PRO-MIX® HP® BIOFUNGICIDE™ + MYCORRHIZAE™ is a high-porosity, peat-based growing medium designed to ensure optimum growth by providing excellent drainage, high air capacity, and low water retention. Ideal for growers requiring watering flexibility and adaptability to varying crop seasonality, it is formulated with fibrous Sphagnum peat moss and a high percentage of coarse perlite.

This advanced medium contains Mycorrhizae™, a beneficial endomycorrhizal fungus that improves plant resistance to stresses like transplanting, nutrition deficiencies, and drought, while enhancing crop vigor, plant quality, and the quantity of flowers or fruits. It also features Biofungicide™, a Bacillus bacterium that forms a protective shield around plant roots, serving as a barrier against root rot pathogens and promoting healthier, more uniform crops with vigorous root systems.

PRO-MIX® HP Biofungicide™ + Mycorrhizae™ Features:

  • 65-75% Canadian Sphagnum Peat Moss – A premium base for moisture retention and structure.
  • Horticultural-Grade Perlite – Improves drainage and aeration for healthier root systems.
  • Mycorrhizae PTB299 (Glomus Intraradices) – Boosts nutrient and water uptake, enhances stress resistance, and promotes overall root and plant health.
  • Biofungicide PTB180 (Bacillus Subtilis) – Colonizes developing roots to suppress disease-causing organisms and protect plant health.
  • Dries out more frequently than general-purpose peat‑based mixes
  • Well suited for low-light and high-humidity growing conditions
  • More difficult to overwater crops

Cut edges like a pro
Style: 9" 2T Cutting Blade
Better, much better than the OEM yellow and black brand. This has an all metal guard and the blade does not bind when it comes into contact with concrete. I have used it all summer for edging two commercial properties and my own lawn, it’s still turning and cutting with ease. Being all metal adds weight but the trade off over fragile plastic is worth the durability.

OK for light duty use only
Style: 9" 2T Cutting Blade
Not very strong or robust. Does fit my power head properly. Only recommend it for occasional, light duty use.

These work for the Worx trimmer WG928
Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.
