ive started growing tomatoes at home with a mixture of soil and compost… is that organic?
This is not the best, but it is a GOOD laymen definition of OG:
"ORGANIC GARDENING – the science and art of gardening by incorporating the entire landscape design and environment to improve and maximize the garden soil's health, structure, texture, as well as maximize the production and health of developing plants without using synthethic commercial fertilizers, pesticides, or fungicides."
