Although hydroponic flowers have many advantages in cultivation and appreciation, not all flowers can adapt to hydroponic cultivation. Whether hydroponics can be cultivated depends on the growth habit and internal structure of plants. People will suffocate in a room without oxygen, so will flowers. It needs not only water, fertilizer, light and temperature, but also enough oxygen for breathing. Most flowers are not suitable for hydroponics because their roots will die of lack of oxygen in water. According to the cultivation experiment, there are the following kinds of flowers suitable for hydroponics. 1.

Most Liliaceae flowers can adapt to the conditions of hydroponics, such as Fuguizhu in Phnom Penh, Yinjilan, Yinjilan, Ophiopogon japonicus, Eupatorium odoratum, Diancaishijuan, Tequila and so on. 2.

Most flowers of Araceae can be cultivated in hydroponics. They include Camptotheca acuminata, green radish, Guangdong Evergreen, Turtle-backed Bamboo, Hulk, Spotted Evergreen, Green Princess, Fruit Taro, Flammulina velutipes, Calla lily, Spring Feather, Silver Bract Taro, Emerald Gem and so on. They can also spread through water. As soon as water is inserted, they can take root in a short time and grow rapidly after taking root. Sometimes the stems and leaves of Araceae plants, such as Camptotheca acuminata, are cut off after changing pots in greenhouses and discarded by ditches, and can take root in a few days. 3.

Sedum crassulaceae is mostly succulent flowers, and its body contains a lot of water. If it is not properly managed in hydroponics, it is easy to rot and die, especially in summer.

The flowers that can be hydroponically cultivated in Sedum are lotus, silver brocade, gem flower, rooting flower, hibiscus flower and so on.

4. Almost all Ardisiaceae flowers can adapt to hydroponics, such as Lophatherum gracile and Ardisia japonica. 5.

Peach-leaf coral and golden-sprinkled peach-leaf coral of Cornaceae are water-resistant and moisture-proof and suitable for hydroponics.

6. Other flowers that can adapt to hydroponics are: ivy, Eupatorium odoratum (spider holding eggs), amaranth, pineapple, wild begonia, Parthenocissus tricuspidata, brown bamboo and so on.
