The safe alternative for adjusting nutrient pHFlairform pH Down is non-corrosive (non HazMat*). This solves the long-standing safety and handling problems associated with regular pH Down solutions:Organic formulation (500g/L citric acid).Much safer to use than phosphoric or nitric acid and more environmentally friendly.Ideal for mail order and distribution: No special freight, handling or storage requirements.Available in 250ml, 1L, 5L & 20LThe working nutrient pH should be checked at the following times:1. When first made.2. After the addition of top-up water or additives – especially if either is highly alkaline.3. In recirculating systems, pH should be checked on a daily basis because the uptake of water and nutrients causes pH to change.NOTE: It is best to adopt a pH maintenance regime that helps prevent pH from getting too high. If pH is left too high for a long period of time, the resultant precipitate is usually not easily re-dissolved. If your pH tends to continuously rise (the most common trend), then at each adjustment, reduce the pH to about 5.0 using pH Down. This will give you a much larger pH “safety” margin than, for example, 5.8.Supplier source: https://erithhorticulture.com/product/ph-down-250ml-81-professional-2/

Growth Technology pH Down 30%Having the correct pH level is an important part in maximising the amount of nutrient that can be uptaken by the plant. If the pH is consistently incorrect it can lead plant dificiencies and even slower growth. Generally most indoor plant require a pH between 5.5 to 6.5, but it can be more specific depending on growing medium and method. CautionThis pH down solution is 30% phosphoric acid. Always handle pH up and down with care. If any of these liquids come into contact with your hands or skin, wash immediately and never mix the two of them directly together.Supplier source: https://erithhorticulture.com/product/ph-down-5l-30-concentrated/

Growth Technology pH Down is a stable solution of 81% phosphoric acid. It is used to lower the pH of your nutrient solution. It is a very concentrated product and a little goes a long way.How To Use pH DownAlways add pH adjustments after you have added all of your nutrients (unless otherwise stated) to your reservoir or watering can, this is because some nutrients and additives can raise or lower the pH.pH Down is a very concentrated liquid and only a small amount is needed to make changes to the pH of the water. As all water is different there is no set amount you need to add. However as a rough guideline we would recommend to test the pH of the water with a meter, before adding any to get a reading then we suggest to start with around 0.25-0.5ml per 10L. Test the pH again to get an indication of the effect it has had and slowly add more until you reach the desired level. pH Down is a very ‘dense’ liquid and needs to be mixed throughly into your water to avoid mis-readings.IMPORTANT – pH Down is an aggressive liquid and can cause skin burns and eye damage. Always take care when handling it and be sure to read the safety advice on the label.Supplier source: https://erithhorticulture.com/product/ph-down-5l-81-professional/

It can be a bit more complicated when growing organically or in soil.There are several ways to check the pH of the nutrient solution in your hydroponic system.The easy way to check pH is to use the digital meters. The most popular type of pH meter for the hobby gardener is the digital pen.You simply dip the electrode into the nutrient solution for a few moments and the pH value is displayed on an LCD screen.The pH meters are very accurate (when properly calibrated) and fast. They need to cared for properly however, or they will quit working.The glass bulb electrode must be kept clean and some are required to be wet at all times. The pH meters are actually very sensitivevolt meters and are susceptible to problems with the electrode.Many of the pH meters on the market have Automatic Temperature Compensation (ATC), which corrects the reading with respect to temperature.On meters without ATC the pH should be checked at the same time of day each time in order to minimize any temperature related fluctuations.The pH meters usually need to be calibrated frequently, as the meters can drift and to insure accuracy you must check calibration often.With most pens, the tip needs to be stored in an electrode storage solution or in a buffer solution and should never be allowed to dry out.Supplier source: https://erithhorticulture.com/product/ph-down-bloom-500ml/

Out of stock
The pH-value of the nutrient solutions For cultivation with hydro and coco it is necessary that the feeding water is set to a certain pH-value. This pH range is around pH 6 (5.8 – 6.2). But small deviations above or below this value are still acceptable. The reason for this is that the feeding water determines the root environment because the hydroponic mediums are neutral and only give support to the roots, they cannot store the nutrient particles. For soil this is different, since it is able to store the nutrients and distribute them to the plant over several days, during which the pH value in the soil itself decreases. The feeding water for hydro and coco cultivation however actually runs along the roots and must at this point contain all substances in the proper concentration required by the plant. That is also why the pH-value must be optimal at the moment of feeding, in order to be able to absorb all nutrients maximally. If the pH is much lower, the roots could be damaged. If the pH is much higher, the plant can no longer absorb all nutritional components. Furthermore, plants like constant pHĀ values, which makes it necessary to check and, if needed, to adjust the pH of the nutrient reservoir for hydroponic cultivation.Supplier source: https://erithhorticulture.com/product/ph-plus-1l/

FOR KICK-ASS FLOWERSPhosphorus and potassium become more essential in the course of the bloom. The goal of blossoming is reproduction, a high quantity of genes (DNA) is created and goes together with a high need of power. The phosphate is used as a building block.Potassium is the key for the movement of water and nutrients from the roots to the foliage. It also controls CO2 absorption and has a significant impact on photosynthesis. From the middle of the bloom phase, or when the bloom is noticeably slack, Phosphorus Plus is given in combination with Bloom Complex. Why not before? Simply, it is not required before this point, the PK levels from the Bloom Complex are fully sufficient. An excessive P and K concentration would hinder the absorption of essential minerals or even cause deficiencies.Use with Bloom ComplexInspire prolonged bloom for the flowersFor indoor and outdoorSupplier source: https://erithhorticulture.com/product/phosphorous-plus-500ml/
