looking for both .
Im guessing it will take some searching and reading to find the meter and use it, im not down with the mobile phone apps and attachments unfortunatley but i believe some must have posted Youtube vids which might explain it better...
Remember too without them being in your grow area the results are not as accurate.
I'm sure it grows. Pled has shady business practice. They are trying to rip off the Advance name. They also use a lot of marketing hype. Pled is no different than any other no name led panel.
Why not go cob? Plenty have tested cobs here and know how they perform. Others have tested them with meters here.
right I am currently looking into cob . the cost is killing me . 1 good cob is 22 or so a good power supply is 25 to 30 a fan and relector unit to hook this cob into 15 bucks . and it add up quickly almost cheaper buying one assembled . so a 600 watt cob unit will cost .370 bucks it will be a 600 watt true light . before I drop 2 or how I am drop 6 k on lights I want to buy 1 unit test it before I go all in . I have a cheap meizhi and its killing the veg seriously impressed I want to measure the par on that and my hps and order a cob set up just 1 unit so I know what the best solution for this money killer upgrade
I get that cobs cost. You are planning on buying a meter. Others have done the work and we know how cobs perform. Save the money and don't buy a meter and spend that on cobs.
