Maybe, but I think it is because he is able to provide optimal condtions with his aero being dialed in, nutes and everything. When you finally get it right, it seems all the trouble and expense of going all the way with HPA could be made up for in the extra yeilds of your first good grow. I don't know anyone else who currently has as nice of roots, or as good of performance per watt. It's a good inspiration to know that these results are possible for us if we keep working towards it. Alot of growers consider 1gram/watt the target to shoot for if you have everything perfect, while tree farmer would be scratching his head wondering what went wrong with these numbers!
My chamber is nearly done being retrofitted with the foam application. It really looks ugly as crap inside, the outside hasnt been compromised except for a few ripples due to overexpansion luckily. Hope I will fill the inside with so many roots that it will camoflauge the ugly foam so I can take some nice pics
. I have a feeling however, that this thing is going to perform like a giant 5 day igloo ice chest, and that's what I was hoping for. Atomizer once told me a possibility for a root chamber would be one of those freezers with the door on the top. It's well insulated and you could retrofit the thermostat with a different refrigerator model that would control it in the 60 degee tamp range. Not really worth buying a new one for the job, but if you have an older one sitting around, or can find one on craigslist for 50 bucks, wouldn't be a bad idea to try.
