Homemade Light Mover

**WidowShamus** · 03-18-2010, 06:16 PM

Guys, I have always "daydreamed" on how I can make my grow space more efficient (meaning grow bigger buds). I hace a 3 x 4 x 8 foot growing area and am using a 400 watt mh then hps bulb. Since the ceiling is 8 ft high I have the 35 pound light hanging by two chains which I can raise and lower as needed. I actually went to a hobby shop a bought small 30 rpm electric motor which I attached to a round piece of wood. Similar to a train wheel and attached a rod to the outside area of the circle and the chains on the other end of the rod. When I turn it on it swings the light like a clock pendulum and does the exact same thing as a light mover. When the plant grows all bud sites are large as compared to the usual top bud being larger. In a scrog grow if you bend the fencing slightly to match the angle of your "swing" you wont be dissapointed. Shamus

So, what are you saying? Your light is a pendulum that swings every two seconds? Kool! How about some pictures? How long have you been using it? Had any results yet? How big of an arc does the light actually make?

It seems that the "Moving Light" would creat it's own air movement and, along with, the thermal raise of the air, you should have excellent, passive, ventilation - given adequate ports.

I've been looking for any, and all, info on "Cycles Per Minute", as it applies to "DIY Light Mover Projects". So I find this quite interesting!

Pics!!!!!!!!!!!!

Ill get some pics up soon. As for the size of the arc it depends on how big the circle of wood or whatever you use is. My room is 4 foot wide so I'd say every second 1/2 it passes by. Yes I have used it with good results compared to grows when I didn't.

maybe a reinforced ceiling fan with the lamp attached, get a digi timer with 100s of settings, have the fan go on 1 minute every 30 mins or so x D

cept the cord will bind up... this is good weed

Ok, my camera is mia for now so I drew a crude picture of what I have going on in there. Its not complicated and pretty self explanitory. Hope this helps all that are interested and maybe who knows someone will sell professional kits some day at your local garden center and it all started here, lol Shamus

i like it. simple. i bet it would work even better with rods and hinges than a chain

reminds me of a drive wheel from a steam locomotive...
u mentioned hobbystore, does someone have an interest in model trains?
lol i used to... its an expensive hobby tho

You know the more I think about it the more im thinking that why is it the light that has to move? I can easily move or "spin" the plants themselves. Something like a turntable. Same low RPM motor. I havent built it yet but its a pretty simple design and very effective.

i feel safer with this idea over a swinging light

sooner or later that light will work itself out of the ceiling
its to heavy to be swinging back and forth like that
hope your home when it falls
