South Cascade Organics SLF-100 | 5gal - OMRI Listed

Enzymatic Salt-Breakdown Formula for Hydroponic Systems, 5gal

Mineral salts from fertilizer and hard water build up steadily in hydroponic reservoirs, drip lines, and soilless media, and left unaddressed that buildup restricts flow and can lock out nutrients a plant would otherwise take up freely. South Cascade Organics SLF-100 is an enzymatic formula built specifically to break that salt buildup apart, going to work in the reservoir or media rather than masking the problem.

This 5gal size suits a commercial operation running multiple hydroponic systems that goes through system-maintenance product quickly enough to justify a single larger container over smaller jugs.

Key Features & Benefits

• Enzymatic Salt-Breaking Formula — targets mineral salt buildup in reservoirs, drip lines, and soilless media.
• 100% Organic and OMRI Listed — certified for use in organic production.
• pH Neutral — does not shift reservoir or media pH when applied.
• No Added NPK — works as a cleaning and maintenance formula rather than a fertilizer.

Who Should Use SLF-100

SLF-100 fits growers running recirculating or drip hydroponic systems who need to keep salt buildup from restricting flow or interfering with nutrient uptake, as well as soilless-media growers doing routine system maintenance between crops.

About South Cascade Organics

South Cascade Organics, LLC builds its catalog around SLF-100, an enzymatic formula marketed for breaking down salt buildup in hydroponic and soilless growing systems. The company's own product materials describe SLF-100 as a commercially proven formula with roughly 18 years of use behind it.

Frequently Asked Questions

How does the enzymatic formula break down salt buildup?

SLF-100 uses enzymes rather than acids or chelating agents to work on mineral salt deposits that accumulate in reservoirs, drip lines, and growing media over repeated feeding cycles. Because it works enzymatically rather than through a strong pH shift, it's formulated to stay pH neutral while it works.

How do I use SLF-100 in my system?

Add SLF-100 to the reservoir or apply it to growing media per the label's dilution rate, and let it work through the system's normal circulation or watering cycle. Regular use between feeding cycles helps prevent buildup from accumulating in the first place, rather than only treating it after flow is already restricted.

Will SLF-100 add any nutrients to my feeding program?

No, SLF-100 carries no added NPK, so it functions as a system-maintenance product rather than a fertilizer. It's meant to be used alongside an existing nutrient program, not in place of one.

Is SLF-100 safe for organic production?

Yes, SLF-100 is 100% organic and OMRI Listed, meaning it's certified for use in organic production systems. It's formulated to stay pH neutral, so it shouldn't require a compensating pH adjustment when used at the labeled rate.

How is a case-pack size different from a single unit?

A case-pack simply bundles multiple individual containers together for growers who go through SLF-100 regularly and want to order in bulk rather than reordering single units. The formula and dilution rate are the same regardless of case size.
