The germination process is a very delicate time for plants. Although we can do it with different mediums, Rockwool has been proven to increase germination rates. Rockwool is hydroponic, and since germinated seeds need a lot of moisture, this makes it perfect for germinating plants in Rockwool cubes. This blog post will go over 9 plants that are great to germinate in rock wool cubes!
What Are the 9 Plants That Are Great for Germination Using Rockwool Cubes?
The following 9 plants germinate well in Rockwool cubes:
- Herbs (basil, thyme, etc.)
- Flowers (petunias, geraniums, etc.)
- Melons (cantaloupe, honeydew, etc.)
Tomatoes germinate in Rockwool cubes because they need a lot of warmth and moisture to get started. The humidity levels in rock wool are perfect for germinating tomato seeds, and the pre-sterilized cubes help keep everything clean.
Cucumbers, zucchini, lettuce, herbs, flowers, melons, and strawberries also germinate great in Rockwool cubes because of the heat and humidity germinating seeds need.
How to Germinate Using Rockwool Cubes?
When germinating plants, you want to make sure the medium you are using is sterile. Rockwool cubes are a great way to ensure this because they come pre-sterilized. Not only does Rockwool provide a sterile growing environment for your plants, but it also helps keep the humidity levels high, which is crucial for germination.
Furthermore, germinating plants in Rockwool cubes is easy! Just follow these 5 steps:
- Poke holes into your Rockwool cube with a pencil or something sharp (preferably facing up) to give room for roots to grow out later on
- Fill a container with water and soak the Rockwool cube in it until thoroughly moist
- Put your germinating seeds onto the top of the Rockwool cubes
- Cover germinating seeds with another layer of soaked Rockwool cubes to help retain moisture and heat for germination. Make sure this is done gently, so you don’t hurt germinating seeds
- Put your germinating Rockwool cubes in a sunny spot where they will get plenty of warmth and moisture. Germination usually takes about one week, but it can take up to three weeks for some plants!
What Should Not Do When Germinating in Rockwool?
It would help if you avoided a few things when germinating plants in Rockwool cubes. First and foremost, do not over-water your plants! Rockwool can hold a lot of water, but it can also become saturated quickly. Over-watering will drown your plants and could kill them.
In addition, be sure to monitor the pH levels of your growing medium. Rockwool is pH neutral, but if the pH levels of your water or soil are off, it could harm your plants.
Finally, make sure to keep your germinating plants in a sunny spot with plenty of warmth. Not only will this help germination occur more quickly, but it will also help your plants grow healthy and strong.
Benefits of Using Rockwool in Hydroponic.
The main benefit of using Rockwool is that it can hold a lot of water while remaining porous.

Germinating plants in Rockwool cubes is easy and offers several benefits to commercial growers. Not only does it keep germinating seeds at the right temperature, but it helps with root growth as well! This means that germination rates are comparatively higher in rock wool. In addition, this material is pH neutral and doesn’t contain any harmful chemicals, which make gardening safe for all ages.
Take all precautions before handling Rockwool for your safety. Soil moisture and pH levels should be constantly monitored when using Rockwool in gardening.
