Still Good One Season Later

[NugPufr]

I still have some of the following dirt left over and I was wondering if it would still be good next summer?

1 pack of the 2.1 (5 LB) master mix

6 to 7 gallons of coco coir

6 to 7 gallons of soil, Organic. dr earth is good,miracle grow organics choice is cheap n decent.organic soil ,aint gotta be awesome.

5 gallons of castings

5 gallons of perlite.

yup, stay with 6 gallons and it should be fine with quality water and calmag hits here n there. cal mag+ from go works fine. mix it now and prep it,and it'll be fine by then kept inside. or keep stuffs and make a month and a half prior to planting.

breaking down old soil is all I think about. If you are talking new pot virgin soil it will keep indefinately and only improve with age.
