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.

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

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.

Fertilizer Analysis

This fertilizer test will give a full NPK analysis showing you exactly where your primary nutrients are at. It will also show seconday nutrient elements like calcium, magnesium, and sulfur as well as micronutrients to help ensure your fertilizer has the perfect nutrient balance. It will also reveal unwanted salts so you can match your feed chart exactly and prevent over-feeding or under-feeding.

Recommended use: Before adopting a new nutrient line or if leaf tissue shows burn or deficiency despite “perfect” feed rates

Soil Analysis

A complete soil or soilless medium test assesses a plant’s ability to absorb nutrients and helps craft ideal irrigation and amendment plans. It evaluates pH buffer capacity, fertility, cation exchange capacity (CEC), and harmful salt levels, and supports testing of coco fiber, peat moss, and composted forest materials.

Recommended use: when starting a new batch of soil, or between runs when re‑amending living media.
