Mycorrhizae Question

I want to build a Super Soil & the base organic potting soil w/ coco fiber & Mycorrhizae. I’m discovering it’s really hard to find with that combo, so I want to add it in myself.

I ran across the following Mycorrhizae product & want to know your opinions on it if you have used this brand or similar. How much to add per gallon of soil, etc Any recommendations & help is much appreciated :hugs:

This is the one I use. It gets added to my soil mix then when I transplant I sprinkle some down inside the hole before I put the plant in. I’ll follow the measurements suggested on the back of the bag for usage.
Every time I top feed with it mycelium pops up

Promix offers a mix with mycorrhizae. I used it as my base last year. I also use dynomyco.

Kool I’ll try to find that too. Here lately it’s been hit or miss with stuff being able to even be "delivered to my area":woman_facepalming:t3:

Do you know what the shelf life is? These products are much cheaper per ounce if you buy large amounts, but I don’t want to buy, say, 2 lbs and find it’s gone dead before I can use it all.

I go through a bag roughly every 4 months

Promix Premium potting soil has all that. I believe the bag with pink and blue color. It’s a soil based potting mix with coco and with myco.

Do you use it only when you move seedlings to a pot, or do you apply more later?

I wonder if it’s better to distribute it throughout the soil or to apply a concentrated amount in the plant’s immediate vicinity.

I can understand that 'cuz bagged soil isn’t the best packaging. With moisture inconsistency, shelf life, etc. I dunno

I mix in 4 scoops of mykos with 5 gals of soil. Then when I transplant I’ll sprinkle some down inside the hole. I also add 2 scoops in when I’m top dressing.

To my understanding it has to come into contact with the roots to work. That’s why I put it in my soil & hole then top dress with it. It holds moisture so don’t pile it around the stem or it will rot :person_facepalming: learned that the hard way

I use extreme mykos and trifecta Mycorrhizae together in promix bx. Probably only need one or the other but I use both.

Me three… :wink:

I use the Mykos and last year this year for the first time I used Great White mainly in a “Tea” to water with but I did put it dry into the holes when my seeds popped when putting in solo cups…
yes I agree probably overkill but I had Mycos first and wanted to try the Great White too so…?
