Excellent .. holds moisture much longer, less water required. Plants are going crazy!
I've used these bricks before and find them a good "filler" to potting soil - esp seedlings that have a tendency towards damping off as the coir dries out quickly. the advantage is also a disadvantage - they dry out quickly so you need to pay attention!
I have used the coconut fiber as a substitute for peat moss for years now and love it. The plants do too. I mix it with a compost mix without peat for a great seed starting medium. If you use the coconut fiber by itself, you need to be diligent with the watering because it dries out quickly in the sun. I use hot water to expand the fiber which gives the seeds the warmth they love for germination. Happy Seed starting!
