@ vertivalgrow thank you for that info. I actually have a quantum sensor coming in so I can precisely dial in the ppfd. The info given on these lights is sketchy so I will test my light and post the results for anyone interested.
hey airwalker i have question about this quantum led 480w i have it around 36" from the tops of the seedlings at full brightness and temps are high is it better to lower the light and lower the brightness? You seem to be the expert on lights haha. Thanks in advance.
