2000-3000+ lumens/square foot. The sun is 10,000/square foot, so ofc you can go higher than 3000 if you can deal with the heat. Less than 1000 won't give you very good results at all.

The generally accepted rule is 10k lumens per sq ft during flower.

That is exactly right.

A mixed spectrum is the best with the balance leaning towards one or the other for the different stages. If you are going to have multiple lights mix them up
I've always done just one or the other, does it make a whole lot of difference? If it does, then I will be changing...

Not a whole lot, but a small difference. If I had 4 bulbs I would do 3 of the same and 1 different, with only 2 I would stick to one spectrum

lol so what exactly u mean by a mixed spectrum. whats a good combo lol? one 6500 and one 2700
He means having both 2700 and 6500 mixed. But this was his advice: "If I had 4 bulbs I would do 3 of the same and 1 different, with only 2 I would stick to one spectrum"

I use a 600 hps, and a 400 dual spectrum MH gives me something like 1/4. But I'm planning to add 4x 125w purple ecolight cfl's, which will give me about 1050w red and 450w blue.

Purple, really? I thought the colored ones were just for fun, not growing?
