Phil,
I would like to take this opportunity to point out several flaws in your "system".
You took the time to critique my mix without first trying it so I will return the favor. I will also be doing my best to make your big head explode
1- It's a system.
2- Your website states "always ph your water". What? It is commonly known that one of the beautiful things about soil growing is that we don't have to worry about ph issues..in properly balanced soil. Your system takes away the ease of simply watering your soil straight from the tap. Now we have to buy containers, stage the water, ph it and then apply it. This is a big deal for those of us with large grows. The fact that you have to balance your water tells me your soil is not balanced.
3- Layering. From what I understand, per the pics on your website, the soil will be layered with the recommended promix on top and your blend on bottom at what looks to be a 60%\40% ratio of pro to kind. You show that the roots will sit on top of the kind blend and feed as needed. This creates a number of large problems during the veg cycle. (1) when your roots only utilize the top half of your pot then you have made unavailable to your plant half of the total moisture held in that pot. This is a HUGE deal in hot summer months. (2) when your roots are not grown into the bottom of the pot, the moisture in the bottom becomes stagnant and will promote an anaerobic environment in your pot..bad for roots, bad for micro organisms.
4- I see that you condone vegging up to 6mos in 10 gallon pots. We all know we will not see max plant potential with this practice. For customer sake you may want to present some larger soil quantity examples. Your site states that you will never see chemical burns. Well, this is true in the sense that it won't be "chemicals" burning your plants but from the pics you provided above we will see some burning.
5- Micro organisms need a natural well balanced rhizosphere. There will not be enough organic material in the promix for a micro organism to do what it does best and there will be an inhospitable environment for micros in your bottom layer. You have killed the very essence of what organic growing is about..the supercharging of soil by living organisms that break down organic matter into highly usable food for plants.
Sir I will put my simple mix against yours any day. You have exhibited ignorance about true organics in many ways. You have "organic" confused with "natural". Put that in your pipe and smoke it!
