pH Reducer 100% organic and a valuable tool for successful crops. It is approved for use in organic production by WSDA (Washington State Dept. of Agriculture). A safe alternative to buffer both soil and water. Use in place of highly corrosive acids that are dangerous to handle and can quickly burn a cropís delicate roots. It can be utilized on outdoor soil, soilless media mixes and to buffer the pH of water.
pH reducer has the added benefit of natural Citric acid, which chelates elements and minerals such as nitrogen, phosphorus, potassium, calcium, iron, and others that collect in the soil, during the crop cycle, making them soluble for plant uptake. Furthermore, Citric acid (C6H8O7) bonds to Phosphorus anions (P-), making them soluble and mobile in the rhizosphere and soil solution. This keeps phosphorus, a much needed nutrient, in a form available to plant roots. Citric acid (aka citrate) increases the bio-availability of Phosphorus anions (P-) present in the media. Nutrient uptake is directly dependent on the pH of the solution and the solubility of the nutrients, influencing the ability of roots to uptake all nutrients. By adding citric acid, cations are held in equilibrium.
The buffering capacity is the ability to resist change in pH and is different for every water supply and soil or soilless mix. Bringing about a pH change in a weakly buffered soil or water will require less pH Reducer than in a highly buffered soil or water. Remember that it is better to begin by adding too little pH Reducer than to add too much. DO NOT add other chemicals to diluted pH Reducer when adjusting pH.
Lower pH safely and gradually with the gentle formulation of pH Reducer. Itís ideal for use in any spray equipment, and fertigation, irrigation, drip or hydroponics systems. DO NOT mix concentrates together. Always fill tank ĺ full with water before adding concentrates. Be sure to slowly add pH Reducer to any mix and check with a pH meter or litmus paper until desired pH in reached. It is compatible with other technical materials, including fungicides, however, all product labels must be read to make sure the acidic pH will not affect the performance of the mixture.
Since pH Reducer is acidic, it must first be diluted with water prior to mixing with other nutrients or technical materials. pH Reducer should not be mixed as concentrate or highly alkaline materials. Hard and alkaline water sources will leave residues and mineral build up on tanks, lines and irrigation heads. Flush lines and tanks with a 1% solution of citric acid (1:100) of water. Follow by flushing with water to rise out lines.
pH Reducer can be stored in normal warehouse conditions. It has an acidic pH of 1.5. Always store in original container out of direct sunlight. Do not store below 32o F. Do NOT Freeze. Do not store above 100o F for long periods of time. Refer to SDS for additional information on storage, handling, safety, disposal and shipping.

Application Rates



Frequency / Notes

Hydroponics:acidifying alkaline water

Mix 1 ml per gallon water (For larger applications mix 2 fl oz per 100 gal water)

Measure the pH of your tank water. Add diluted pH Reducer to tank. Wait 15-30 minutes, and test your water again. If pH is not sufficiently lowered, continue to adjust pH over several additions. Check pH every few days to adjust.

Adjusting Growing Media

Mix 1-2 ml per gallon water (For larger applications mix 4 fl oz per 100 gal water)

Take a sample of your soil or soilless mix and test the pH. Add diluted pH Reducer to soil sample and let stand 24 hours. Take another pH reading. If pH is not sufficiently lowered adjust rate accordingly. It is better to slowly adjust soil pH over several waterings.

Hand Watering

Mix 1/2 - ĺ teaspoons pH Reducer per gallon water

Saturate soil with solution.
