WOW ok, I am amazed how this thread has went for over the year its been running.
I use HN, ORGANIC only, only the 2 part, and basically its a supplement feeding at best. I have my Foliar spary stuff ( basically C02 and light seedweed/kelp extract or just plain water depending on the time/stage) then I have my in ground/ plant to waste feeding, although soil stores stuff so not exactly waste.
As far as I am concerned this line is meant for larger pot soil growers such as myself and my OD friends. It askes to be brewed, not 100% nesacary but it helps the micros and stuff multiply which helps uptake and storage for later parts of the season.
If you read the NPK numbers it is super low compared to most products and specially compared to some of advances line and other "hydro specific/prefered lines" Throwing some of Advance stuff for me into my soil will do 1 of 2 things; burn the plant or run straight to waste and be useless.
Anyway..... I am a huge fan of the 2 part Organic, used in conjuction with the rest of my feeding program. Its a good solid organic light nutrient giver btw I run about 1/2-3/4 what the bottle size strengthwise feed each pot lightly then supplement for additional mositure need mt. spring water. RO water is ok, but is missing trace elements hence why need 10-15 different $50+ bottles to do with what these 2 bottles, some good well or even tap water, and some organic fish emulsion and nice soil mix can for you!!!
As Dr. Frankenstine said " ITS ALIVE!!!! " which is the same reason to all my soil mixes I add 1-2 small shovel fulls of my outside yard dirt, " it has the mycozzaie, worm eggs, and other bacteria that is needed in symboisos with the roots and plant needs to help use whats given and provide in one way or another what is not, where in hydro everything is so rushed, "weak", and "sterile" what is not provided is missing period!!! So if you are not providing its all and in the right order, amount etc. it will work on not!!!
In soil you have the power of life, in the Humboldt Nutrients Organic line the power of life and the dependence on life is there.
IT is a rocking line with used properly, I for one would never run a hydro grow with this stuff I do not find it the proper tool for the job, but as my above rant/lecture/informaction session shows for larger pot organic feedings as a solid supplementery factor for good soil / organic regiment its PERFECT.

Just my 2 cents........
