Buying guide

When you are aware of some important aspect of the product, the purchasing will be easier and time saver. Other than that, you will not feel a lack of self-confidence when ordering a specific product.

Let’s get to know some aspects regarding the best medium for ebb and flow systems.

Find your preferable Type mediumThere are countless mediums for ebb and flow systems. Out of them, you have to find your preferred one depending on what type of cultivation you are interested in, what kind of plants are going to be used, and how much space you have.

Some best mediums are clay peddle, coco brick, Rockwool, water farm, and many others. Depending on your needs you have to choose among them. You are allowed to use multiple systems, but it would be better if you got advice from an experienced person.

Check the Nutritional siteThere are multiple mediums available for ebb and flow systems. Some are clay pebbles; some are Rockwool, and others would be water farms or expansion pots. So it’s true that you are not going to get any nutritious value from a water farm or expansion pot, but surely there is a chance to check the nutritious part in clay pebbles or Rockwool. 

As the plant is directly involved with this stuff so the pebbles or Rockwool should be helpful in different ways. So keep this point in your memory.

Weight and Dimension Though this seems a little unintended with the plant’s growth. But still, it’s important to keep in your consideration. 

If your product is a water farm or expansion pot, then make sure your product dimension is big enough. When the dimension is bigger, the space between the pot or bucket will be higher. And that spacing is really good for the plant’s health.

Also, consider the weight. Good product doesn’t mean huge weight. Always try to buy a lightweight product because you might need to hang the tool for fresh air and light. If the product is heavy, it will be difficult to move and hang.


Finding the preferable medium for ebb and flow is a big relief, but you will be more relaxed when you get the best product for that medium. And we want to give you that relaxation by providing the best medium for ebb and flow products. The products we have showcased here are incredibly good in terms of built quality, design, and performance.
