as much wood as a woodchuck would chuck if i a woodchuck could chuck wood.
How big of an area are you filling...
work backward from that area... figure 4-6" by 4-6" per cola. so 10-17cm? x 10-17cm? per resulting vertical cola. That light is probably good for 3sq ft of area for photoperiods (12hour schedule), give or take and 4.5sq ft for 18/6 autoflower schedule. You can push that a bit, but if you go too much larger it will noticeably impact quality of buds...
Looks like your light will be the bottleneck. If you do 1g/watt with cob LEd, that's fairly decent. you can probably push to 1.5g/watt with that light at best. So, I'd expect 100-150g, becaue "optimal" is really hard to reach. (assumes ambient co2, add 20-25% for consistent 1300ppm co2 and a dialed in temp/RH environment)
That is only in reference to its efficacy... the light is perfectly fine and will grow good buds. you'll just spend a few more watts relative to a more efficient LED light with newer technology. In the context of 128w scale, this is "pennies" difference in watts, so no big deal, but if you increase scale, consider efficacy more.
