How much do you dilute the Nitric Acid ?

I dont dilute HNO3 I just buy it. And put in rez...with small amount 7.8ml to 100L
Yes I use organic soil with "pure water only" for the first 30 to 40 days. Then put the organic core with a plant in the soil-less mix and feed water to the outer edge of the container leaving the inner core dry. When I transplant the plants into soil-less, I switch to low ppm nutrient feed with every watering.
.
When I add different types of finely screened clay to the organic core, I have a higher cation nutrient exchange.
I'm still working out the details on the differences with EC between the different aggregates. Cation exchange capacity is usually measured in soil testing labs. Since I don't have the testing resources, I have to use the plants' growth as a gauge for testing. It's slow work but fast growth. Here are a couple of photos of plants I'm working with now. I start the seeds in the organic core and keep them there until I can sex them and that part is slow. Only pure water at the first stage. Then I up-pot the core into a soil-less mix big enough to flower in. The larger plants are only 7 days after transplant. The plants are 37 days old from sprout today and ready to flip to 12/12! That's when shit really hits the fan exploziv when I start feeding the plants and going into flowering.. Just one 200 ppm feeding at this point.

Looks great, man! Ang I mean really nice system you got there! Only thing i see that might be wrong is that floor space is not well utilised. You could fit more plants that size in there. Am I wrong?
Anyway, if you ever start a thread tag me in there, or pm me a link. Thank you!

Your welcome. Its a six by five ft area. The first photo is missing the males when I took the photo, I had 22 plants total. This room will be full in 7 to 14 days. I will have to remove more plants due to space limitations soon. ! I've almost got all the kinks out and will do a thread in the near future. I may post a few upcoming photos here just to get an idea of what I'm talking about. Thank you for your interest.

call me old-fashioned,..... but i still swear by good ol general hydroponics .............always worked beautifully for me
I'm old-fashioned and love GH too, but still like to learn new methods for growing. I'm amazed at what people can do in the indoor horticulture world today. Not to mention the greenhouse growers' techniques, light deprivation, acid injection systems, controlled photoperiods. There are so many substrate systems today, it's just unbelievable. However, it all comes down to 18 essential elements and their delivery system.

Ok here's is a 12-day spread before and after... Using an organic core in the center and feeding the outer soil-less can boost the Cation Exchange up to 200%. This is a nutrient-feed method using Hydroponic fertilizer. I'm using a 3 part GH flora series and feeding only 169 ppm or 0.3 EC with every watering. If anyone has any questions, I would be glad to answer them if I can.

Its good to put minimum nutirents in soil while giving them every watering some food. give some pure RO once a week for flushing a bit...they look healthy.
You make a good point CANNA and most people would do that to avoid excess salt build-up. Here's the key to using this method, I keep the cation intake available with every watering at a low ppm. The organic root mass core has a negative charge and acts as a magnet, so it's important at this point to have fresh new cations there with every watering. The plants are going into flowering and the low dose ppms will make the nutrient transition much easier too. I allow run-off with every watering for fresh nutrients and oxygen in the roots and get an EC and pH reading. Thanks for the importaint tip CANNA
