A pre-2k BB sativa grow sounds sweet, that is a fun plant to watch grow. I was just checking out Diatomic Humus, and that looks like some quality stuff! It looks like the "missing link" between nutes and roots. I can see how it would be easy to fry your plants using that stuff, as it seems like it super charges your nutes and frees up minerals and nutes from the soil and water. Soil seems to be a bit of a guessing game, what's in the mix?, how much is available? when?.... Most of my grows up till now have been in soil-less with hydro nute style feeding, and this is a much different, "cross you're fingers" til you figure out what's what kind of style. I can't wait, just when I get settled with the feeding, summer is gonna be here and fry me anyhow!
I really liked knowing exactly what my plants were getting using soil-less and chem ferts, but I have a feeling soil will payoff in the long run with ease and quality. But until then.............
