These cubes came packaged well in a plastic wrap. These are genuine Grodam rockwool cubes and are very high quality!

Great for the price
Not much to say, works great for the price. Only needed 4 so used one of the extras to create a plug for the center.

A must if you want double yeilds.
I use these in a 4.4 gallon auto pot with coco and let me tell you. If you want to grow some bricks, use these cubes inside your pot with your grow media. Give a little extra time to veg maybe 2 months with some root inoculant and you will have some plants growing with bark on the stalks. I have done comparison without using the cubes and the harvest is 3x less not using the cubes. Roots look like ropes within pot they are so large. I grew Barney Runtz Muffin as my test. With cubes average 1 plant 6-8 oz dry without cubes about 2-3 oz dry.
