How to expand compressed coco blocks?

Whats buffered coco? And whats the difference between un-buffered and buffered coco?

In simple words, Buffering is the process by which we avoid nutrient-lockout by the grow media, which impacts nutrient availability in the root zone. By buffering, you stabilize the grow media by modifying few aspects of the media such as pH or ability to hold nutrients. This means that they attract what are known as cations. Cations are positively charges ions. The sum total of negatively charged ions are known collectively as the cation exchange capacity or “CEC”. Knowing the CEC of a media will let you know how much of any particular nutrient the media can absorb before it is leached out. It is important to know however, what the nutrient needs of your particular crop are before setting about adjusting the CEC of any media.

Is buffering same as rinsing?

The words “buffer” and “rinse” in regards to coco coir are sometimes used synonymously. It should be noted that simply rinsing coco coir with water, will not serve to buffer it. Rinsing the coco coir may well remove some of the water-soluble salts that are in it, but it will not by itself alter the CEC of the coir. Additional nutrients will need to be added in order to do so.

Can I reuse coco coir?

Many growers, in an effort to save money, may consider re-using coco coir media, as it holds up fairly well to most growing conditions. Coco coir loses to some degree, its ability to hold water and nutrients after it has been used through an initial growth cycle. While we recommend reusing in your garden, definitely not for cash-crop cultivation.
