pop22- Thanks very much for the reply. First time using the Lux app on a Samsung phone. I was mainly using it to compare the QB to the 150w cmh I had in the cab. I have three new 150w cmh bulbs - all three measured 32K lux at 10" from bulb. I slid the new QB into the cab and get the 52K at 10".
I know the app could not replace a LUX meter but just using it for comparison it appears I putting much more light to the plants. Both with app and my eyes. Here's the deal- I used the QB briefly a couple months ago and just ruined a batch within days at 120w. I may have been a little to close but I am one gun-shy kinda guy right now. How close can you get your tops to a board ? I have 18-19" soil to QB
