I dont think its always easier. Is it easier to figure out the watering schedule of a plant in the ground? I think so. Is it easier to conceal plants outdoors? Not compared to a room in your house, and still get good light. If you have a primo spot then thats a good start. The variables outdoor are different then the ones indoors. I've got spider mites indoors, but not outdoors. I've got deer outdoors, but not indoors. I would say I enjoy growing outdoors more. There is just something cool about growing from the earth, and using the best bulb money can buy (the sun). I tend to put more work into my spot then I do the science of perfecting a grow, and by more work I mean anything that allows me to do less work in the long run. My outdoor has a few ponds with fish that I pull water from, an auto timer for the long weekends, sun allllll day (I love California), and neighbors are no where to be seen (I really love my piece of California). Once I put up the fence around my grow, and got rid of the huge pack rats nests that were flanking my garden, my outdoor became the easiest grow possible (for me personally). Get the design phase busted out during the off season, and get the manual labor done as soon as the weather permits.
