Dealing with Root Slime in Hydroponics

If you’ve ever struggled with root slime while growing plants hydroponically, lost your crop, or ended up with stunted plants, this article is for you. There’s a miracle fungicide from Bayer called “Previcur Energy” that can solve all your problems.

My First Experience with Previcur Energy

Let me share how I first discovered this product. One spring, I bought a new DWC (Deep Water Culture) system for six plants. The kit included a bag of imported expanded clay pebbles. Without thinking about rinsing or treating them, I just poured them into the pots and stuck in the rockwool cubes with my seedlings. I set everything up under the lights and left, feeling satisfied.

When I checked back a few days later, the plants had stretched but looked unhealthy. I pulled out the pots and saw that all the roots were covered in slime. The water was cloudy and dirty. Panic set in. I tried everything I could think of, but nothing worked. I spent my days and nights worrying, scoured forums, and messaged experienced growers—still no solution. I completely blocked light from the reservoir, changed the solution, cleaned the tank, replaced the air pump filter, added hydrogen peroxide, rinsed the roots in a potassium permanganate solution, and washed all the clay pebbles. Nothing helped. I was about to give up on the whole cycle.

But as the saying goes, “seek and you shall find.” On one gardening forum, I came across Previcur Energy. I searched every local garden store—no one had even heard of it. Finally, I found it in an online store and went to pick it up. The bottle cost about 400 rubles. I had almost lost hope.

I poured the product into the reservoir at the ratio specified in the instructions. I immediately heard a hissing sound from the tank, which continued for two days. At the time of treatment, the roots were slimy and not developing at all, and the plants were suffering. Imagine my surprise on the second day! When I pulled out the pots, I saw snow-white strands of roots growing out of the yellow slime (dead roots). After using Previcur Energy, everything went smoothly. The product even cleaned and polished the airstones, removing all the algae slime! Since then, I always keep this miracle product on hand.

Tips for Using Previcur Energy

• Do not use it regularly. Add it just once during the week as needed.
• If you overdose, the plant will experience severe stress and may either flower prematurely under any light cycle or turn hermaphroditic.
