I haven't heard that one yet, but it sounds like it would work. I think I am gonna stick with the budxl though. I have run Botanicare Sweet before with h&g, but didn't really notice much of a difference. I might give the molasses trick though sometime. I know it does wonders with my outdoor.
I was actually talking about both. They make drop in coils that you can use to chill your reserviors with a room chiller unit. Something like this

I haven't heard of anyone getting 2 gpw from clone only sr71 PK before, but that doesn't mean it is isn't happening somewhere. lol There are however, several different "purple kush" strains floating around. I myself would be stoked to hit the 1 gpw with the pk.
I have been close, but haven't hit it yet.
