How to store Mega Crop?

[Antonio Bandido]

Hi Peeps,
I have a big bag of Mega Crop which I have split into 3 but it seems to be doing its own thing in these bags (getting moist and sticky) as I have so much and only need a little, does any one know the best way to store? (i bought a 10kg bag and still have around 9kg left)

Many Thanks...AB

In something completely airtight. Most plastic bags etc are not. Possibly a decent quality bucket with snap on lid. Or use a bunch of mason jars, then they are already divided up into smaller portions ready to go.
