Cultivation techniques of lettuce
Oct 27,2022
the technology of growing seedling Sowing was carried out in the greenhouse. Coconut bran matrix was placed in a 72-well hole dish, and then placed on a tidal Greenhouse seedbed. Nutrient solution (EC: 1.6 mS/cm, pH: 7.4) was poured to saturate the substrate with water absorption. The seeded hole plates are placed in a centralized manner according to the varieties, and the varieties and sowing dat...

What is the difference between drain to waste system and recirculating system?
Jun 26,2024
Drain-to-Waste System: How It Works: Nutrient solution is delivered to the plants. Excess solution, which is not absorbed by the plants, drains away and is discarded (wasted). Fresh nutrient solution is prepared and supplied to the plants regularly. Advantages: Nutrient Consistency: Plants always receive a fresh supply of nutrients, ensuring optimal growth conditions. Simplicity: These systems are...
