THE GROWER'S REFERENCE
A little measuring.
A lot of growing.
Find your plant's guide. Check your product's rate. Then take it to the garden.

KEEP THIS BY THE WATERING CAN
The one-gallon reference.
Rates below are per gallon of water. Match your plant's stage and follow the current label on your pack for crop suitability and application.
A teaspoon and a tablespoon are different measures. Kelp uses a teaspoon; Veg, Bloom, Incredible Bulk, and King Krustacean use a tablespoon. Measure liquids in mL.
Microbes
Introduce the living biology.
1–3 mLper gallon · each watering
Shake well. Add Microbes to the water first, then your Veg or Bloom. Use through the growing stages.
Product & directionsVeg
Feed the leafy-growth chapter.
¼ tablespoonper gallon · each watering
Use during vegetative growth. For a crop that goes on to flower or fruit, move to Bloom as it enters that stage.
Product & directionsBloom
Feed the flowers-and-fruit chapter.
¼ tablespoonper gallon · each watering
Start at ¼ tablespoon. Increase to ½ tablespoon per gallon at peak flowering as directed on the label. Use on label-recommended crops.
Product & directionsStages, not a universal week number. A basil pot and a fruiting tomato have different jobs to do. Keep the plant's growth stage, growing medium, and existing nutrition in view.
WHEN THERE'S A REASON TO ADD MORE
A purpose for each power-up.
These are optional additions with different roles. Choose the ones that fit your plant and program; the list is not a recipe for mixing every product together.
Each watering during flowering & fruiting. Gradually increase for peak flowering as the label directs.
Root drench only. Do not use as a foliar spray.
Each watering, all growing stages. Dissolve in water and apply as a soil drench.
Use a teaspoon measure for this one.
Each watering, all growing stages. Apply to soil or use in hydroponics according to the label.
Prepare a fresh mix. Check compatibility with existing inputs.
Soil: each watering. Foliar: 5 mL per gallon once weekly. Always dilute; do not store diluted product.
Contains boron. Use only on label-recommended crops.
Every 1–2 weeks in active growth; every 2 weeks for flowers, houseplants, and herbs. Shake and dilute. Foliar: 2–3 mL per gallon; test a small area first.
Do not mix with mineral fertilizers. Use a separate application.
THE SMALL DETAILS MATTER
Mix with intention.
Use it fresh.
Keep the label close, especially when your routine includes more than one input.
- 01
Measure the water first.
All rates here are for one gallon. Measure the actual water volume and use the correct spoon or mL measure.
- 02
Microbes goes in first.
Shake the bottle, add to the water, then add Veg or Bloom. If pairing Microbes with Phishy, Microbes still goes first.
- 03
Check before combining.
Follow each label's mixing directions. Keep Phishy separate from mineral fertilizers. A jar test does not override a product's mixing restriction.
- 04
Make what you'll use.
Do not store diluted Microbes, Vitamin Sea, or Phishy. When tank-mixing Bloom with biologicals, mix less than four hours before use.
This is a quick reference for current Growganica products. The directions on your pack govern application. A crop guide adds growing context; it does not replace the product label.
