Not positive but I've been told and also read that if they are kept under MH ( blue spectrum) till the stop stretching and it's kept close( but not so close it burns them) that this will cause them to grow short with shorter internodal length..and also if the are switched to flower nutes and HPS early that this is another way to help control height..lastly pot size is a factor ,smaller pot=smaller plant,,but there are variables and sometimes the plant just does what it wants to anyway..my DP plants are in 2 gallon bags and they are still 42"/108 cm also I fimmed one plant 14 times to try and slow the vertical growth,or it would be like 6 feet tall....peace
That's what's it's all about @scott04_40 .without trying and finding what works for your situation,it's all here say !! There is another thread in the coco section that encourages defoliation training throughout the grow as opposed to one major defoliation,which again goes against conventional thought!! My next round of plants will all be the same breed so I can get and run a controlled experiment with different methods,and all will be documented ....just my thinking based on what I've researched: if a plant is " predetermined" to produce a certain amount and grow to certain size,training can be done to alter the shape,and if if can be done without shocking/stunting the plant it will still produce that said amount,just on a plant that has a different structure...my thoughts tho ,and when comparing my two pants ,the fimmed plant has the bigger colas,but the natural plant may out produce it in the end..peace
