Today, I’d like to introduce the water circulation oxygen supply of hydroponic vegetable nutrient solution.
Are hydroponic vegetables safe? The answer is yes, it’s safe and harmless. The nutrient solution has no pesticides and no hormones.
Lettuce, tomatoes and cucumbers in many supermarkets are also hydroponically grown.
Five-star hotels also use hydroponic lettuce for salad.
Here we use a water pump to circulate dissolved oxygen in nutrient solution.
The nutrient solution is pumped out to the hydroponic tank on the upper layer by the water pump, circulates into the hydroponic tank on the lower layer, and then enters the nutrient solution container to complete the whole water cycle.
Each nutrient solution container is supplied with four vegetable hydroponic tanks.
The roots and stems of vegetables are completely immersed in nutrient solution to complete nutrient absorption;
Different crops have different sizes of rhizomes.
This is basil. This is lettuce.
Koray, to serve modern agriculture with high-quality grow light!
