ok i am not gonna wig out on you like sparky did.....however i have read and re-read all of his threads and yes, on post# 21 al says, well....you just quoted him so you know what he said. but let me say this, and it's important for us all.
anyone who does this well will acknowledge the tremendous learning curve. al will be the first to tell you that he is not exempt from this. his mine and your grows WILL change and the beauty of that mans threads is that they chronicle all the ups and downs of his op. such as ppm and medium. if you dont read it all (and i understand why, fuck its huge )]then you will miss these pivotal plot points in the show, lol.
the short answer is that he changed it. he changes lots of things. he still learns new ways to improve yields and cut costs and he passes all that along to us in his painfully long threads. some will argue with his methods and fail miserably and some will do just fine. i am a skewl of fuct student as is everyone here ....even sparkys mean ass. i promise i wont try to steer you in any direction but the right one. i am pretty excited about your grow and look forward to seeing it do its thang
and i'm not castagating you in front of the class 'cause thats not how i do it. i think it's good that you just quoted my friend and hero , that means your willing to read....sparky would be proud.
