What the title said. lol I run 24/0, the main reason I do this is that I do not have that area sealed from light. My questions is I heard 18/6 is better, prevents stretching when you go to flowering. Is it that big of a difference? What if I switch to 18/6 and I have some pretty good light leaks? Will I herm? Is it worth the risk? sealing it off from light is possible probably, but again, worth the effort? TIA * please note that I understand the need for darkness during flowering and I have a separate tent for flowering, this question is regarding only veg. ** also, this is not one of those life or death emergency help threads either, it is more of philosophical discussion.
