the 192x3 is great for both. When you hit the switch bloom on you will see the red kick in big time. The give you full spectrum in veg and added red in bloom. You can check out my videos i did on the 144x3
that light will cover 4'x4' no problem. I would say 4 or 6 good size plants. When you ask how many plants it is hard to say. I see a lot of people on here that flower really young plants. So lets say 4-6 5gallon pots or buckets with very nice yield.
My 144x3 has to big plants and six medum size under one light doing great. And the bleed over is growing 9 cucumbers and twelve tomato plants.you can see that pic as well I just posted some more
