So way, way back, circa 2021, there was a lengthy discussion about “the best” silica supplement out there.
We all pretty much universally arrived at “potassium silicate” - also known as
And so on.
Then came @Hellraiser - who suggested a different form of silica - Monosilicic acid. Specifically the product he recommended was Alchemist Stout MSA, here:
The why is as follows:
Potassium silicate is not readily absorbed by plants. The silicon particles are too large to be immediately bioavailable to your roots. Microbes break down potassium silicate and, in turn, create silicic acid for the plant to uptake (boosting cell strength etc etc). This is why you need to add silica from the onset of a grow (if using a soilless medium or reusing soil from prior grows) and continue use of silica + microbes to maintain healthy cell structure.
Monosilicic acid, on the other hand, is a shelf-stable version of the acid you rely on microbes to create in order for your plant to use the silica. In short, Monosilicic acid (or MSA) is immediately bioavailable.
I suspect that’s why Hellraiser liked alchemist stout so much.
Now Impello Biosciences - creators of Tribus, the G.O.A.T. of microbe supplements - has released their own MSA, called “Dune.”
I realize this reads like an ad - not really my intention, but I’m excited to see more MSA varieties hit the market. I have noticed that my coco gals don’t always break down the potassium silicate as quickly as I’d like them to - MSA will help us non-soil folks see fast results.
Use the Dune15 its $103 ish… its 1ml a gallon…thats a metric shitphuk ton of silica. like 500 plants worth.
I’m using GG and Elite 91 (this crap is $250/L), ok its got B, Mb, Mn and a bunch of aminos that crank the biostim…but the GG kicks its ass…Si is a biostim…
Yall over her dropping money on these products while im still mixing de in with my soil lol i feel like I’m in the past but the cost of de to some of these products especially empello is a night and day difference lol I felt robbed as hell when i bought the smallest bottle of tribus original 100ml goes quick for 30 bones a bottle lmao
I can’t say that there might be better options, but I use Bloom City Silica Boost, which is potassium silicate derivative. It makes a noticeable difference in my plant’s structural strength.
I found this on Hydrobuilder:
" The best form of silicon is mono sicilic acid, also known as ortho silicic acid. Unlike potassium silicate, its 100% available immediately upon feeding, which allows you to accurately and reliably dose your supplement.
Because silicon is an immobile nutrient, it cannot be moved to other parts of the plants once taken up by the roots.
This means you need a steady flow of silicic acid to take full advantage of the benefits silica has to offer.
When using silicic acid, you can rest assured your plants are getting this vital nutrient throughout their entire mass. You won’t need to wonder whether it is working or not!"
Finally something worth buying on black Friday. Probably be a good time to pick up the uv bar and exhaust/controller I’ve been wanting. This year my gg4s should be less than a month into flower on Black Friday. Like it’s meant to be.
