Rockwool cubes provide a haven for seeds during germination. By keeping them sufficiently saturated, they provide the three key demands required for successful germination: darkness, moisture, and warmth.
Rockwool is a great medium for growing marijuana. You can take your strain of choice through the whole cannabis life cycle with rockwool. Growers of all levels, using a variety of hydroponic setups are harvesting heavier yields a whole lot sooner. It’s about time you tried rockwool too.
Cons of Rockwool for Growing Cannabis
Second, consider wrapping a rubber band or soft garden tie around the middle of the cube to ensure it doesn’t break in half during the next grow.
Before you pop your seeds into the cubes, you’ll need to adjust the cubes’ pH to make them less alkaline. This step also gives you a chance to infuse nutrients into your cubes to give your seedlings the best start to life possible.
The structural integrity of a Rockwool cube will also deteriorate after a single round of growth. As the thick and strong main roots develop, they’ll make holes in the cube, in turn making it less able to accommodate another set of roots in the future.
Hey i really do need a BEST advice how to start my uniq seeds in high success rate! Some of my seeds may be damaged over years, but i need to try to save them!
seedlings in them you would not have to water for about a week maybe longer.
germinate them them move them to the rock wool cubes
I use the paper towel method 100 percent success rate for me, then once the little white tail pops out of the seed, then move the seeds to the 1 inch rock wool with the tail facing down in the hole then lightly put a little piece of rock wool over the hole that the seed is in.

Step 1: Place a folded wet paper towel into a plastic container, or on a plate.
3 days. Once the first true leaves emerge, we want to select for the strongest one (the one that grew the tallest), and cut off the tops of all other seeds that are growing next to it. Do not pluck them out, as you may uproot it’s neighbors. Simply cut it off as close to the hole as you can without messing with the stronger one that you plan on keeping alive.
Peat plugs are an organic option, and sometimes contain a small starter nutrient charge which helps young seedlings after germination.
4. Paper Towel Method
Step 1: Purchase quality soil from a reputable source. You want soil with good drainage, this allows for air exchange; seeds need moisture but you don’t want to drown them.
Rockwool Cubes have a PH of roughly 7.8. This is pretty alkaline, yet our plants prefer to grow in a slightly more acidic environment (between 5.5 – 6.5). In order to prepare our Rockwell cubes for the seeds, we need to soak them in some PH adjusted water, that way they have everything the seeds need to germinate and sprout; water and a slightly acidic environment.
Germinating with starter plugs or cubes is easy and the most reliable method on this list.
Step 1: Place your seeds in a container of clean water and allow to soak overnight, or for at least 12 hours.
