Misplaced a bunch of myco and found it when digging out the snowblower.Temperature was low of 20 degrees-is the myco still viable?I put it in warmer temp right away.Also when figuring crosses is it best to use the heavier or more desired qualities as the female recipient or the pollinator?

VAM Mycorrhizal inoculant should always be stored away from light and temperature extremes. It's dead now.

If you were growing the male only as a pollinator, and inoculant is in short supply, bone up on the female. Males pass traits onto their progeny, but not Myco.

That said, when selecting a seed to grow, people expect the male half of a cross to have performed.

VAM should only be purchased from date coding manufacturers. No date, take your business elsewhere.

Myco is like milk. Ask your wife. LOL

Does that pertain to granular Myco? I hope that isn't a stupid question.

Read this document well. Live VAM spores must contact the host plant roots to work. Age is our enemy. Pumpkin SEEDS store better frozen. VAM SPORES do not.

Conclusion: Spores remain infective after 16 months of storage with temperature conditions varying from occasional freezing to reasonably hot.

BUY FRESH, USE WITHIN 16 MONTHS, STORE AWAY FROM LIGHT AND TEMP EXTREMES. Spending the summer under a tarp isn't great. Finding it again while digging out the snow blower is even worse.

I'm really glad to get a time limit also with expiration.It even makes a difference when you order the myco as far as not ordering it now where it might get too cold in transit plus adding extra months toward the expiration.So what vendor do you feels gives the best value and quality.Yes I did about puke when I found it in our enclosed porch,didn't tell the better half.
