Q.compost tea
I have made a batch of compost tea using 2 cups of fish and sawdust compost, 1 1/2 cups of mushroom compost, 1/3 cup of liquid fish and kelp fertilizer in 5 gals of rainwater. Have aerated it for 48 hours. It smells sour, very yeasty. Is it safe to use? Thanks
If you aerate your tea you can keep for 2 to 3 days.
After 48 hours the diversity of microbes will began to decline.
I have not heard of your combination before so I can't determine a 'shelf life' other then the guidelines above.
