I love them but have not been able to grow them outside due to cabbage worms. Where do these worms come from? How do they find every cabbage crop I have ever planted outside? I won't use pesticides but I will use indoor hydroponics. Growing indoors using hydroponics has a number of benefits including no pests, no watering, no worry about frosts. The unknowns are spacing, varied nutrients through its going cycle, and providing the right structure to support the plants. I'm in the planning stages now and hope to have a crop growing by mid February.
