-Looking good bud!
I find a nice mix of Burple & white give me the prettiest buds & IR helps them finish on time.
Might be running a cheapies that are not very efficient but you will still get nice results.
250-350w of efficient, quality leds is enough to do a 2x4.
You're on 300w of cheapies? If so, id consider another white board.
400-500w of cheapies @ a 50/50 mix white & burple should do the trick. The white will improve your bud size & everything.
A few yrs ago good led was around 1.7-1.9 umol/j, now they are 2.0-2.8. Much more light per watt used.
Now cheap Alibaba burples have not upgraded at all, leaving you with less efficient leds then a 400w SE , HPS. Around 1.2-1.4. Pretty sad. 600w HPS is the most efficient SE bulb. Anything below that is even less.
If your QB thingy is 2.0 umol/j then that will bump your tent average to around the efficiency of OK leds a few yrs ago. Maybe 1.8 if you have x2 boards added to the mix.
This should land you around 1+GPW on average depending on your growing.
Peace!
