Well, closer to 13 years. Scored this light: https://www.amazon.com/BESTVA-Reflector-Spectrum-Hydroponic-Elite-2000w/dp/B07923VR86 my opinion of LED's is low in terms of lumens but in terms of heat production is high. Phew, got that out of the way. I was a POW for ten years ending three years ago. Same question I had for the cops back then applies to me now. What took so long for me to get back to it? Back then it was what took so long for them to bust me. After all, at that time I had been growing for 39 years. I inherited these plants from a neighbor. He had them under a light and ran out of room. He now has two females under LED's. I put them in shade outside for a month after re-potting them in larger containers. Poor babies, got sunburned and consumed by grasshoppers. But now they are getting better, just like me! My first gro was back in '69 when I scattered a bunch of seeds on an uncle's farm. They never made but it gave me the experience. My first light and indoor gro was a MHHID in my basement with a single of sativa persuasion. Not knowing what I was doing it turned out bunk but it was a female and again gained experience. My next was with 29 pure strain Afgan seeds. OMG talk about tricomes. Huge leaves, measured 13" long fingers. This was a seed crop. I had seed for years and got a reputation for good product. When I was busted I lost everything. Now, I'm back like in The Shining. So, hey, look forward not backward.
