Question for those that use a neutral media and feed with a complete nutrient solution.
Do you toss the media each season or stretch it with part new mix?
What is your go to mix?


I need to come up with a grow media for onion, leeks, carrots, beets, garlic, potato. Like to get a few seasons out of it if I can, or at least have it be dirt cheap.

Thx
