There are some nice, small bushy plants that don't stretch alot during flowering like the Killa-watt, Sensi Star, and Hindu Kush that are very nice and manageable size wise.
If you want an indica, may I suggest Northern Lights Pure Indica.
Very small. Nice plant.
I would guess any pure indica plant would be short in stature.
I was wondering the same thing. Next year I am thinking about sneaking a couple plants in with my vegetable garden but they have to be small. I don't know much about the low rider strains, I guess it is time to do some research.
I love the idea of the Auto Flower. You can keep your lights the same all the time and stagger your grows using one grow area. I have to get me some of those seeds. Except I am scared to order.
