hey guys iv got a question about light and distance. in the cab that im building there will be 16" of room between the top of the res and the light. im thinking of makeing the light adjustable vertically. would i gain anything by this out of the 150w hps or should i just mount it solid?
You should fix the light and you can just boost up your res when they are shorter. Probably only need to change it a time or two during the stretch.
In my case, I gained at LEAST 2 inches by mounting it to the top of the fridge. For me, that alone was worth it. You will have to prop your plants up a bit when theyre young, but under a 150HPS you dont need them that close anyways till they get bigger.
I say mount it to the top all the way. Is it 16" to the bulb itself? And is that with it mounted to the top or hanging? Remember, anything closer than 4" to that HPS risks getting burnt. My top buds all got fried and they were considerably more harsh even after a 2 week cure.
Good luck whatever you decide!!

disfunktional, no reflector? That's one of the easiest adjustable light setups. You probably have an idea what you want but here's a suggestion. A simple grommet or (cord) strain relief can be sized tight enough to easily hold the weight of the bulb and socket by the cord. Simply pull your lamp cord to either side of the grommet to raise or lower the lamp.
I'm with catman and KolorBlind about it not being necessary. It would be cool, though.
