How to germinate seeds for hydroponics without Rockwool?

Germinating seeds for hydroponics without Rockwool is actually very easy. In the past, when people had to germinate seeds for hydroponics before Rockwool was invented, they were germinating them in a glass of water. That is basically all you need to do today too.

The most important thing for successful hydroponic seed germination is to make sure that your water is at the right temperature. If it’s too cold, the seed won’t sprout. If it’s too hot, you change the chemical balance in the water and your seed might not survive that either. The perfect germinating temperatures are between 20-25 degrees Celsius (68-77 Fahrenheit).

To make sure you achieve this, simply fill up a glass with water, make sure it’s room temperature, and put your seed in there. That’s literally all there is to it.

After the seed has sprouted, if you grow it hydroponically (in water), you will now need to remove the Rockwool or any other growing media from the seedling. Be extremely careful not to damage the roots. They are very sensitive and if you do any more damage there, it will be difficult for your plant to absorb its nutrients and grow further. If this happens, make sure to transplant it as soon as possible.

The best way is probably still by putting the seedling in a new glass until it has developed roots of its own. There is the risk that you might over-water it if your seedling is in a glass, but aside from that, there’s not much to worry about.

What to use instead of Rockwool for hydroponics?

Well, pretty much anything will work! If you are looking for an alternative to rock wool that is easier to handle, perhaps because it’s not as rough on the hands as Rockwool, try using coco coir. This is made of coconut husks and will provide a much better experience all around. So now that you know all about how to do it, go ahead and give it a try!

Well, the best thing to use for this is anything that will hold water. Just take a container with some form of drainage and fill it up with your chosen germinating media until just before it spills over. The next step is to simply place your seeds on top of the substrate. It’s important not to bury them too deep because they might not be able to break through the surface at all. Keep that in mind, and you should be good!

Now wait until your seeds have sprouted, and then you can decide what to do with them. There are a few different options. You could transplant them into glass hydroponics (where they will stay until their roots are well developed), or you could just keep them in the container they grew in, adding some water every other day.

If you’re growing your sprouts for longer than one week, it’s probably best to transplant them at this point because they will need something more than just sitting in a container filled with water. But if they are less than a week old, they should be fine just sitting in that container.

That’s it! You now know how to germinate seeds for hydroponics without Rockwool. Good luck and happy growing! You may also like to read this article germinating seeds in paper towel in House I love.
