What do you do when they stretch too close to the light? Can't raise the light because of the main plant.I would normally be inclined to Top and or FIM them, however I have a limited space at the moment with very small windows of light. So getting them high enough to poke up and compete with the big girl has been my priority. Currently I'm considering just letting them go and seeing what and how they behave.
On another note though, I'm considering what would happen if one had a large number of smaller cup/buckets and just let them veg for about a month and then stretch without any topping into flower. If one could get 3-6grams out of each and multiply that by the number of cups the yield might be interesting.
