General Hydroponics Ripen
Late flowering / forcing solution :
The industry standard final phase nutrient.
Ripen ® is the best-selling GHE product worldwide for a good reason:
Using Ripen instead of a two week water “flush” means stronger taste, more active principles, and up to 10% more yield.
Ripen works by providing high quality, balanced nutrition when flowers and fruits are finishing their flavour development and growth.
Ripen is an extremely effective way to eliminate nutrient excesses in your crops.
There is no magic way to make excess nitrate or chlorophyll (the main cause of most taste issues) disappear - they have to be metabolised, and Ripen helps your plant do so in a way that generates useful yield, AND improves taste.
Ripen acts in 3 ways:
● It sends a strong signal that the plant is coming to the end of its life, accelerating the ripening process.
● It forces the plant to strengthen its defences, increasing essential oil and active principle production.
● It provides the complimentary mineral salts the plant needs to metabolise nitrate or microelement build ups in easy to assimilate form.
As a “forcing solution“ Ripen can be used whenever you need to control or enhance ripening, and to maximise yield and flavour intensity at the end of the flowering/fruiting phase of all annual plants and flowers.
Outdoors and indoors Ripen enables you to quickly harvest a crop before it is spoiled by cold and damp weather. Ripen also allows you to harmonise the end of the grow cycle by speeding up the ripening of the slowest plants or varieties. And in case of a severe infestation of fungi or insects, it can accelerate the natural cycle and help you recover something from a crop that would otherwise be entirely lost.
At high EC, expert growers can use Ripen to manipulate water stress to maximise active principal concentration, and minimise splitting in soft fruit culture.

When to use Ripen and how long for:
Substrate, species, strain and conditions affect when to use Ripen and how long for, but, whatever the situation, your plants should always be your guide. For example, if the leaves on your crop are dark green add around two days of Ripen usage to the numbers below; if they are already yellowing, remove two or more.
The universal rule for Ripen is: apply until leaf yellowing occurs and / or ripening is satisfactory.
How to use:
Hydroponics (recirculating) or run to waste etc: Replace old nutrient solution with pH adjusted water, add Ripen and mix well.
In soil: Apply as normal in pH adjusted water.
In high drainage substrate (e.g clay pebbles or bare root): Use Ripen for around 10 days (start 12 days before harvest) - match your last EC (up to 5ml/L, max EC 2.6).
In medium drainage substrate (e.g coco-perlite mix): Use Ripen for around 15 days (start 17 days before harvest) - match your last EC (up to 5ml/L, Max EC 2.6).
In low drainage substrate (e.g soil or potting compost): Use Ripen for around 21 days (start 23 days before harvest) - match your last EC (up to 4ml/L, max EC 2.0).
Expert growers can use Ripen to manipulate water stress to maximise active principal concentration, and minimise splitting in soft fruit culture: target EC 2.6mS in hydro and target EC 2.0mS in soil.
To promote sugaring and give your crop a final flavour boost, we recommend using GHE FloraKleen® for a maximum of two days in hydroponics, and five in soil. Flushing more than this after Ripen reduces crop quality and risks water saturation.
Pro tip: Using FloraKleen for two days before Ripen to condition and break down mineral salt build ups in your substrate delivers Ripen results even faster.
