What key points should be paid attention to in hydroponic flowers

The main points that should be paid attention to in hydroponic culture are as follows:

① uses a larger glass jar or vase as a container, surrounded by black paper or film, which is beneficial to root growth after shading.

② fastens the flowers with foam panels.

③ nutrient solution should not be too full, there should be room for flowers to breathe oxygen.

④ roots are immersed in nutrient solution, but about 3 cm of roots are exposed on the surface of the water.

⑤ needs to replace all the nutrient solution in the container every one month or so.

When changing the liquid, ⑥ should prune the bad roots and pay attention to keeping the water level consistent.
