Inverse square law does not completely apply when you have reflective walls. Instead you get wall losses. Which increase reasonably linearly with distance.

Also, a bare COB has a smaller beam angle than a HPS fixture like the Gavita Pro.

I pull the about the same from a 4x2x5 tent with 376 watts of under-driven cobs as I did 4x4 tent with 1000hps
Nice man, biggest factor of yield is growing area if properly lit, 4x2 is half the space as 4x4 so technically you should be able to double your yield in a 4x4 compared to a 4x2, maybe you are just better at growing now?

And maybe a 1000W HPS is too much heat in an enclosed 4x4 space, stunting plants.

Yesyesyes I know it can be vented but now we're playing the game of adapting to our equipment rather than our plants.

COB LED is just better.

Better is subjective to the user, if he couldn't handle the heat, then he should stay out of the kitchen, we cookin up a cake.

Derp.

No, we're growing plants. Doesn't it therefore make sense to use equipment that's best for the job?

Let's see how your cake rises over a campfire.

I use my ladies to pay the bills. When I completely switch over to leds then they wont have to stand under that street light for 12 or more hours a day with no time off. Well till they get fat and stinky, then they have to go. And in come the new more petite ladies.
