This is required for making soil and its WONDERFUL
I love this block!!! We do a ton of seed starting and this is the perfect amount for all of my mixes!
These coco coir bricks are fabulous for the garden and for helping our soil here in the dry and hot southwest in retaining much needed moisture. I highly recommend this product for all serious gardeners.
I have been searching for a cheaper way of getting coco coir for my potting/soil block mix. Smaller bricks add up fast in shipping costs if you use larger quantities and cheaper products are often have rocks or lots of long fiber chunks. I screen my coir through 1/4" wire and there has been very little that won't pass through with this coir. I am very satisfied with it so far!
I bought this coconut coir to help rejuvenate old potting soil which I used to just till into the garden. With coir and added nutrients, the old potting soil is good as new, and much more loose and friable than new soil after a couple of months of watering. I even tried it for growing potatoes (an unusual endeavor for the New Mexico climate) and the plants are growing just great, although it's still early in the season. It holds water well and the tubers should be free to expand when they start to bulk up.
