I quite agree, there is no magical soil. However, many of the best grows seem to have "magical" results when there soils are pretty high in Calcium.
Just visited a grower this week here in Cali that tried his recipes in various parts of the US and had terrible results. Same nutrients, same lights, grow design, etc... everything. What was really different? The worm castings and organic materials have a much different chemical profile in Cali than in other parts of the states. I will have a whole lot of those soil analysis comparisons between several states in the next 30 days.
Water quality also varies greatly as well. All of these are dynamics that must be understood and calculated for. Lots of you Cali growers are just in the right place with the right water. Makes it a lot easier that is for sure!
There is no magic. There is science. And so far, the science is consistently showing us the same over and over. High Ca, in the proportions with other bases that need to be maintained, the more amazing the grow.
We have a pretty big data base formed from a number of growers from this last season. The numbers don't lie nor do the yields nor the quality.
Indeed. Simple combination of mountain air, mountain water, ice-age minerals in the soil (plus a soil analysis to ensure the correct balance)
and a state that is super anal about organic quality amendments/products.
