I'll keep it simple...

I grew 6 plants, White Russian under 1,000W HPS and 500W MH in a 6X6 area.

(You want a 2-1 HPS : MH ratio)

Veg 60 days, flowered 56.

I use the homemade brew without any ill effects and the result is incredible...

Does it increase yeild? I have no idea.

Does it increase potency? Absolutely. This is the idea behind the odd concoction.

Do not knock it til you try it : )

Is there a danger with mixing ammonia and palmolive soaps?

Only if you are a fucking retard.
