Is it worth it to build some light reflectors above lights.

Ok, it's not all that pressing at the moment. But I am thinking about building some simple light reflectors out of some mylar lined cardboard to wrap around my lights. I will also be adding 4 more lights, so I'll do this for all of them.

The plan is to build one reflector for each pair of lights, so I'll be making 5 of these in total. Is this worth doing?

Here is a picture of what the plans are.

At lowes they sell a light meter for about 11 bucks that has a ph meter also for water and dirt
this may answer you question and might help you with all your grows
I am thinking about getting it to be honest

Do you have a link? As the ones I saw are those green ones that everyone complains about.

Bad idea bro, that light,water, pH meter from home depot is crap. TRust me don't waste your money on that thing.

Yes, a reflector can improve lumens by as much as 40%. I use cfls and use a reflector made from mylar. This isnt the best pic but will give you an idea.

Cool. I will definetely be creating a reflector of some sort now!
