My favourite is called GT CCS, made by the same company who make Clonex. You can get CCS from Amazon also. It's a complete root fertiliser, gentle enough for cuttings and seedlings, and also formulated for use in water, not just in soil.
The best fertilizer for root growth is one that is high in phosphorus, as this nutrient plays a key role in root development. Fertilizers with a high middle number in the NPK ratio, such as 10-20-10 or 5-10-5, are ideal for promoting strong root systems.

1) Light - The more light you can provide, the faster a cutting will photosynthesize and the faster it will produce roots. We know that light intensity drops significantly with distance, so keep cuttings in front of windows. Bright light is over 3000 lux but the more you provide the faster they will root.⠀ ⠀ Or buy gr.
As stated, the best nutrients for root growth are potassium and phosphorus. Potassium plays a role in the transportation of nutrients and water in a plant.
All you need to make a rooting powder with apple cider vinegar is the vinegar itself and water. You only need to add one teaspoon to each 1.2 to 1.4 litres of water. This should give the plants a slight boost to help them root successfully.
For plant roots to grow faster, it requires nutrients, sufficient water, well-aerated soil, enough light, the right range of temperature and proper amendments. Nitrogen, phosphorus and potassium are the three essential nutrients that a plant requires for its growth.
Apple Cider Vinegar Rooting Hormone
All you need to do is mix 3 teaspoons of apple cider vinegar into 1 gallon of water and dip your cuttings in it, then transfer them to the rooting medium.
Add a Pothos! I'd heard of using willow as a natural rooting hormone (no idea where to source that however), but didn't know Pothos has this 'super power' too! Just pop a Pothos cutting in with the water with your slow-to-grow cuttings and it helps speed up root development.
Perlite is another excellent propagating material. It is lightweight and provides good aeration to the cutting. Perlite gives best results if mixed with an equal volume of peat moss or vermiculite.
Understanding fertilizer numbers
If you were looking for something more appropriate for transplanting, when you want to promote root development, you would want a higher middle number such as a 2-8-4. The three elements we are discussing above are just the basics–the primary macro-nutrients.
This starting solution improves root growth for faster blooms compared to unfed plants. Miracle-Gro® Quick Start® Planting & Transplant Starting Solution is ideal for all flowers, vegetables, trees, shrubs, transplants, and seedlings.
Epsom salt promotes deep root growth for plants so during times of drought or little rainfall, Epsom salt plants will have deep roots to seek out moisture and nutrients. Plants with deep roots thrive when other plants with shallow roots shrivel up and die if water is not constantly provide to them.
Distilled water: Distilled water is a good choice for houseplant propagation because it has had all impurities removed through a distillation process. This means that it is free from minerals, chlorine, and other chemicals that can harm or hinder the growth of the cutting or the new plant.
On the other hand, soil will have nutrients, which will speed up growth. As such, hardy cuttings can be rooted directly in soil to speed up the growth process and remove the need for transplanting. Cuttings in soil and soil amendments will need to be watered at least once a day to keep the cutting fresh and growing.
To use apple cider vinegar as a rooting substance, mix a teaspoon with five to six cups of water (1.2 to 1.4 liters). Dip the cut ends of stems into the mixture for a few seconds. Place the cuttings directly in prepared and moist potting mix.
In many cases, sugar application increased the number of new roots formed by week 6 but had no significant effects on the length of existing roots or shoot growth.
After weeks of giving each plant different liquids(water, carbonated water, mango juice and pineapple soda), the conclusion is carbonated water grows plants the fastest and the healthiest.
Some plants will root in water, but cuttings will develop a better root system when rooted in a soil-less potting mix. Sand or perlite can also be used, especially for cuttings that need good drainage and may rot if kept too wet.
Cinnamon as a rooting agent is as useful as willow water or hormone rooting powder. A single application to the stem when you plant the cutting will stimulate root growth in almost every plant variety.
PRO TIP If you have a Pothos in your collection, another tip to speed up root growth is to add a pothos cutting to the same water as the cutting you're waiting to root. Pothos release a natural rooting hormone into the water that helps trigger root growth in other cuttings sharing the same water.
The two main nutrients that support excellent root growth in plants are phosphorous and potassium. These two ingredients are extremely helpful in any fertiliser mix that needs to encourage a thick, healthy collection of brand-new roots, or to strengthen and stimulate existing systems.
Auxin, a naturally occurring plant hormone, stimulates root formation. Several synthetic forms of auxin are sold as “rooting hormone.” Though some plants will root readily without treatment, application of rooting hormone to the base of the cutting will often improve your chance for success.
