I was more worried about extra dust and stuff getting caught up in my fan. I do technically need to hide it, but yeah Im not really worried about that until flowering begins, plus im running photoperiod my first couple grows unless I have some auto freebies. I might throw one in while my photo plants veg but I dont wanna get in over my head. Once i either get it, i dont have to worry, if i dont and I get my refund Im gonna buy straight from the manufacturer. Im kinda getting sick of amazon, they keep screwing my shipments upYou won't need until really until you're into flowering. I don't even connect mine until they begin to stink. I guess that depends on how much you gotta hide it, but either way you're good for a couple weeks
