Maybe I'm dumb....there are times that I am indeed not-that-smart, and this may be one of those times.....
I don't get the entire brain exercise of grams per watt to indicate how good a grow is. I have 1,650 watts in a 5x7 room with eight plants. All I know is that if I get 3-4 ounces per plant I'm doing fine in my world. The entire gram per watt thing really depends on strain.
I do admire those that attempt to grow a "perfect" plant. It's those of you that are pushing the envelope that advances are made. I've tried the numerous hydro-store nutrients and found it was just more things to get wrong than to get right. I'm by far no expert on growing, or pretend to be.....but I like keeping it simple. Take a look at my journals and you'll see I'm not doing all that bad for a beginner. My early lower yields were with expensive nutrients, my bigger yields were with non pot-specific nutrients.
Just saying....
I'm done hijacking your thread. Good growing my friends!
