PenguHBanswered grow question 3 years ago If it's 80cm working space then yes, you can. Remember your lamp will need a safe distance from your plant. There are some tiny strains that would fit in there even without LST, such as Quick One or Royal Dwarf. Alternatively you should be able to train your plant to grow sideways a lot. You can also consider growing a standard feminised plant instead of an auto, so that you can decide when it stops growing by lighting schedule.
All the best!
