Sorry for responding to him in the first place, it seems to just give him energy… if you actually want an answer to your question you might need to start a new thread. This one is apparently now @OldUncleBen’s soapbox to explain to everyone in great length how everything they’re doing is stupid and he knows best. It doesn’t actually matter what they’re doing, just that he knows best.

Hmm. I wonder if maybe this holier-than-thou attitude, that we’re all “swine” who desperately need you to give us your “pearls of wisdom,” asked-for or not, contributed at all to the great number of trolls and haters you had back in the day. 
Anyway, I’m gonna let you get the last word now if you have any - I’m sure it’ll be devastating - and then sit back and watch in amusement as you slowly continue having this fight in every other thread you visit.

Just for kicks, I did a Google search on silica and the “benefits”. As usual, most of the results came from the dozens of vendors that hype it for monetary gain. The cannabis industry with it’s multitudes of inexperienced growers, many who have never grown a plant before, get targeted. does silica make plants stronger - Hledat Googlem
Then there’s Advanced Nutrients LOL.
The question remains in my cynical mind, “is cannabis a silicon accumulating plant species?” I still maintain it’s beneficial vs essential to such crops as rice. Do commercial growers (those with acres of cannabis under glass) apply silica as part of their productions routine?
There is research on Japanese studies of rice. Rice is a monocot, cannabis is a dicot. Not that it may or may not matter, just seems to be apple and oranges.
Some plants have high accumulation of Si in their body, e.g., rice, sugar cane, and bamboo, and, for these plants, Si is quite beneficial. All these findings point at the fact that Si has to be counted as an essential plant nutrient and not only beneficial.
^ monocots
There are no miracles for growing cannabis. What’s important is understanding what makes a plant tick and mimicking, providing, the soil profile, temps, photoperiods and other cultural requirements your faves are indigenous to. DO THE BASICS. Oh, and let’s not forget patience and a bit of luck. One hit of mites like I had recently and your plants are toast regarding top production. Luckily, for this Cannacopia Lapiz Mtn. indica, it was just packed with leaves. I got the mites under control with blasts of water and an application of Forbid 4F. By removing handfuls of damaged leaves recently I think I still have enough healthy leaves for good photosynthesis.
I think this lady has about 2 weeks or so to go. All it gets is rainwater. Is being fed with Osmocote 15-9-12 I applied back in December.

Do not worry
I actually got answers through this thread.
And some very valuable information. In the @shag thread there is a picture with instructions on how to get a certain ppm with agsil25. And this product of mine has identical proportions

If you want to learn rather than troll, feel free to look up and read the dozens of “papers” I have written over the years or ask for some advice. I’m hear for my fellow gardeners, have always been. I’ve grown about every kind of plant material you can imagine both on a personal and commercial basis. Where is uncle ben? | Rollitup

Hey @OldUncleBen
Have you seen this?
This is some good science, some of it is a compilation of what I have found and the intellectual part was written by a friend of mine.
Hydroponics growers seem to benefit the most from added silica.
Check it out if you have the time.

Thanks for sharing and the same thing I have used. I trust Dyna-Gro, and have used their products for decades. Their silica product is in a form that can be taken into the cells via the leaf or a soil drench too. Sure silica (sand) is pretty abundant in nature but is it in a salt form the plant can use?
My go to surfactant is NIS aka “non-ionic surfactant”. What the cons are rebottling NIS and charging big bucks for I buy by the gallon for about $13 USD from a farm and ranch supply. Another good sticker is Hy-Yield Spreader-Sticker. Like roses cannabis has a tough leaf surface tension to deal with. Sprays that do not contain a surfactant are useless. You’re just wasting your time and money.

Always add silica last is what I’ve always known. I think it’s to prevent locking out other nutrients. Also buy Agisil16 and you can make your own Protekt for a fraction of the cost. You can google the recipe. I just put it in dry a small amount at a time.
