ah very nice, ive been looking around for humic acid but i cant find any in my local stores.
do you by chance know the benefits of having a fungal tea vs. a bacterial tea? i cant seem to tell when my teas are fungal.
Without a $1,500.00 microscope you can't tell. If you're using earthworm castings then you're good to go and your compost teas will be balanced across the entire micro-herd - bacteria, fungai, nematodes, protozoa, et al.
Bacteria is very easy to grow in a compost tea. Fungai don't increase in numbers but what they can do is to increase in length. It's no uncommon to have 100,000 fungai strands up to 6' in length in 1/4 tsp. of the tea.
The best way to get the fungai up and running is the addition of kelp meal, (Maxicrop works well too) and most importantly the liquid fish products that are produced by enzymes (fish hydrosylate). You do not want to us the standard 'Alaska Fish Emulsion' or related products. You won't have any problem finding it - look for the words 'enzyme' and/or 'hydrosylate'
If you're trying to push out fungai then leave the molasses out of the mix. The carbohydrates feed the bacteria which consume the food and explode by reproducing and limiting the foods needed by the fungai. Even when you do use molasses you only want to add 1 tsp.
per 5 gallons of water
Here's a 'kind of' or maybe it's a 'sort of' guide for brewing for specific microbial goals. Assuming that you're using an aquarium heater in your tank and you're running the tea at 70F, then a high(er)-fungal tea will be ready in about 12 hours. That is when the fungai have increased in length by huge numbers.
At 18 hours the bacteria are definitely dominating the culture in the tank. Bacteria will dominate until you hit about 36 hours and then the protozoa are up and running and the bacteria have faded substantially for lack of food.
If you're batching out a tea for use as a soil drench then you're probably best to use it around 15 hours - again assuming that you have the water temperature under control. Aquarium heaters are chump-change.
If you're wanting to brew a batch of compost tea to use to wipe out (once and for all) powdery mildew then I would be spraying the tea after 12-14 hours.
With the addition of the fish enzyme product, kelp (or some kind of seaweed product) and pure humic acid you'll end up with some major levels of fungai from the earthworm castings.
The pure humic acid at BioAg.com is NOT derived from Leonardite - thankfully. Their product is so concentrated that you only use 1/8 tsp. per gallon as a foliar spray. Double that amount for brewing tea.
