Yields are largely affected by wattage and plant structure. Veg time and plant numbers obviously affect
total yield as well which is really what you should be concerned with. Under your 600 with 6-9 plants, it shouldn't be difficult to yield 16-20 ounces. In-short, look at your light footprint and fill it with plants, if you know how to grow then the
total yields will come.
Actually, I never just 'pop into threads and drop pictures'. It's usually to back up a point because
talk is cheap. I look forward to the day when you stop talking and start posting pictures
