GreenDream A+B runs much cleaner than other 2-part nutrients and requires a lot less pH maintenance!

GreenDream A+B is formulated from high purity mineral salts and chelated trace elements:
GreenDream A+B is very highly pH buffered compared to other nutrient brands. A high pH buffering capacity is a huge advantage because it ensures minimal initial and ongoing pH adjustments are required, especially where high alkalinity make-up water is used. This feature is extremely beneficial because a lack of pH control is a common cause of nutrient failure and plumbing blockages. As a rule-of-thumb, a high quality ‘bloom’ formulation should require virtually no initial pH adjustment, even when used with high alkalinity water. This means that after dilution with a range of make-up waters, the pH should always fall well within the range 4.5 to 6.5. However, many brands fail to offer this feature.
