Most of them it is required that you grow your own product, Most of them do not enforce that rule . I have seen "organic" growers with broccoli as big as a football in the middle of August, I have my doubts that they grow it here in SE Texas when the temps are usually above 95 degrees in August. I grow leaf lettuce under shade cloth here in the greenhouse and it struggles until late September. Thanks the LB's are working like crazy!
