Indoor and outdoor growing are different so I think mastering them both is what we should be going for if your into it. I think the risks of both are why Farmers say don't put all your eggs in one basket. I enjoy growing indoors in the winter and I think the lights and greenery help fight off depression however battling heat and humidity indoors in the summer can be stressful and nobody grows weed to great stress. Its also really cool to come home and be greeted some 7-8 ft tall plants, just dont forget to kiss the wife first, not the plants. I will continue to do both but I will specifically look for seeds that are mold resistant next year.
