The irrigation of crops should be based on the different species. In the case of Phalaenopsis and Paphiopedilum it is convenient to keep the substrate continuously moist, these species do not have the pseudobulbs that are responsible for storing water, for that reason they need frequent watering. It is important that the surface is wet but not soaked or flooded.
Other factors that can influence irrigation are the type of soil, ambient temperature, ventilation, light. The more light and more temperature should be watered more. If they are in clay pots, keep in mind that the walls are porous and the water evaporates more easily.
Irrigation always be early in the morning so moisture is maintained throughout the day. Orchids do not tolerate a lack of water, but neither do they tolerate excess. Stagnant water can become deadly, since they rot their roots.
Never use saline waters or limestone waters. The water may have excess salts, this is easy to detect, when you see a white border that appears in the pots, at ground level. This type of problem cannot be rectified, so avoid using it to irrigate your orchids.
The water it contains high levels of lime It is also not good for orchids. Ideally, rainwater should be used, but if it is not possible you can add a tablespoon of vinegar for each five-liter drum of water you use to water the plants.
Best of all would be to store rainwater in covered plastic drums. If you prevent the appearance of algae and bacteria from entering the light, water can be used indefinitely. In these cases it will not be necessary to add anything, neither chlorine nor algaecide nor vinegar.
