First of all, we should choose the cactus with strong physique, and we should choose the plants with protruding bulbs for hydroponics.
Cut off the original dead roots of the sphere. Wash the soil at the root with clear water, put it in a dry and ventilated place to dry for 3 days, and then remove the mutation root of cactus.
Clear water can accelerate the aeration of roots, make them abandon the soil roots, and form the development of water roots. Proper concentration of nutrient solution should be prevented and controlled in the water, which is helpful for the fertilizer tolerance of plants after mutation.
2. prepare a transparent and suitable glass bottle, fix the processed cactus with foam in the mouth of the bottle, add the nutrient solution.
The water level of hydroponic cactus should not be more than half of the root.
Two 6-10cm magnets need to be used. Put the magnets into the container to magnetize the nutrient solution, so as to accelerate the generation of aquatic heel.
Place the planted cactus in the environment with scattered light, keep the indoor temperature above 20 ℃, and generally send out aquatic roots in 3-7 days. Replace the nutrient solution immediately after the occurrence of aquatic roots.
