I wanted some opinions from people who have had experience with organic gardening to give me advice on items to purchase. During this summer I plan to go all organic outdoors by making my own soil mixes and aerated compost teas. So far I have a 35 watt air pump for making my teas, some ocean forest, happy frog, and earthworm castings. I was thinking I should get some alfalfa meal, bat guano, kelp meal, and maybe some bone/blood meal. But I really wanna get whatever is most important and useful for the money. Suggestions?
