• (x1) Run Off Testing
• (x1) Water Analysis

Nutrient Water Analysis

This liquid analysis determines the exact ion concentrations in mixed fertilizer solutions after dilution in your source water. It reveals whether target ppm levels are achieved and flags hidden sodium, chloride, or carbonate buildup that can impair nutrient uptake.

Recommended use: after formula adjustments or monthly in recirculating systems.

Leaf Tissue Analysis (Plant Tissue Analysis)

A leaf tissue test identifies nutrient levels within the plant itself, enabling precise fertilization adjustments. It helps growers compare actual uptake to feed charts, pinpoint luxury P/K uptake or Ca/Mg deficiencies, and refine nutrient programs accordingly.

Recommended use: as flower checkpoints (e.g. week 3 and week 6) or when visual symptoms appear despite normal runoff readings.

Run‑Off Testing

Run‑Off analysis measures imbalances in EC and pH in your growth medium leachate versus feed. By detecting whether nutrients accumulate or if plants are absorbing what you provide, it helps growers fine‑tune feeding and prevent salt buildup. Ideal for media such as coco, rockwool, or soil.

Recommended use: weekly spot checks during heavy feeding stages or after recipe changes or flushes.

Water Analysis

A water analysis is important for wells because well water is usually high in salts, and levels often change. Even water from municipal sources can change in composition over time so regular testing is important to determine purity and safety.

Recommended use: Quarterly or whenever municipality changes source or before installing expensive filtration

What To Expect: We will ship the appropriate sample holder and accompanying instructions, along with a prepaid return label, if requested, for sending it back to our facility. Test results will be available within 2 to 3 business days after which one of our Cultivation Advisors will contact you to discuss the next steps.
