What are the cultivation methods for hydroponic cactus?
Everyone knows that cactus is fairly drought-tolerant, but few people know that cactus can be grown hydroponically. Next, let's take a look at the hydroponic method for cactus.
It is a technique of growing plants without using soil, only carrying the nutrients needed for plant growth through water, or also using materials that support the plant roots, such as wood fiber, sand grains, foam, mineral wool, etc.
In a broad sense, hydroponic cactus means: plants that originally grew in soil are cultivated through hydroponic techniques. Then the plants are grown in nutrient solution. The so-called "water" actually refers to the nutrient solution for hydroponics. Because nutrient solutions have different densities, they look similar to water. Hydroponic cactus is taking a soil-cultured cactus, cultivating it, and then converting it into a hydroponic cactus.
Cactus, also known as changshengqiu and commonly called caoqiu, is a perennial succulent herbaceous plant of the Cactaceae family. Cactus is a soil-grown plant, but after certain hydroponic technical treatment and domestication, cactus can also be grown in nutrient solution, and this is hydroponic cactus. Hydroponic cactus has a wide range of uses. Especially for ladies in the office, it can be used for cultivating the mind and character. The cultivation methods for hydroponic cactus and the daily care methods for hydroponic cactus are things that everyone who wants to grow hydroponic cactus must master.
Although cactus has spines, it has extremely strong drought tolerance and a cute appearance, and it has long been favored by many female friends. The best growing environment for cactus is soil culture. It can grow well with almost no care; if used for ornamental purposes, soil culture is dirty, obviously not very suitable, and does not fit the aesthetic taste of female friends. Therefore, hydroponic cactus is the best choice, clean, hygienic, and highly ornamental.
How to grow hydroponic cactus 1. Select the mother plant
We should first select a cactus with a robust body. The key is to choose a plant whose lower root-stem part protrudes downward. Cactus cultivated by grafting with Sanlingjian is easier to grow hydroponically.

After selecting the mother plant, completely cut off the original dead roots under the body, and require the cut to be flat. Then rinse the soil attached to the root-stem part with clean water, and dry it in a dry place for 3 days so that the cut is completely dry. For cactus mutation induction to remove soil-grown roots, this is necessary. Because cactus is a succulent plant, drying it for a period of time before induction is more beneficial for root induction, because the root induction of succulent plants has relatively strict water requirements in the seedbed. Too much water makes rot easy, and too little affects the effect of root induction.

In terms of effect, the nutritional stress caused by clean water can better accelerate the formation of root aeration tissue and the development of water roots, but from the perspective of cultivation, it is better to use a nutrient solution of appropriate concentration in the water. This is related to the fertilizer tolerance of the plant after mutation induction.

Buy two magnets with a diameter of 6-10cm and put them into the container, in order to magnetize the nutrient solution, thereby speeding up the emergence of water roots. (If conditions permit, you can also buy a small wall-mounted submersible pump specially for ecological fish tanks from the market, attach it to the inner wall of the nutrient solution, and energize it to achieve flowing and oxygen-carrying circulation of the nutrient solution.)

Place the planted cactus in an environment with relatively strong scattered light, keep the temperature above 20 degrees, and generally water roots will emerge in 3-7 days. After water roots appear, replace the nutrient solution immediately.
