Humboldt Nutrients not Humboldt County's Own ( snow storm ultra, gravity, etc. ) is hype..... I dare to say moreso then Advanced!!!
They where one of the first lines I tried running when I got back into growing and all the new "medical grade" stuff was coming out. They had pretty bottles, nice nice artwork, and ok descriptions of what they where and used for. Sadly the line sucked for me.... smelled like goat ass rotting and the only advice tech support kept telling me was use more hydro honey it will mask the smell. As I went into more "cannabis gardening research" thinking there was something about growing bud that made it any different then all the other veggie gardens and such I have done over my years I learn something..... they are all plants... some have slightly different requirements generally based on region they originate from but they are all very similar in needs.
SO all this "cannabis/medical grade" stuff I started the see and learn is hype. As another poster stated above there are 15 different products the feed chart says to run!!! FIFTEEN!!!!!! They are making incomplete lines and overlapping lines in order for you need everything or you end up with defiecenies and holes in your nute regiment because they make it incomplete for profit reasons.
I run 5 items total well 8 if you count the changing of bottles for the CNS-17 when it comes to my "medical garden". 3 of these are only used at transplant and go directly in the soil.... 3 are the different stages of CNS-17 and I am also including my medium.
There are even simpler things like Dyna-Gro which would be 5 parts total including medium...... I use what works for me....
In my organics I am currently running a just add water mix. Don't get me wrong originally I had to buy like 10-12 boxes/bags to get all the stuff I needed/wanted for my mix but it was still cheaper then the 15 bottles of "voodoo juice" and lasts sooo much longer......
Humboldt Nutrients SOILS BROKEN DOWN:
"This product is a blend of 20-25% Canadian Sphagnum peat moss, processed softwood bark, coconut coir, perlite, earthworm castings, compost, dolomite lime, fish meal, soybean meal, bat guano, kelp meal and organic wetting agent (Yucca extract)."
Peat Moss: Stripped mined in tundra/sub-artic and forest bogs in Canada and such, horrid for the land takes 1000's of years to grow back. Saturation rate sucks generally required a surfactant to saturate even to an acceptable rate. See Yucca Extract*
Processed Softwood Bark: Pine, Alder, and etc.... BASICALLY THIS IS JUST FILLER!!! and worse yet its the second ingredient in the stuff.
COCO Coir: Good solid stuff, has a nice good air/water ratio and a good saturation rate nearly 20x its weight in water.
Perlite: Ok stuff, nice air/water ratio... poor sat. rate but does help with drainage and compaction issues which with peat and bark could become problems.
EWC: GREAT STUFF has many mircos, helps rhizo life, and etc. mild source of N as well.
Compost: well since they don't specific this could be anything..... some composts also have compactionclaying issues which can cause rooting problems, burns and poor homogenous medium mix. Which when combined with peat can cause drainage/wetting issues, "leak/drain" channels in the pots which prevent full saturation and nutrient distribution.
Dolomite lime: A PH buffer... this is nice and will help prevent variations/spikes in ph levels due to different stages in the feed chart and as mircobe life breaks stuff down
Fish meal: Source of N and some P and K can also help feed mircboes
Soybean meal: Source of N and some hormones as well as some amino acids as well due to protein content.
Bat guano:Unlisted but depending on type, diet, and region the bats are from can contain N, P, K, or a Ratio of any of the 3 and numerous micros as well.
Kelp meal: has hormones, helps microbe life, can help with flowering due to hormones contained.... Type of kelp again unlisted and also one of the last ingredients.
Organic wetting agent (Yucca extract): This is used as stated as a wetting agent, this is something which is used to break the surface tension of the water in order to help saturation of the medium. Due to excessive contents of Peat Moss and Softwood filler this is necessary to help them reach an acceptable level of water saturation in order to be used as potting mix.
Do not get me wrong I am not saying this stuff is awful or crap as its an ok premium potting mix and in IHMO no better then Miracle Grow Organic or Black Gold but for the price and the stuff its made out there is much better out there, and also much better can be made that do not require a large list of items in order to run a complete "feed chart". Also you can make your own mix, buy a different mix, or mix and match to your liking for alot less and alot more complete as well. It sure does come in a pretty bag though
