Who This Is For

  • You are adding biologicals to your hydroponic system because your current powders keep clogging up your drippers.
  • You are pre-treating transplants because your previous crops stalled for a week while the roots slowly established.

What We Found

  • We find this is the best choice for hydro because it actually dissolves instead of settling as sludge in the tank.
  • The concentration is high enough that you only need a teaspoon per gallon to see a visible change in root mass.

What Users Say

  • Users who switched to this blend report that their crops bounce back much faster from accidental dry-back events.
  • People who moved away from liquid microbes tell us they prefer the shelf life and lower shipping costs of this powder.

GreenGro Biologicals Premium Ultrafine Myco

Struggling to give your plants the robust foundation they need for explosive growth? GreenGro Premium Ultrafine Myco is the key to unlocking your plant's full potential by building a thriving underground ecosystem. This powerful, water-soluble blend of mycorrhizae, beneficial bacteria, kelp, and humic acid works synergistically to dramatically improve root health and vigor, ensuring your plants get the most out of their nutrients.

The diverse selection of endo mycorrhizal fungi and beneficial bacteria from GreenGro Biologicals creates a vast network of microfilaments, acting as a natural extension of the plant's own root system. This enhanced network, supercharged with soluble kelp and humics, breaks down and transports nutrients with unmatched efficiency. It's the ideal formula for any hydroponic or soil drench application, suitable for everything from fruits and vegetables to herbs and flowers.

FAQs

What is GreenGro Ultrafine Myco and how does it work?+

It's a soluble blend of beneficial fungi (mycorrhizae) and bacteria that form a symbiotic relationship with your plant's roots. This creates a massive secondary root system that dramatically increases the plant's ability to absorb water and nutrients, leading to healthier and more vigorous growth.

Can I use this product in my hydroponic system?+

Absolutely. This product is specifically designed to be 'ultrafine' and highly soluble, making it perfect for use in hydroponics, deep water culture (DWC), and other fertigation systems without clogging lines or emitters.

How often should I apply Ultrafine Myco?+

For best results, apply during transplanting to inoculate the new root zone. You can also apply it as a soil drench every 2-3 weeks during the vegetative and early flowering stages to maintain a healthy microbial population in the root zone.

What's the difference between this and the Granular Plus Myco?+

The Premium Ultrafine Myco is a soluble powder designed to be mixed with water for drenching or hydroponic use. The GreenGro Granular Plus Myco is a dry, granular product intended to be mixed directly into soil or growing media during planting or transplanting.

Can I use this with other nutrients and supplements?+

Yes, Ultrafine Myco is designed to complement your existing feeding schedule. It enhances the effectiveness of other plant nutrients by improving uptake. It works exceptionally well with other GreenGro products like Pride Lands Veg during vegetative growth and Pride Lands Bloom during the flowering stage.
