I have had my system running now for a couple months. 10x12 greenhouse with a couple hundred gallon fish tank. I have had mixed results. I have havested two cucumbers from three plans(might be using the wrong type of cucumbers), peppere aren't doing much of anything. Got a few sugar peas then the plants died, radishes didn't do anything, Tomatoes are very small, and the romain lettuce is bolting. The shallots did good, as did the garlic and basil. Could I be lacking in fish?
