the ocilating component from a fan sounds promising....I think you could use a string and pulley system to move light side to side...probably wont move as far as a lightrail(6' of horizontal movement)but sounds promising...

Have you ever noticed the trich production is highest facing the light??? I've seen light movers give a higher yield and potency in others grows...if you are groing for headstash, a light mover is a great addition...I am gonna try the fan idea in my small area...I think I'll hook a n eyelet to each side and a string to my fan, then ocilate it and see how much movement I can get...

ceiling fan and duct tape



=p
i'm being semi serious here....

yeah if you rigged pulleys you could turn the 6 inches the fan turns into 6 feet technically. but make sure its safe, when I say a big glass dome, I was thinking of my 400 MH light hanging. its like 4 inch dome

so you guys are proposing what? i hang my light by the chain as normal and hook a fan to it so it swings back and forth? thats all everyone can come up with?????

I guarantee you could make one for less then 300 if you go to home depot and search

A rotisserie cooker motor is all I can think of. But no sure how to make it stop and go the other way.

yeah if i could make a big circle disc i could hang lights on that and put a christmas tree spinner thingy upside down attached to the circle and lights would be more productive.
but i didnt wanna use that type of setup thingy.

how about a small quite garage door opener just a thought

just go by one. You know it will work and you have no worries. It like $200 and you will see results and get what you put into it 10x.

Good luck

no go brother. those are all chain driven as far as i know of.
