However, if you’re planning to plant crops requiring less sunlight, look for a spot with shade. 

The Drainage

Ensure you drill holes at the bottom of the pool so that water drains well. A lot of water can make the plant’s roots rot. Hence, it’s advisable to water your crops when you notice your soil looking dry unless the crops require the ground to be consistently moist to thrive.

What’s more, your plants grow and mature more quickly and yield more fresh and tasty fruits. They focus their energy above the root zone growth as they’re constantly supplied with sufficient nutrients. 

Therefore, they don’t need to use their energy to develop extensive roots to search for nutrients. You can use Rockwool or gravel to support the roots. 

Once you plant your tomato seeds, ensure you place them in areas where the temperature ranges between 70 and 75 degrees Fahrenheit. To allow them to germinate properly, you water them several times a day. 

Then, after germination, apply the hydroponic nutrient solution and ensure the seedlings get enough sunshine daily. Next is thinning and leaving the most robust seedlings when the first true leaves pop. 

After 2-3 weeks, you can transfer the strongest seedlings into the growing troughs. It’s advisable to space out the seedling to allow optimum growth.
