5 Common Reasons Behind Poor Yields in Your Harvest – What to Know for Rookie Growers

Hydroponic growing offers plenty of key advantages as it allows growers – rookies and seasoned alike, to benefit from water/energy efficiency, better pest control, and more space to save. Seeing as it allows for more control on the nutrient intake of the plants, any mistakes in the process can make a significant impact on your harvest results.

Errors are inevitable in hydroponic culture, especially if you consider the steps you need to take to turn your plants into the cream of the crop. Consequently, it helps to know the common problems you may encounter that are likely to compromise your actual crop yields. With that in mind, consider the early warning signs below:

Sub-Optimal Vapour Pressure Deficit

Plants are generally designed to withstand different environmental conditions, but the humidity level and temperature are both factors that can make or mar the overall health of your plants. It also influences an optimal crop based on factors like the carbon dioxide in the air, the species of the plant, and the appropriate nutrient solution that was fed to the plants.

Many growers struggle with controlling the temperature and humidity, especially during extreme weather conditions like summer or winter.

Poor Environment Surrounding the Root Zones

Plants typically absorb nutrients through their root zones, but that doesn’t mean you should forget about the leaves. Some nutritional additives are absorbed with better efficiency when sprayed on the leaves, which helps enhance the plant’s growth pattern and produce an impressionable yield come harvest time.

Ignoring foliar spraying leaves out plenty of potential growth in the process, so be sure to give equal attention to both the root zone and the foliage.

No Silicate Applications

Potassium silicate is an essential additive that plays a pivotal role in fighting off fungal or bacterial diseases. It’s crucial to include in your hydroponic growing process as silicate applications can help boost the plants’ immune system. After all, a stronger and healthier crop leads to a higher yield count at the end of the season.

Forgetting to Adjust the Nutrient Optimisation

The necessary nutrient intake varies depending on the plant species, medium, temperature, humidity levels, and carbon dioxide conditions. There are standard nutrient solutions that can produce a reliable performance in feeding the plants, but opting for a tailor-made nutrient solution allows you to fill any nutrient deficiencies and maximise the plants’ potential.

Specific nutrients like phosphorous and calcium, for instance, can be optimised according to the particular set-up and hydroponic condition of the grower.


Understanding the common factors that can affect the quality of your crop’s yields can make a world of difference in your growth strategy. It can help get you started on the right foot in your research as you try to find optimal ways to fix these issues.
