the more affordable options may not be as diligently crafted as the more premium kits and as such there may be warping, distortion, or a break in the seal.

Now while it is possible for even the most expensive and well-reviewed products to have one specific poorly made product in the batch, a good rule of thumb when deciding which kit to buy, is to look at reviews and ensure the same problems aren’t constantly referred to, as this would indicate the problem is widespread.

Again, as a general rule you are unlikely to find consistent, widespread seal malfunctions on the more premium and well-reviewed propagator kits but of course if you do you can always return it back to the retailer and request a replacement or full refund.

Customer Reviews & Budget

We cannot over emphasize how important it is when planning to spend a significant sum of money on a project for you to research and review all your options to find the most suitable and cost-effective product for you.

Whilst we always strive to give a full, frank and honest opinion of the products we review, it is undoubtedly the case that other experienced growers may disagree with our findings and we encourage you to cast your net wide when researching and listen to all customer reviews you come across.

By researching customer reviews of the product you can hopefully gather enough information to help you purchase the right kit for your needs.

However, even more important than researching the product you are potentially buying is having a fixed budget from the outset.

It has never been more important to keep a strong hand on your purse strings and keeping a budget firmly in your mind will help you immediately whittle down prospective products and find the most suitable one for you.

Extras and Additional Kit

Lastly, always keep an eye out for a bargain, many retailers are now throwing in extras or additional pieces of kit as standard, for instance, one of the propagator kits we have covered above includes a guide on propagator kits and how to use them which would definitely come in handy for any beginners considering this particular kit.

Extras that are going to help you get the most of the product and optimize your growing environment are tremendously valuable and not only do they make using your propagator kit more enjoyable but they could potentially make it more economical and therefore end up saving you money.

Once you have thought about all these considerations, completed your research, and fixed your budget in mind you should be almost ready to make your decision on what propagator kit is right for you.

When we review any product at The Highest Crop we always conduct in-depth research about both the product itself and customer reviews for the product in question and we are happy to say that our pick for “best of” is normally well received and virtually unanimously agrees with.


Taking into account all of the above important considerations and mulling over each kit’s respective pros and cons we have chosen the Super Sprouter Premium Propagation Kit.

A fantastic and affordable propagation kit, the Super Sprouter comes with everything you need to begin your growing journey, even a handy little guide that takes you through the basics of propagation and how to make best use of your kit.

Made from high-quality materials and coming with an excellent reputation, this propagator will allow you to produce large, high-quality yields with minimal effort and cost.

An excellent investment and a savvy purchase the Super Sprouter Premium Kit is a kit you can and will come to rely on during this crucial growing phase.
