Newbie..used too much of Mel's Mix in 4x4
Okay, so I'm not that great with math and noticed that I filled my 4 x4 box to the rim with Mel's Mix. I used 8 cubic feet of each ingredient (with the exception of vermiculite) for this one box and boy did I spend a pretty penny! Any concerns that I should have about using too much mix? Also, b/c I don't have 1/3 vermiculite for this mix...should I worry?
