i grow amazing herb.. if i switched to mg id still grow amazing herb. i choose to use soil that i feel is better, but stressing the argument that you can grow decent herb with any soil is a wasted effort. the variant is personal growing ability. the nutes in the soil will be all used up way before the plant is anywhere near ripe (under most growing styles) so it really comes down to your understanding of how that plant grows, and the nutrient regiment you supply. good herb speaks for itself, and if you are enjoying the fruits of your labors who the fuck can talk shit about it?
im sucking down a vapor bag of some sensi star that was grown in a mix of roots organic and happy frog, i mix 2 bags of roots to one bag of happy frog. throw in some "plant success" for the benificial fungi, extra coco, and chunky perlite. amend the bottom of the containers i bloom in with extra worm castings and high P guano. and fed with a mix of organic and synthetic nutrients with added happy thoughts, good vibrations, Co2 and the laughter of elven children. I think there was some molasses in there too.. maybe some rocket fuel. i can't remember now.. sensi starship or something...
the gram per watt thing is called taking it to the next level. I think that's where the rocket fuel comes in
