Meanwhile, the PowerGrow Systems Deluxe Plant Cloning and Propagating Machine balances low price tag and effective cloning technology.

You’ll notice that the Hydrofarm CK64060 Seedling Heat Mat has the biggest number of cloning sites. While it is enticing, this is only necessary if you have several varieties of plants to propagate.

For areas with dry climate, then I highly suggest opting for the TurboKlone T24D Cloning System because of its humidity and temperature control.

The last two items are the most user-friendly models both for experienced and beginner growers. If you only need a few cloning cells, the PowerGrow 21-Site Cloner and Propagator will suffice.

But if you want heavy-duty and several clones, then go for the HortiPots Aeroponic Cloner System.

Whatever you choose, any model from this list can decrease your workload while boosting yield.

What is a Cloning Machine and Why Do You Need One?

A plant cloner is another type of hydroponic system that is made up of circular boxes or plastic squares. It supports nutrient mixture, pump, and aeroponic spray nozzles.

The holes contain either hard or soft neoprene inserts. These holes are the cloning sites. You can place your plant cuttings into the cloning sites.

When you turn on the water pump, the water forces the nutrient mixture through the nozzles. By doing so, you can cover your cuttings with highly-oxygenated mist.

In traditional propagation, cuttings are suspended in the air. The lower parts are usually misted with nutrient solution.

When it comes to cloning, there are heating pads that warm the cuttings and the nutrient solution.

Furthermore, a plastic lid covers the cloner. Hence, the humidity of the cloning environment is kept for the leaves and their upper parts.

In some cases, there’s no need to place the lid. This is only advisable if the growing environment has low humidity.

Factors to Consider When Buying a Cloning Machine

Cloning Sites or Neoprene Inserts

The number of cloning holes is the most important factor when buying a cloner. In general, the number of neoprene inserts should depend on your needs.

If this is your first time to use a cloning machine, then small systems with at least 20 sites are preferable.

But if you are planning to scale your cloning system in the future, then don’t pick a cloner with few sites. You can initially pick those with at least 30 sites.

Remember that the size of the inserts will dictate how big of a plant cutting or seedling you can place inside the site.

Moreover, be mindful of the space between the sites. Make sure the sites are not too close to each other. If there’s not enough distance, the plants may press against one another, causing damage.

Bucket Size

You can grow more plants if you have a bigger bucket size. Subsequently, the bigger the size, the more depth there is. In effect, the roots can go deeper to enhance plant development.

The bigger the growing space, the more chance for your cuttings or seedlings to receive light, air, water, and nutrients.

Therefore, it is better to opt for a hydroponic cloning chamber with sufficient growing space. In this way, you can aid the plants in growing bigger and faster.

Construction and Design: Simple or Multi-Functional?

A simple cloning machine will include all the basic features for cloning. The basic accessories are the cloning sites, base tray, nozzle, and humidity dome.

But if you are considering additional features, such as a built-in fan, then you may opt for multi-functional versions.

Most units nowadays are designed to keep the reservoir water temperature low. Others come withhumidity dome to helpavoid initial transplant shock and leaf transpiration.

Another necessary feature is a proper pump. It must moderate the flow of oxygen and water to preserve an excellent growing environment. Thus, your cloning system must have the capacity to manage the necessary temperature.

Price: Initial Buyout and Operating Costs

The number of cloning sites, construction, and design will determine the starting price. The additional features can also make the price tag bigger.

Remember that the more cloning sites, the more water and nutrient mix you’ll need to provide. Hence, the more cloning cells, the bigger the operating costs.

Common Queries About Hydroponic and Aeroponic Cloning Machines

What Should I Do Before Cloning?

One to two weeks before the cloning, it’s advisable to give your plants tissue nutrients such as vitamin B. This will encourage tissue strengthening and root growth.

Make sure that your chosen plants are free of pests, diseases, and other problems. As much as possible, select the branch’s top for cloning. Another option is the branch’s end with a stem and few leaves.

Remember: the most rigorous parts of the plant will deliver better outcomes.

Use a clean, sharp, and sterilized knife or razor to take cuttings. Cut at about 45 degrees.

Finally, dip the cuttings into the cloning cells. Keep the cuttings hanging above the machine at least one to two inches below the cover.

How Can I Set Up a Cloning Machine and the Cloning Environment?

  • Fill up the cloning machine to the indicated level with water that is at 18 to 20 degrees Celsius.
  • Attach the nozzle or mister and the pump.
  • Make sure the nozzles can cover the whole surface area.
  • If the humidity level of your cloning environment is under 60%, mist the area of use the humidity dome.
  • Maintain the cloning temperature between 70 to 75 degrees Fahrenheit for optimal results.
  • Check the nutrient solution. Ideally, it must be at 68 degrees Fahrenheit.
  • Cuttings don’t need too much light at this stage. A grow light positioned at about one foot away from the canopy is enough.
  • After 14 days, the cuttings with roots are ready for transplant.
  • If the roots are strong enough and about two inches long, the cuttings are ready for transplant.
  • You can place the cuttings in the ground, pots, or a deep water culture system.

How to Care for Your Cuttings Inside a Cloning Machine

  • If the cuttings look wilted, you can spray them with a foliar spray.
  • The best way to determine if the roots are healthy is to see bright white roots. If the roots are brown or gray, the water temperature may be too high.
  • The first set of roots should form in about seven days. Within 10 days, the secondary roots will pop out. This is the best indication that you can transplant the cuttings.

Do You Need Accessories When Cloning?

Accessories make the cloning process easier and faster. If you think a rooting hormone is necessary, you can buy Clonex or Clonex Mist. They can speed up the rooting process drastically.

Meanwhile, the Clear Rez can keep the reservoir clean. In this way, your roots have a clean environment for optimal health.

Lastly, you may buy extra neoprene collars or misters depending on your needs.

How to Deal with Hydroponic Cloning Machines Running Hot?

The hot temperature is one of the main reasons that hamper cloning success. The cloning environment and pump contribute to the overall heat.

In this case, consider installing an air conditioner or some fans. When it comes to the pump temperature, put a timer to program the pump for occasional on and off.

Final Tips and Reminders

  • Make sure the pump won’t heat up the reservoir too much.
  • You may reset the full reservoir once rooting starts.
  • Lay down heat mats on a smooth surface, but not on steel or cement because they draw too much heat.
  • Clean the cloner, especially the base, lid, sprayers, pump, and cloning cells. You may use bleach, castile soap, or hydrogen peroxide.
  • Clones do not need intense lighting.
  • It is better to use bottled or RO water is you have contaminated tap water.
  • The water’s pH level may impact the effectiveness of a cloning machine. The recommended pH level is 5.5-6.5.
  • Don’t place the cloning chamber uncovered in places or surfaces where air movement is inevitable.
  • Ensure that the cloning system has an optimal humidity level of 75%.
