FoxFarm Bush Doctor Microbe Brew Microbial Inoculant 1-0.3-0.2 | 32oz - Concentrate

Liquid Microbial Inoculant for Root Zone Colonization, 32oz

FoxFarm Bush Doctor Microbe Brew is built around a complex blend of microbial ingredients rather than a conventional NPK load, formulated to encourage rapid microbial colonization at the root zone. The light 1-0.3-0.2 nutrient content sits underneath that microbial focus, and the product is meant to be applied at more than one point across a crop's life cycle.

The 32oz size fits grows already running Microbe Brew as part of an established program.

Key Features & Benefits

• Complex microbial ingredient blend — the primary function of the product, ahead of its light 1-0.3-0.2 nutrient content.
• Encourages root zone colonization — aims to establish beneficial microbes around developing roots.
• Multi-stage application — designed for use at more than one point in the growing cycle rather than a single application.
• Broad growing-system compatibility — works across soil, soilless, and hydroponic setups.

Who Should Use Microbe Brew

Growers focused on building root zone microbial populations across multiple stages of the growing cycle, in soil, soilless, or hydroponic systems, are the fit for Microbe Brew.

Frequently Asked Questions

What is the main function of Microbe Brew?

It's built around a complex blend of microbial ingredients meant to establish beneficial microbes at the root zone, with its light 1-0.3-0.2 nutrient content playing a secondary role. That microbial focus is the reason it's grouped with FoxFarm's Bush Doctor supplement line rather than the core feeding trio.

When during the growing cycle should Microbe Brew be applied?

It's designed for multi-stage use rather than a single application, so it can be worked into the feeding schedule at more than one point across the crop's life cycle. Repeating the application supports ongoing colonization rather than a one-time inoculation.

Does Microbe Brew work in a hydroponic reservoir?

Yes, it's compatible with soil, soilless mixes, and hydroponic systems alike. The microbial blend doesn't require soil biology to function.

What sizes is Microbe Brew available in?

It comes as a liquid concentrate in 16oz, 32oz, and 1gal bottles. Scaling up the size doesn't change the microbial blend or the multi-stage application approach.
