Naw but I use a lux meter on my phone. It's not accurate to the real world but I do know what it takes on my app to get good growth cause I've used it so much. Anything over 10k will work, 20 to 30 seems to be all that's needed. Over 40k seems to not be any difference above that. I'm hitting 26k at the the top of those plants. Outdoors aimed straight at the sun gets 80kDo you know the PPFD at the tops of your plants?
