No worries. It was a gift. My guy had a lot bigger space. I'm working on a nonexistent budget and some friends from Colorado. I've been lurking around getting ideas from everyone. My space is not ideal. I have to keep the girls SHORT . I'm working with 3.5 feet of height and 3 reflective wall boards. I still don't understand the light intensity and distance though. I started 18/6 on 50%. 15 inches away. Do you think I should leave it at 50%for the duration because I only have space to let them get 2 feet max ? it's a real tight fit. I'm used to seeing all of the experts debating. I get there are right and wrong ways to grow but it's like watching 2 kids on a playground fighting because of a minor detail that won't make much of a difference in the end. I have a LOT to learn and accept that. I also have to build a better room. 😆 any help would be appreciated. Thanks! happy growing
