Abdullah Al Mahmud, an agronomist specializing in plant production, emphasizes the importance of choosing inputs suitable for hydroponic cultivation.
These specific inputs contain fewer impurities and lack the waxy coating found on conventional fertilizers like calcium nitrate.
Furthermore, he advises the use of ready-to-use solutions with the following characteristics:
- Compatibility, with no risk of chemical reactions.
- Full water solubility.
Hydroponic producers typically prepare solutions that are 100 to 200 times more concentrated than what they dilute for actual use. This method requires a high level of expertise, particularly in controlling concentration and solubility.
Otherwise, the portion of insoluble fertilizer salt will form a precipitate, potentially clogging the systems and becoming inaccessible to plants.
Mixing various fertilizer salts can also lead to the formation of insoluble salts, such as when calcium is mixed with sulfate or phosphate.
