In Hawaii you sure can.
Plant in late January. The short days trigger bud development. But the days are getting longer. The top will bud, the bottom branches don't. This only works on full Sativas. The plant shown is a Bloodweed mom crossed with a Black Thai dad.
In late April you take the tops and larger buds. Leave the bottom 4 branches. This gives you a sample of the smoke, and an idea of what it looks like. Then you let the long summer days do their thing
Here's a series of pics following one plant through the entire process. Started in Jan, taken mid October. Yielded over 5 lbs.
