  2. Seachem Fluorite Black Sand Substrate, 7.7lb
  3. Aqua Natural Galaxy Sand Bio-Substrate 5lb
  4. Seachem Flourite Black Clay Gravel

When the substrate is ready and done, it is time to sow the seeds in them. Get the seeds in the substrate and then spray some water in them. Then wait till the seeds germinate and the seedlings appear.  

Add water to the aquarium 

You need to wait till the seedlings grow about 3 inches tall to add water to your tank. Once the plant has grown to a suitable height, you can add the water slowly. Although at first do not submerge the plant fully in the water.  

Let the plant sit in the water for some time for the plant needs to get used to it. After some time, you can add more water to the tank. You can also add your fish and other item to your tank.  

After this, you can watch the plant grow in your aquarium. Plants not only provide aesthetic pleasure to the tank, but they also take in excess nutrients in the tank, provide oxygen to the fish, and many more. Therefore, having plants in an aquarium is not a loss at all, but you need to take care of them for them to provide benefits.  

Do aquatic plants have seeds?  

Aquatic plants do have seeds. You can get the seeds for your aquarium from an aquarium store or online. But when it comes to carpeting plants, you should use propagation rather than seeds.  

The carpeting plant seeds you get online are not reliable and will make your aquarium hideous. Instead of carpeting plants, the seeds are of some kind of weed that cannot survive in water for long.

Therefore after growing and being green for some days, the plant dies off leaving behind a mess.  


Growing aquarium plant seeds opens up a world of possibilities for aquarists seeking to create a vibrant and personalized underwater oasis. Throughout this guide, we’ve explored the step-by-step process of germinating and nurturing these tiny seeds into thriving aquatic plants.

Remember, patience is key when it comes to cultivating aquarium plant seeds. It may take time for the seeds to germinate and develop into healthy plants, but the rewards are well worth the wait.
