This one's worth the trip to the store.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

PRO-MIX HP MYCORRHIZAE is a growing mix built for growers who want consistency across large batches, whether that's a greenhouse operation, a serious hobby grow room, or a commercial hydroponic setup. This 3.8 cubic foot bag has moisture control built in, which helps buffer against the swings in watering schedule that can stress out plants, and it's formulated to hold up well in low-light growing conditions and high humidity - the kind of environment where lesser mixes get soggy or moldy.

The HP Mycorrhizae designation points to what's mixed into this blend: mycorrhizal fungi that partner with root systems to improve nutrient and water uptake, giving plants a stronger foundation from the start. It's suited for hydroponic use, making it a fit for growers running soilless or semi-hydro systems who still want a substrate with body and buffering capacity. Made in Canada by PRO-MIX, a name growers already know for consistent growing media.

  • Approximate weight: 65 lbs

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
