I wish I could train my plants but space is very limited in the greenhouse an as is I don't have much space to walk,one year I did start to train a tangie but once it started growing in to mom an dads section dad was more than mad an roped it back very aggressively with a lecture about taking another persons crop space ,although this year at 11ft an basically using the greenhouse roof as a scrog the blue kush gets a tie down right into the walk way now I got army crawl just to work on plants or to add top dressing and water ,i would love to have more vertical space ,bigger roof so i could grow skyscraper trees and start em early an veg ,an being able to train em as well and actually be able to say skys the limit but in reality in limited by a greenhouse roof and walls and plants are busting at the seems .
