  • General Hydroponics Ripen (0.5 - 7 - 6), 2.5 Gallon

    A forcing solution, General Hydroponics® Ripen® is a late stage nutrient that can be used to speed up the final stages of fruiting and flowering. Ripen® is particularly useful for outdoor plants where bad weather threatens to ruin a harvest, or for indoor plants suffering from a disease or pest problem to enable at least part of the crop to be salvaged. It will create a strong signal in the plant that it is coming to the end of its lifecycle and needs to fruit or flower, so you will often see the leaves turning yellow as the fruit and flowers grow rapidly. GH Ripen® will ensure that any micronutrients or nitrates being stored in the plant are used, which will improve the taste of the crop. Please note that Ripen® is a complete nutrient and not just an additive, and should be used instead of your nutrient solution for the last week or two of flowering. It is suitable for use in hydro, coco, or soil.

  • General Hydroponics pH Down 8 oz Acid, Case of 12

    To maximize plant growth the pH content of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water or pH unstable media - such as rock wool and gravel products - are used and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.pH Down: Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.
