7 Best Hydroponic Trays & Flood Tables to Buy in 2020

In hydroponics, you will find that there are different kinds of hydroponics trays. Trays that are smaller are often used for nurturing seeds into “plugs,” which are small seedlings with few leaves. 

Plugs are often more resilient and able to grow fully, as compared to seeds that are directly planted within a hydroponics system. 

Once the seeds have germinated into plugs of sufficiently good quality, they are transferred into rows for growth into mature plants.

Selecting appropriate grow media

When plants are at the seedling stage, they require plenty of oxygen and air circulation. To ensure these requirements are met, try to use grow media that is catered to starting seedling growth. 

Selecting appropriate fertilizers for seed germination

For hydroponics, there are three types of fertilizing stages – starting, blooming, and maintenance. 

When plants are in the germination stage, fertilizers for the starting and maintenance phases are suitable options. Be careful not to add excessive amounts to the nutrient reservoir, as this can cause seedlings to die. 

Understanding the requirements for healthy plant growth
