You're all over the place, dude.
This is what you said - "Burple grows slowly, and does small plants. I bought a burple and learned this the hard way."
You were speaking in general terms. Not a 300 watt blurp vs a 1000 - that's just ridiculous. Of course the 1000 is going to smoke a 300 watt panel. That's obvious. A 1000 watt HID is going to crush 300 watts of anything.
Again, in my experience running blurples, they didn't cause my plants to grow slowly and they got just as big as they did under a 600 Hortilux. Penetration wasn't an issue. You're making blanket statements that aren't exactly true.
