Empire Builder soil

does anyone have firsthand experience with this soil? Its now available in my state. If any CA growers can give me the rundown on this stuff it would be much appreciated as I can get this for a very good price at my regular shop. Is it as hot as supersoil? Does it need to be used in the bottom third or so of the container? Any info would be great....

I'm also looking for more info on this soil.The dude at my local hydro store keeps raving about it and it's the same price as FFOF.

I am almost done with my first grow using Empire Builder. Had more issues than with FFOF. The girls went from one gallon pots filled with FFHF into three gallon pots filled with the Empire builder. So two gallons of the Empire under and around the FFHF. I dont think it was too hot but I did have a couple issues. Mainly seems like a lack of N. Starting yellowing pretty early (around week 4-5). I am only watering with a mild tea. Ive done this watering method the last few grows using FFOF and have had better results IMO. Its only my first grow with this so I will give it another try. Maybe do a side by side. Hope this helps a little.

They have another soil mix aswell
