Most 'mainly' indica strains IME can finish under 2-3ft. .. Its all about how quick you flip them to 12/12. I too have height restrictions and have a few cheese strains on the go that will finish under 2ft. I clone them from a mother, plant them in a 2L hempy and switch to flower immediately.Thanks, I decided to try some Short Rider from Nirvana. I have had good results from their beans and I heard this will mature at two to three feet which is perfect for my space
