Yes it does. 18 small plants will not yield what 6 plants in the same space will. Instead of 18" or larger colas, you are 9" or less.I wandered a bit off topic. What I should of just asked is ...does vertical not matter? Im genuinely asking for myself because I was thinking of vegging longer
Math gets fuzzy when you start to calculate which grow style produces more in a year, because shorter veg = faster turns.
