I make my own light meter with a photo resistor and an ohms meter. I have calibrated it with new light bulbs so I can understand what it's telling me. The meter has to be the same distance from the source to get anything that means anything.was there foil infused stuff back then.? and the metrs suk. they arent accurate at all was more my point. ive tried a few and each one had diff reading
Home made is only cheaper. You still have to figure the readings. The main thing is that you take your reading from the same distance from the source. I use this so I know when to change my lights.ya and each meter will read diff...homemade is more accurate???
I would never use tinfoil. I at one time bought acid at that trailer park....you will get hot spots from using foil....I'm not going to go through the whole google process, but, you'll find many foil burnt foilage images here on this very site. All in all, your reflective materials used will show at harvest time. You'll not see big yield'n growers using the shitty foil...sounds like the trailer park boys are on here give'n advice again, ehhh?
Despite the fact that this may be a fire hazzard, I'd rather hang white bed sheets before I used tinfoil. It's the types of wavelenghs that are being reflected that is important, not so much the intensity.hey guys, im not trying to thread jack or anything but i was reading through this thread because i was thinking of putting foil up myself and i noticed some of you guys seem to "not" like george whatever his name is, anyways i was actually getting ready to buy a book that was written by him and i was wondering if there was another book you guys think would be better(recommend).from the way you guys talk about him it sounds like his theories are outdated? i dont wanna buy a book with outdated theories.....thanks and sorry to interupt
I like Ed Rosenthal's and Greg Green's books, Jorge is kinda hokey and a little outdated but there's good info there also.wondering if there was another book you guys think would be better(recommend).
