Newbie girl light

the spam filter on the site prevents you from writing the dollar amounts. you can write numbers like 1234 but as soon as you place decimals in it or have it attached to a dollar sign $ it will edit out the numbers and replace it with a zero 0. I think you said in a previous question you go it for 400 something. I think you can get other lights that would outlast and outperform that optic 8+ for the same price point. Photon app is only good when calibrated, if its uncalibrated it is guessing and not accurate. it is repeatable but not accurate. Other light manufactures test their light in a fancy chamber/box and get you the PPFD maps the light outputs. if your lighting supplier can't provide the PPFD maps something weird is going on.

For that price it's a steal! Get the photon app on your phone. Measure the PPFD in the center and the corners and try to get a nice spread. Probably about an 18" hang height above your canopy will achieve this. For a 4x4' tent, you probably won't use more than 75% past the dimmer.
