This video details one method for transplanting seedlings from rockwool growing cubes into soil. Rockwool is a hydroponic growing medium made from uncompressed basalt and chalk fibers. While rockwool works great for starting seeds, once the roots of the seedling begin to show through the rockwool cube, it is time to transplant the seedling into soil or another growing medium.
The steps shown in this video can also apply to transplanting from peat moss plugs, coco coir bricks, or smaller soil container. For more information on all things gardening, check out the University of Arizona’s Master Gardener page!
