Hey Rose, I brew 5 gal now with a 6in round airstone from a hydrofarm airpump. I bubble the water for 24hrs to remove any chlorine first. Next I blend in worm castings, guano high in Nitro and phosp in a mesh bag that I soak later. I add maxi crop liquid kelp to the water with earth juice grow or bloom depending on were I am in the grow. Lastly I add a 2-3 tablespoons of molasses to the water. The earth juice I use the proper dosage per gallon of water. I brew it for 48 hrs, if it smells bad toss it. I use it full strength on my plants, pH adjusted with my digital pen to 6.0 6.5. I will alternate between this and just fresh water. I always get better medication when I use a tea. Feed the soil.
