Pre-Mix 5 Liter Buckets

Biobizz Pre-Mix Dry Organic Fertilizer — 5-Liter Bucket

Biobizz Pre-Mix is a dry granular fertilizer made from 100% natural ingredients: organic matter, rock meal, and trace elements. Unlike liquid fertilizers that are diluted in water and applied at each watering, Pre-Mix is incorporated directly into the growing substrate before planting. Once mixed in, it becomes part of the root zone environment, providing a sustained foundation of organic nutrition that supports vigorous vegetative growth, abundant flowering, and improved disease resistance.

The microbially active formulation supports biological life in the substrate. This matters because beneficial microorganisms in the root zone break down organic compounds and make nutrients more available to plants over time — a core principle of the Biobizz organic growing approach. Pre-Mix can be added to any substrate to enhance its nutritional profile and biological activity before use.

Key Features & Benefits

• 100% natural ingredients — made from organic matter, rock meal, and trace elements — no synthetic fertilizer compounds or chemical additives.
• Microbially active blend — supports biological life in the growing substrate, enhancing nutrient availability through natural microbial breakdown processes.
• Dry granular format — mixed directly into the substrate before planting — provides a sustained organic nutritional foundation throughout the grow cycle.
• Supports disease resistance — the balanced organic mineral content and microbial activity improve the overall health and stress tolerance of the root zone.
• 5-liter bucket — compact size suitable for amending substrate for small to mid-size growing setups.

Who Should Use Biobizz Pre-Mix (5 L)

Growers who want to enrich their potting substrate with an organic dry fertilizer before transplanting — particularly those using lightly amended substrates like Biobizz Light-Mix who want to increase the organic nutrient content and microbial activity of the growing medium before the start of the cycle.

Pre-Mix Application: How to Incorporate Into Substrate

Mix Pre-Mix thoroughly into your growing substrate before transplanting. The recommended application rate is printed on the packaging — follow the Biobizz official Nutrient Schedule for guidance on mixing ratios and timing. Pre-Mix is not a standalone growing medium: it should be blended into potting soil, coco substrate, or other growing media before filling containers. Do not apply directly to the root ball or mix after planting.

Frequently Asked Questions

What is Biobizz Pre-Mix?

Pre-Mix is a dry granular organic fertilizer made from organic matter, rock meal, and trace elements. It is mixed into growing substrate before planting to provide a sustained foundation of organic nutrition and to support microbial life in the root zone.

How do I use Pre-Mix?

Mix Pre-Mix into your potting substrate before filling containers and transplanting. The recommended application rate is on the packaging. It should not be applied directly to roots or added after planting — it works by becoming part of the root zone environment before the grow cycle begins.

Can I use Pre-Mix with Biobizz liquid fertilizers?

Yes — Pre-Mix is designed to complement the Biobizz liquid fertilizer range. It enriches the substrate with organic matter and trace elements that support biological activity, while liquid nutrients like Bio-Grow and Bio-Bloom provide targeted nutrition during the grow and bloom phases.

Is Pre-Mix suitable for coco or soilless substrates?

Pre-Mix can be mixed into a range of substrates to enhance their nutritional profile. It works particularly well with Biobizz Light-Mix or other lightly amended substrates where the grower wants to increase organic matter content before planting.

How does Pre-Mix differ from a liquid fertilizer?

Pre-Mix is a dry fertilizer mixed into the substrate before use — it releases nutrients gradually over time through biological breakdown. Liquid fertilizers are applied at each watering and provide more immediate, targeted nutrition. Pre-Mix and liquid fertilizers serve different roles and are typically used together in the Biobizz growing program.
