Chill. Your selection criteria are not the same as everyone else's. For you and many others, $/lumen is the biggest factor. In that case, you are absolutely right, you can get a great LED setup with cheap components. We can all see the examples in the forum. For some people, lumen/watt is the...

Unless you're massively under-driving them, running the LEDs directly with resistors has large potential for thermal runaway, followed by burned-out LEDs. As the LED gets hot, the Vf goes down, and the current goes up. As the current goes up, it pumps out more heat, the Vf drops further, and the...

This is perfectly normal in plants grown from seed. I buried my early starters for my next grow deeper (took them out, crumbled the soil off the roots and re-planted). I'll probably leave the late starters to grow unhindered and see how both sets do. These seeds are for my second real indoor...

With all that purple, maybe a Purple Swamp Ass OG Delight?

The LEDs will produce enough light to grow some plants. Personally I don't use drivers that go above 45V because I want to minimize the electrocution hazard. Patrikantonius is right that they could be better in several ways, though I have to add that there is often good reason to include...

+1 for sativa-like, awake high with less tolerance. Even if it's less potent (down to about half), I'll take that stuff in preference to strong couchlock weed.
