How to Make Compost Tea

Hi Im Tricia an organic gardner.
I’m here at the Peaceful Valley warehouse facility and today
we’re going to be brewing up some biologically active compost tea. This is a hundred gallon compost tea
brewer from Growing Solutions and these large brewers range in size
from ten gallons up to five hundred gallons and a very well suited for use
on farms, vineyards, orchards, market gardens and
golf courses. The first step is to attach the hose
and fill the tank up to the gallon marker. Make sure all of your brewing equipment
is thoroughly cleaned and only use potable water. These brewers are easy to use and designed
for heavy duty use. If your using city water let it aerate for about thirty minutes
to dissipate all the chlorine because the chlorine will kill your good microbes. Add some food for the microbes. I like this Compost Tea Catalyst since its specially formulated to promote diverse microbal growth without simple sugars which can promote the growth of harmful bacteria. The screens that come with the growing solutions
compost tea brewer are easy to fill and easy to clean. Use a high quality compost, here at Peaceful Valley we use a biodynamic
compost made at Fulcrum Farms here in Grass Valley. Fill the screen up until you see an inch of screen. Install the holding tray so that this little groove is facing back and will fit on this little lip. Slide the screen in to the aerating water, just add the aerating stones into each one
of the screens. Put on the lid and let it brew for twenty four hours. After your tea has brewed you can add a little bit of water soluble fertilizer, but your compost tea will benefit your plants just as it is. So brew some tea and grow organic for life.

  1. the diffuser stones cannot be cleaned and become great places for 'bad' bacteria to grow. You should not use them.

  2. What about chloramines in the water? You can't vent off like chlorine! Chloramines will kill your organisms. Rain Water or spring water makes better sense!

  3. You're right, rain water and spring water would be superior water sources, unfortunately not everyone has access to those sources in the summer. Chloramines can be significantly lowered by the use of an active carbon filter. Sunlight and aeration are also somewhat effective.

  4. The catalyst contains seaweed extract, humic acid and mineral powder, an array of select botanical ingredients and no simple sugars.

  5. will the foods in the tea only promote the fungi in the soil? when you say selected botanical ingredient, could you be more specific?

  6. It should be any of the aerobic microbes (fungi, bacteria ect.) present in the compost. Unfortunately I can't be more specific on the botanical ingredients, the recipe, like that for Coke, is a secret 🙂

  7. Since stones are always under positive pressure and get plenty of air the chances of them supporting anaerobic bacteria are minimal. They should be cleaned between use, and can be bleached if this is a big concern. They will become plugged and ineffective before the bacteria become a factor.

  8. Use the aeration for an hour before adding the compost. The chlorine will gas off quickly. If your city uses something other than chlorine, such as chloramine, consult the utility department for advice. Fluoride may be a bigger problem, as it blocks calcium uptake to plants. If you have problems with blossom end rot in tomatoes or peppers this is a good usual suspect.

  9. The browning may indicate organic matter from algea growth and death. It probably wouldn't hurt your plants, but I don't know if it would have any positive benefit over other irrigation water.
