Ok so first your going to need some mylar ,cardbord ,tape, string. Shape the cardboad into a cemi circle then tape around it so its more stable and it will stay in place. Next just wrap it with mylar and tape. Make 2 holes at both ends -i would recommend using a pen for this . Push each piece of string into the holes and tie at the end so it doesnt fall out. There you go you have your own reflecter and can adjust the hight of it by moving the string. Hope this helps all the Growers. By the way GRASSCITY FOR THE WIN!
Im sure it helps. But why not swap the tin foil for mylar. You should only need a metre or less so it will be cheap. I hate tin foil!!!!
Mylar is the better choice. And, you missed a spot where it still says tinfoil. If you are going to do a tutorial, you should include some pics. Makes it easier to follow the steps. Peace.
i made a massive sized "air cooled" trapezoidal/pyramid shaped one for a ton of cfls i was using(didnt have good ventilation for the cab) used flat white computer paper and a piece of plexi glass to contain the heat. worked pretty damn good too since cfls didnt get hot enough to mess up the plexi and i could pretty much let the plants grow into the plexi and bush out. gave all the plants nice even growth and light dispersion
