He Puts This In A Mason Jar And Watch The Amazing Thing That Happens!

I wanted to learn how to do this so I went in search of a tutorial for the best and easiest way…of course! I ran across these great step by step instructions and I was in business!

This was my first introduction to doing this and I can’t believe how much I learned! I’d never heard of Rockwood cubes and went online to see where I could get them and what they actually are. I found out that it’s a process similar to that used to make cotton candy, basalt and chalk are spun into Rockwool, which is turned into cubes.

Rockwool is a brand name; the generic term is rock wool. Rockwool cubes, 1 or 2 inches wide and 1 1/2 inch deep, are used for germinating seeds for seedlings that are then transplanted into soil or hydroponic gardens. Cubes 3 and 4 inches wide are used as a primary growing medium for small plants. Rockwool has a high pH, so you have to adjust your water or growing solution to fit the needs of your plants.

This is where the mason jar comes in handy. He uses a wide mouthed mason jar and puts a net pot in the top of it, followed by the Rockwood cube and his seedlings or cuttings. I was amazed at this process and got busy gathering up my supplies right away!
