#5 is a superior triple-washed coconut and perlite based growing media for
laboratory and professionally controlled growth environments. It delivers the
optimum air to water ratio that is important to professional growers.
with all coconut-based growing mediums, it should be saturated with calcium
prior to planting. The reason behind this is because coconut coir “holds onto”
calcium instead of leaving it available for the plant. By saturating the coconut
fiber prior to planting you are allowing the coconut fiber to become “full”
making it easier for the plant to obtain the necessary calcium for optimum
plant growth. Cal-Mag Extreme is a good source of calcium and works very well
for this application.
