New non-mineral based acids and bases will not add nutrient value like the use of phosphoric acid or potassium hydroxide. They are safer to use as well as compared to mineral based adjusters. This is due to having a zero rating score for all safety categories on the HMIS scale as well as being non-corrosive and non-caustic. This means there are no HazMat fees to ship these products like other pH adjusters. Use Pro pH UP or Pro pH DOWN to effectively adjust the pH of nutrient solutions or irrigation water. Highly concentrated and available in commercial sizes.","brand":"BFG Supply","offers":[{"title":"Default Title","offer_id":50515684852023,"sku":"HGC722006","price":179.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/HGC722006_55662bcd-0135-4aa3-a54f-7c9c92b30af2.jpg?v=1744996784"},{"product_id":"general-hydroponics-ph-control-kit-12-cs","title":"General Hydroponics - pH Control Kit (12\/CS)","description":"\u003cb\u003eGeneral Hydroponics pH Control Kit\u003cbr\u003e4pc - 8oz pH UP, 8oz pH DOWN, 1oz Indicator, \u0026amp; Vial\u003cbr\u003e\u003c\/b\u003eGeneral Hydroponics pH Control Kit contains 8oz pH UP, 8oz pH DOWN, 1oz Test indicator and Vial. pH UP is a base solution formulated using potassium hydroxide and potassium carbonate. pH Down's acid formulation uses food grade phosphoric acid to lower the pH to the proper level.

The maintaining of an optimal pH is essential to maximize optimum growth. The general rule of thumb is that as pH increases the solubility of minerals and nutrients decrease. It is important that nutrients are soluble for plants to uptake and use for growth. The pH of nutrient solution can also affect the bacteria that fix nitrogen for the plant to use. Every plant has optimum pH levels for growth. Below is a table for the ideal pH range for a variety of plants.\u003cbr\u003e\u003cbr\u003eThe HI98118 can be used to measure the pH in soils as well as nutrient solutions.

Customization includes temperature readout in oC or oF, automatic shut off selectable from 8 minutes, 60 minutes or disabled, and lastly the choice of using Hanna's Quick Cal pH\/EC standard or traditional buffers values of pH 4.01, 7.01 and 10.01.\u003cbr\u003e\u003cbr\u003eThe HI98118 features a cloth junction.
