So sm-90 was recommended to me for control of fungus gnats, root stimulation, and more.
I picked up a bottle (legal again in Cali) and noticed it says nothing of the uses I have heard about.
It is being sold as a wetting agent according to the label.
1% coriander oil
94% sulphonated canola oil solution
What is the deal?
Does it really get rid of fungus gnats? (if it does, how much to use if I hand water coco?)
Does it screw with enzyme products? (I saw an inconclusive thread about using it with cannazym).
Does it enhance roots?
OK so I called the company that makes it and they said the label is vague because of the red tape involved by mentioning pesticide use in California.
They are going to call me back tomorrow regarding if it OK to use with cannazym/hygrozyme.
The person I talked to said they were 99% sure it wouldn't kill any beneficial bacteria or enzymes.
We will see...
Get back to us on that one. I haven't had use for it but, had decided it would be better for me than Hydrogaurd as I don't do the bacterial thing. I thought the point of SM-90 was, it killed everything except the plant itself.
scope the 'ethanol'
i took biology, not chemistry, but three ethanols in an amine group sounds deadly
at least as far as any practical bacteria or myco
enzymes are a different story, methinks
2-3 ml/gallon as a drench with or without nutrient
5 to 1 H2O/SM-90 ratio for a spray
i'd run the enzymes without it, just to be on the safe side.....

theres not concern for it being hazardous expecially at 5% by volume. google MSDS Triethanolamine, that will fetch the Materials Saftey Data Sheet for this compound and its pretty benign, though all bets are off it you decided to drink it.
as far as its function id say that it probably has to do with Ph stabilization of some kind judging from the 3 exposed OH groups on the ethanol groups, which will freely donate a hydrogen atom. im willing to bet that it was added because one or more of the other ingredanse is more basic and the TEA(triethanolamine) is used to counter act bringing the Ph back ot neutral. why not use some other chemical to stabilize the Ph other then TEA? well because its an amine that means that there is a nitrogen present and in this case the Nitrogen is located directly in the center with the three ethanol groups shooting out from it. nitrogen is very happy with three single bonds and wants to remaine that way. so in commercial application that means that the compound, wont degrade creating unwanted by products and possiable unwanted interactions (ie killing your plant) and #2 its stable and inert. it wont interact because all the atoms present are happy and want to remaine that way.
Im good with math
I got a "D" in chemistry in college. My idiot advisor suggested I take it again the next semester so that my second grade would replace the first for my gpa calculation. I got an "F" the second time around. Needless to say, my chemistry book had the misfortune of replacing a target for expansion testing .223 hollow points. I am now a lawyer in California - shows what state school advisors know.
Basically, that is a long winded way of saying I don't know what the hell all of that OH and ethanol and amine crap is.
All I know is that I use SM-90 in a modified DWC with every single res change. It works just like Hydrogen peroxide, without the burning foaming death that Hydrogen peroxide brings.
The first time I used SM-90, I noticed a near instant (<24 hrs) increase in the health of my roots. It eliminated some of the little flying bastards that were camped out around the base of the plant as well as dead roots.
In addition to SM-90, I use FloraNova (bloom & grow - depending), Floralicious bloom, calmag +, pro-tekt silica, and once or twice during flowering Liquid KoolBloom.
I have never noticed an adverse reaction, either in smell, feel, pH, or overall look of the plants or roots with any combination of the above nutes with SM-90.
So is this sm -90 back on the shelf, in my part of cali there selling mm-2000 instead saying its the same different label, anyone else seen this?
Yeah it is back on the shelves, but I had a store tell me the same thing because they didn't have the sm-90.
I don't think they are the same, but the link to the msds sheet is down on the Grotek site...
