You can Improve germination and root growth with this coconut fiber brick.  It is a premium seed starting mix in one compressed brick made of renewable resource coconut fiber. All you need to do is add water and the brick expands to a volume of about 8 quart in minutes.

WHAT WE LIKE

Great for seed starting over the winter months when you may not have access to fresh soil and garden centers have none in stock due to being out of season. It expands quite a lot so it’s best to put the coir brick into a good sized bucket. This is a great alternative soil option if you know how to properly use it and care for the plants. Inexpensive and very easy to use.

WHAT WE DONT LIKE

If you water it often based on it looking dry on top you will over water and cause the plants/seedling to become stressed or kill them all together. Too much water will make it very soggy and you’ll have to squeeze it out otherwise the excess moisture can cause root rot. If you only want to use a small section and not the whole brick it is not that easy to break off smaller pieces.

PROS

  • Great for seed starting in winter
  • It expands a lot 
  • Good alternative soil option
  • Inexpensive and easy to use

CONS

  • Need to be cautious of overwatering
