Microbe Life Hydroponics Feeding Schedule

About Microbe Life Hydroponics

Microbe Life is a biologicals house. Photosynthesis Plus is the flagship — a consortium of bacteria and archaea that improves nutrient availability and can be used as a root drench or a foliar — and Root Dip, Bloom Yield Enhancer and Nourish-L fill in the rest of the cycle.

Like all live products, these want reasonable handling: don’t mix them into a tank with a strong oxidiser, don’t let them sit in the sun, and use them within a sensible window of opening. Do that and they slot into almost any base programme without conflict.

The feed chart

Microbe Life Hydroponics feed chart

Application chart (table)

Microbe Life publishes this chart only as a flattened image, with no text layer or PDF to extract, so the tables below were transcribed by eye directly off the image above at full resolution, then independently re-read a second time before publishing. Reproduced exactly as Microbe Life prints it; a dash means the chart lists nothing for that product at that stage.

Photosynthesis Plus has its own separate foliar dose row on the chart, printed alongside the standard root/soil drench row above it. Three of that row's cells (Vegetative, Week 2, Week 4) are highlighted on the manufacturer's own chart as an "Alternative Dosing for Foliar applications with Photo Plus products" rate of 1.35oz./1 gallon (10mL/1L) — a stronger mix than the 1-2oz. rate used the other weeks. Both rows are reproduced exactly as printed, including a few cell-to-cell differences in how the manufacturer writes the metric dose (e.g. "3ml/1L" at Week 1 on the drench row versus "3ml/L" at Week 1 on the foliar row for the same US measure) — these are the chart's own inconsistent typesetting, not a dosing difference, and are kept as printed rather than normalized.

Terps Plus dosing schedule

Cumulative application % 5% 15% 30% 50% 60% 70% 75% 80% 85% 90% 93% 95% 98% 100% — —

The chart's own "weekly % of total application" row and its own "cumulative application %" row do not quite agree at weeks 12 and 14: the weekly row prints 3% for both weeks, while the cumulative row's own week-to-week change works out to 2% for both. Both rows are reproduced exactly as Microbe Life prints them (this is rounding in the manufacturer's own chart, not a transcription error) rather than silently corrected.
