Lol don't grow 100 plants grow 98. The laws change at 10,100, and 1000. Next grow try a scrog and buy a digital ph meter and a ppm meter off ebay the should be under $10 together and it'll save you a headache in the long run. And buy a calender and a note pad and record when you fed it, what u fed it, when a problem occured, and what it was. buy multiple seeds of the same strain pick a pheno that you like and make it a mother plant. Different strains have different needs and face different problems. If you grow the same thing over and over again you can anticipate the bullshit and spend less time fixing problems and more time perfecting the art.
