GMSgrowsanswered grow question 3 years ago We all long for tight spaces nodes, but then again you don't want them on top of each other either. Just makes for longer buds that are easier to trim then a bunch of little nuggies all over her. If your using good led or hid while in veg, there's no worries about the nodes being to tightly spaced. That happens more with fluorescent lighting that is kept very close to the tops of plants.
