General hydroponics ripen, is a liquid that is used as a catylst that speeds up the rate in which your plant reacts with the oxygen and nutrients surrounding it. General hydroponics ripen basicly forces the plant to speeds up its ripening process hence the name "Ripen". This is particularly useful if you have only a certain amount of time to produce your crops by, and also increases the amount of crops you produce overall. It is only possible to use Ripen for 2 weeks maximum prior to desired harvesting date. General hydroponics ripen has also been found to be beneficial in producing additional essential oils in plants.
