Sold as a 25lb bag, 80 per pallet, acidic 290 lbs. CCE, no urea, ships hazardous.

Key Features & Benefits

• Manages irrigation water alkalinity — conveniently, as part of the fertilizer application itself.
• Contains Peracid — pHLow products differ from other Peters Excel products, combating alkalinity differently.
• Black Iron chelate included — supports iron availability alongside the pH-management chemistry.
• Acidic 290 lbs. CCE, no urea — a strong acidifying technical profile suited to high-alkalinity water.

Who Should Use Peters Excel pHLow 19-11-21

This fits growers working with consistently high-alkalinity irrigation water who want a fertilizer that manages that alkalinity directly rather than relying on a separate acid injection system.

About Peters Excel pHLow

Peters Excel pHLow is manufactured by ICL Growing Solutions as a water-soluble fertilizer sub-line specifically engineered for hard, high-alkalinity water conditions, using Peracid chemistry distinct from standard Peters Excel formulations.

Frequently Asked Questions

When and how is this fertilizer applied?

Apply it as your regular water-soluble feed for crops irrigated with high-alkalinity water, since it's designed to manage that alkalinity conveniently through the fertilizer application itself rather than a separate treatment step. Follow label dilution rates for your specific water alkalinity level.

What makes pHLow different from other Peters Excel products?

pHLow products are different from the other Peters Excel products because they contain Peracid and combat alkalinity in a different manner. That distinct chemistry is what sets this sub-line apart within the broader Peters Excel family.

Does this product have shipping restrictions?

Yes, this pHLow formulation ships hazardous, so confirm your shipping method can accommodate that classification before ordering. Its acidic 290 lbs. CCE profile is what drives that hazardous shipping classification.

What does the acidity rating mean for water management?

This formulation carries a rating of acidic 290 lbs. CCE with no urea, a strong acidifying profile that growers use to plan how effectively it offsets high-alkalinity irrigation water. That strength is specifically why it's positioned as an alkalinity-management product rather than a general-purpose feed.

What size and packaging is this listing?

It ships as a 25lb bag, supplied 80 per pallet, matching its acidic rating of 290 lbs. CCE. That volume suits commercial greenhouse operations managing consistently high-alkalinity water.
