Sorry for the third post but this interests me, and I have some questions about your and others opinions.
I've been looking at mist cooling ever since I started reading about this topic, and they have these misting rings, that are meant for the big fans they have at sporting events, they're rated to 1500 PSI, and come in diameters of 12-42", now the reason I've been considering these is because when I'm thinking of doing the layout for the system, it'll either be trays in my mind like the aerojet/flo, or using a reservoir/flood rable with a top and then turning into basically an aerocloner on roids, or thirdly as one continuous spiral, as to avoid pressure drop at the corners, since there wouldn't be any corners. I'd imagine you'd have one plant site in the middle over the first nozzle and then spiral outwards, I know you could probably do the same spiral without the lines, for cheaper with more sprayers, but it's a nice piece of kit, so opinions gentlemen?
KM all you need is the all the macro, and micro nutrients, google a list, then check the labels of your products, make sure you have all of them, if you're missing micros, Kelp is an excellent way to incorporate the rarer ones, like gold, silver, etc that are believed to have beneficial effects on plant growth though understanding their function is beyond science.
Beyond that, all products are either A) designed to enhance growth rate of a healthy plant or B) help a distressed plant deal with disease/infection/infestation or aid them as a preventive before they develop.
I can recommend some compounds that help in the above ways without mention specific products.
For example silica aids your plant by making the cell walls stronger which helps when harvest comes and your fruit are breaking your wimpy branches, use during vegetation, stop during flowering.
There are brassinosteroids, from rapeseed which affect cell division and elongation, though I haven't experimented with them personally, in kelp however there is cytokinins which like brassinosteroids also affect cell division and elongation which is very important, as some growth hormones merely cause cell elongation, causing it to visually appear to be larger, while atomically it's the same size, where cell division causes an atomic growth of the entire structure, though eliciting both effects would lead to a huge plant.
Then there is salicylic acid, and chitosan, the acid coming from the willow tree, and chitosan coming from crab shells, both of these do not effect the plant directly, instead their is a reaction in the plants immune system that triggers it to vastly improve its defenses, this can be uses on plants under active stress to relieve, or it can be used on healthy plants to boost their vigor.
I hope that helps as a general outline, without all the marketing hype involved in the business.
