BioSafe ZeroTol HC, 1 gal

BioSafe ZeroTol HC — Peroxyacetic Acid Fungicide for Small Indoor Growers

Indoor and hydroponic growers operating in smaller spaces — grow tents, small rooms, or hydroponic setups under 500 square feet — face the same pathogen challenges as larger operations: algae in reservoirs, bacterial contamination of irrigation water, and fungal pressure on plant surfaces. But many commercial-scale sanitation products are sized and priced for large greenhouse operations, leaving small growers with either oversized containers or products not optimized for their scale.

BioSafe ZeroTol HC is a peroxyacetic acid (PAA) bactericide and fungicide formulated with the smaller indoor and hydroponic grower in mind. It provides broad-spectrum control against bacteria, fungi, and algae with no residue after use. The 1-gallon format is practical for growers managing up to 500 square feet of growing space who need effective pathogen control at an appropriate scale.

Key Features & Benefits

• Formulated for small indoor growers — designed for indoor and hydroponic operations with 500 square feet or less of growing space — not oversized for small-scale applications.
• Peroxyacetic acid chemistry — PAA-based broad-spectrum formula kills bacteria, fungi, and algae on contact.
• No residue — peroxyacetic acid breaks down into acetic acid and oxygen after use — no persistent chemical residue.
• For indoor and hydroponic systems — suitable for use in indoor grow rooms, grow tents, and hydroponic systems where pathogen control is needed.
• 1-gallon size — practical 1-gallon format for small-scale growing operations without the overhead of commercial-volume containers.

Who Should Use BioSafe ZeroTol HC (1 gal)

Indoor and hydroponic growers with up to 500 square feet of growing space who need broad-spectrum bactericide and fungicide control for algae, bacteria, and fungi at a scale appropriate for small indoor operations.

ZeroTol HC vs. ZeroTol 2.0: Choosing the Right Product

ZeroTol HC and ZeroTol 2.0 are both peracetic acid based bactericide/fungicide products, but they differ in concentration and intended scale. ZeroTol HC is formulated for smaller indoor growers with up to 500 square feet of growing space. ZeroTol 2.0 is available in larger commercial volumes (2.5 to 55 gallons) and is labeled for edible crops and greenhouse food crop operations. For large greenhouse operations, ZeroTol 2.0 is typically the more appropriate choice. For small indoor or hydroponic grows, ZeroTol HC provides effective control at the right scale. Follow all label instructions for either product.

Frequently Asked Questions

What is BioSafe ZeroTol HC?

ZeroTol HC is a peroxyacetic acid (PAA) broad-spectrum bactericide and fungicide formulated for smaller indoor and hydroponic growers with up to 500 square feet of growing space. It kills bacteria, fungi, and algae with no residue.

How does ZeroTol HC differ from ZeroTol 2.0?

Both products use PAA chemistry and provide broad-spectrum pathogen control. ZeroTol HC is formulated and sized for smaller indoor growers with up to 500 sq ft of growing space. ZeroTol 2.0 is available in larger commercial volumes and is labeled for edible crops and greenhouse food crop operations.

What pathogens does ZeroTol HC control?

ZeroTol HC provides broad-spectrum control against bacteria, fungi, and algae. It kills pathogens on contact using peroxyacetic acid chemistry. Refer to the product label for the specific list of labeled organisms.

Does ZeroTol HC leave residue?

No — peroxyacetic acid chemistry breaks down into acetic acid and oxygen after use, leaving no persistent chemical residue. This makes ZeroTol HC suitable for use in areas that will be replanted or re-used shortly after treatment.

Can ZeroTol HC be used in hydroponic reservoirs?

ZeroTol HC is formulated for indoor and hydroponic growing environments. Refer to the product label for specific use instructions for hydroponic reservoir sanitation, dilution rates, and any requirements for flushing after treatment.
