I hope you enjoy the first indoor grow. I'm sure you will like the LED, I have 3 300w Mars LED's in my tent now and can't imagine doing it any differently. Although I would love to grow outside, indoors is the only viable option. Just keep in mind that utilizing LED's as your light source will result in increased need for CaMg supplements during the grow. I feed at 150% to 200% of recommended on CaMg and have never had a problem that I am aware of.
And yes you should save money as well. If I tally all expenditures this year, equipment, soils and ferts, seeds, etc.... I am somewhere just over a grand. My wife has had meds for her chemo issues all year, and we are stockpiling for a RSO run, and have not needed to purchase externally at all. Well worth the effort and minimal time spent and the quality control is completely in your hands.
