How To know When A Fertilizer For Cannabis Expires?
Most fertilizer brands do not have an expiration date, how do you know when a product expires? It is true that the vast majority of fertilizer brands do not have expiration dates, for the simple reason that it is not possible to say exactly on what day a product expires. It is not the same to say “expires on May 10, 2014” that “better to consume before May 10”; The first implies that the product will deteriorate from that day; The second, that from that date the product can start to lose properties, but that can be continued using (it is as with the subject of yogurts: they can be consumed after the indicated date).
As a general rule, if the bottle is closed, the product can be maintained for about four years in good condition; some organic products possibly a little less. Once a container has been opened, it must be consumed within one year.
If you have an open boat for more than two years, chances are it is already in poor condition.
The environment where the product is stored is also heavily influenced. Care must be taken not to expose the products to full sun or store them in places that are too hot or too cold. The minimum temperature that has to have the place where they are stored is of about 5 °. Below that temperature, a reaction called crystallization is most likely to occur and, therefore, the liquid becomes a solid paste; that is, unusable.
All well-known brands work with lot codes. These numbers are usually printed or marked on the bottles or caps and indicate, among other things, the date of manufacture and not the expiration date.
If there is a problem with a product, we recommend contacting the manufacturer, who will ask for the batch code and will be able to detect when it was manufactured to find the fault if there was one and to find a solution to the possible manufacturing problem; this is called traceability, and all manufacturers are required by law to implement it in their production system.
We recommend you always shop in stores that have a lot of movement and have not had the product for months or years on the shelf. Many times the fertilizer has been waiting for a long time to be bought and all these calculations that we have just indicated are of no use, because we do not know since when it has been in the store (and how long the distributor has had before). For this reason we are advocates who at least print the date of production on all fertilizer, but of course, this is contrary to the commercial interests of many.
