Maintain Perfect pH Levels - the Organic Way

Bio pH- is an organic pH regulator that works to ensure that acidity / alkalinity levels in the substrate remain optimal, for the absorption of nutrients and for the health of beneficial microorganisms. Bio pH- contains citric acid, a powerful natural pH adjuster that boosts populations of beneficial bacteria and fungi, promoting all-round healthy growth and development.

All BioBizz products encourage beneficial microbial activity in the root-zone. This increases yield and root-health. For a really flourishing microherd we highly recommend using Ecothrive Neutralise to avoid the chlorine/chloramine in tap water from inhibiting, or even killing, the friendly microbes, plus a quality beneficial inoculant such as Ecothrive Biosys with BioBizz products. For an extra kick, try Ecothrive Charge too!

How BioBizz Bio pH- Works

BioBizz Bio pH- raises the pH of your nutrient solution when needed. This facilitates rapid growth by maintaining an optimal balance between acidity and alkalinity. Bio pH- achieves this without the aid of aggressive man-made chemicals, making it compatible with fully organic nutrient regimes. If pH levels fall out of range, the effects will lead to deficiencies that will show themselves throughout the plant, causing stress, stunting growth rates and reducing yields. Use BioBizz pH products to ensure that this never happens!
