Dr Cal Herrmann, formerly a senior chemist at NASA, created GHE Ripen General Hydroponics. Dr Herrmann is a partner at GH and still conducts research and product development. GH Ripen gives plants a strong signal that it is coming to the end of its life.
The plant then sends a signal to speed up the ripening process, in a last effort to flower. This type of additive is referred as a forcing solution and is particularly useful when used in cases of a severe infestation of fungi or insects, it allows you to accelerate the natural cycle and get something out of a crop otherwise completely lost. GH Ripen is also good to use if there is a salt build-up, it helps metabolise these residues, which will help plants get back on track and improve the taste of the crop.
Note - GH Ripen - is not designed to be used with any other plant foods and should be used just on its own. When preparing your nutrient solution be careful not mix them together in their concentrated form. Add each part of your nutrient schedule to your tank separately, mixing thoroughly before adding the next component to the mix.
GH Ripen feed rate - 5 - 6 ml/Litre late Bloom.
