Yes I am new grower, I've been around my friends grows allot and helped out. But this will be my first start to finish by myself.Im doing very well with an AKxCritical Mass strain, known to be heavy, and the biggest problem one will run into is light penetration even with 3000w IF you're serious about a 6 foot WIDE plant. Do you realize how wide that plant is? Even a 1000w (which I run mostly and all vert) will have trouble penetrating deeply enough to get any light to interior buds. Nevermind covering a 6 foot TALL plant with a 1000w vert presents its own limitations. That's like running a 1000w over a 6 foot tall plant and expecting the bottom half of the plant to yield anything more than tiny popcorn. I don't know of Ghettogrow's exploits but I'd probably question his dry yield totals too.
Not calling him out but after this many years of non-stop growing, Ive realized a lot of the legends of past yields are exaggerated.
Can't compare outdoor grows to indoor so that's irrelevent. So many reasons why. Do you grow? No offense but "newbie" in your handle doesn't inspire confidence. You're pointing to other people's claimed yields. How are your own? I'm speaking from experience here, not hearsay. Yes I run a system very similar to Heath's. 27gal tubs with bottom feeds and top drains recirculating, indica trees, vert bulbs (3x1000,2x600) on a flip between rooms. CO2ed, measured humidity, constantly monitored hydro solution of House and Garden Aqua Flakes and supplements, 1/2hp chiller, 270gallon total volume, pond air pump, etc etc. Yes I run a similar system to Heath's. I don't claim to be a master grower but I hold my own and Ive pulled up to a pound and a half from a tree in a perfect circumstances dialed-in system. That's a pretty damn big plant indoors. 4 pounds? 3 pounds? I seriously doubt those numbers as completely dry product. Just my .02.
Not trying to say negative things about you, but if your gunna come in here and say Heath is bullshitting then I'm gunna go ahead and tell you, if you've been growing for years and can only pull 1.5 pounds from a tree using hydro, you are WAY off the mark, seriously!!
My friend grows Jack Herer, puts two plants under one 1000W light and reflector hanging above, not even vertical style!!! Running in soil in just plain Pro Mix media, with GH 3 Part Nutrients and he gets 2.5 - 3 pounds a light. I could only imagine what he'd be getting if he was doing this in hydro plus if he had lights hanging on three sides of the plant. Believe me when I tell, big difference from somebody that has grown for years and someone that is a MASTER GROWER!!! I'm definitely not saying I'm a master grower, my buddy wouldn't even call himself that.
