yeahjosh thats right you hook a small light up to a timer or light sensor then let it shine on a couple of branches and those branches will hermie.. be carefull outside youmay get more than you are lookin for, but i will say outside plants are a bit more resilliant to light changes and small amounts of light... the light you use should be a small one like a few lcds or a 15 or twenty watt..and if you want to be extra carefull isolate the branches in large clear plastic bags, just be sure to ventilate the bags by opening them every day.
