Peters Professional 17-3-17 Peat-Lite Neutral Cal-Mag Fertilizer | 25lb (80/PL)

25lb Neutral pH Peat-Lite Cal-Mag Fertilizer, 17-3-17

Growing media pH can drift with every feeding unless the fertilizer itself is chemically neutral, and most all-purpose formulas aren't. Peters Professional 17-3-17 Peat-Lite Neutral Cal-Mag Fertilizer produces a nearly neutral reaction to help maintain steady pH in growing media.

Sold as a 25lb bag, 80 per pallet, basicity 27 lbs. CCE, no urea.

Key Features & Benefits

• Nearly neutral reaction — helps maintain steady pH in growing media.
• All-purpose formulation — for constant, balanced nutrition.
• Ideal for Water Types 1 and 2 — matched to lower-alkalinity irrigation water.
• Contains calcium, magnesium, and other minor elements — rounds out the 17-3-17 base ratio.
• Basicity 27 lbs. CCE, no urea — a mild, low-basicity technical profile.

Who Should Use Peters Professional 17-3-17 Neutral Peat-Lite Cal-Mag

This fits growers on low-alkalinity Water Types 1 and 2 who want a nearly neutral, all-purpose feed that won't push growing media pH in either direction over repeated applications.

Frequently Asked Questions

Why does this formulation matter for growing media pH?

It produces a nearly neutral reaction to help maintain steady pH in growing media, unlike acidic or basic formulations that shift pH over repeated feedings. That neutrality is the main reason growers on low-alkalinity water choose it.

What water types is this fertilizer designed for?

It's ideal for Water Types 1 and 2. Because it's a neutral formulation, many growers use it specifically in low alkalinity water.

What does the calcium and magnesium content add?

It contains calcium, magnesium, and other minor elements alongside the 17-3-17 base ratio. Those additions support the all-purpose formulation's constant, balanced nutrition goal.

What does the basicity rating tell me?

This formulation carries a basicity of 27 lbs. CCE with no urea, a comparatively mild technical profile among Peters Professional formulations. That low basicity is consistent with its role as a pH-neutral, all-purpose feed.

What size and packaging is this listing?

It ships as a 25lb bag, supplied 80 per pallet, matching its low basicity rating of 27 lbs. CCE. That volume suits commercial greenhouse feeding programs on low-alkalinity water.

How and when should this fertilizer be applied?

Feed it continuously through irrigation at each watering rather than dosing occasionally, since its neutral reaction is designed to hold pH steady over repeated applications. That consistent timing matters most on low-alkalinity Water Types 1 and 2, where the neutral formulation does its best work.
