How often do you use silica personality

Sorry about my grammar and punctuation if ive missed anything out that could help please ket me know

Light is spider farmer 4000 at 80%
I need to measure distance when i find my tape but lux on phone app says 40000 at plant tops
80 to 82f light on
70 to 72 light off
Rh I've seen it at 75 lights on but I need to set up my dh and was thinking set it to 70 and then when I get my Ir temp gun get it dialed in to the leaf vpd

Currently feeding at 1.5 ec but I've only used these nutrients a few days now

My plants are photoperiod clones in early veg

So I'm growing in coco and perlite I will post nutrients content at bottom I'm using hydrosol a powdered nutrient that you use to make up Nutrient a and b I was thinking of adding liquid silicone by growth technology just wondering how often people use I was thinking maybe use for 1 week then off the next and stop at the end of stretch also I read online that I wouldn't need to use cal/ mag with this hydrosol you just adjust the ratio of the a and b so I'm guessing just start adding slightly more nutrient a but I'm not sure I want to do it that way I have a 3 stage filter and my water comes out at 0.2 ec what would everyone recommend to bump up my ec too using just a cal/ mag I read somewhere to go to 0.4 ec but thought I'd check here because I can't remember where I read it any help will be much appreciated

What do the plants look like? If they're healthy just keep doing what you're doing. Why change anything?

if i was growing in soil i wouldn't use it at all. i grow in coco coir, so i use it twice in veg, and once at the beginning of flower.
i'm not convinced i need it at all, but it's one of those things that can't hurt, unless intentionally misused, so i give them a dose at about 3 weeks, and another at 5 or 6, then the first watering they get once they start stretching, after they're flipped.

I was thinking on my next run I would give some the LS and some not but for now was going to add it

Is that just one watering or is that your resovour for several days

Makes a good pH up have to say. I'm using OMRI certified potassium silicate.
I believe you can observe improvement from using it. Convinced I've seen the difference myself. If only a little.

Personally I take the "availability" of Si products with caution. (the same is said for garden lime)
You don't necessarily want or need an Si product that's so readily available, as some Si products are.
I don't ever go over the manufacturer's recommendations either.

If it helps against pests/disease, whilst producing stronger, more tenacious plant fibres, then I'm all for it.

My only concern about Si is in end product.
Will using Si products up until harvest adversely affect one's health?
Is it legal in commercial operations to do so?

It's a genuine concern I do have. If anyone can inform me.
I've seen the general advice is to stop Si use a few weeks before harvest.
Using 1mL/10L solution.

Tempted to run it until harvest anyway, from now on.
Would appreciate input from any person who knows.

Cheers.

i hand water, so its just one dose, then another about 3 weeks later. since i only do it twice, i use the heavy dose directions. if i was going to use it regularly (although i can't imagine why i would) i would probably only use about half of what they recommend as a regular dose.

Si is just micronized sand...the plant uses it to build stronger cell walls, which make it harder for pests to penetrate, and makes them a little more drought resistant. i don't think it really effects quality, one way or another, as long as you're taking care of your plants properly.
my plants have a tendency to sag as the buds swell up and get heavy, and the silica seems to make them a little stronger, is the only real reason i use it, but honestly, that could be my own perception bias.

I use potassium silicate in a foliar on my outdoor grows. It has been shown to have effectiveness against PM and mold when used as a foliar.

"The nutrient solution amendment of 1.7 m M Si and foliar applications of Si of ≥ 17.0 m M decreased the number of powdery mildew colonies on all three cucurbit species compared with the controls."

Yes I have used it for ph up when I use that way I always dilute in water then add water as needed and if adding direct to reservoir I add it first and wait 5 min after stirring and i don't add cal/ mag then

It can be used as a pH up since it's so alkaline. I'm always curious what people are using for nutrients and what their starting water pH is when they need to raise the pH. I've never in my life had to raise the pH. Lowering it is the only thing I've ever needed to do and that was hydro or when mixing nutes for coco. In soil I don't even bother checking.

Ok thanks I've just added at 0.5 ml per liter it recommends that for hard water but i think I should use the 1ml per liter for soft water or maybe it should be slightly more because I'm using a 3 part filter and my water is already soft apparently but I haven't checked it yet but it comes out the filter at 0.2 ec

@xtsho @Roger A. Shrubber

Thanks for your responses.
I'll emphasise correctly the question I'm asking.

I've been informed by someone who knows their chemistry, that Si maybe able to form chains in the plant tissue, which might adversely affect a smokers health.

My logic says 1mL/10L of solution isn't enough to really worry about. But I want to be sure.
Won't be using it up until harvest if it's potentially harmful.

I'm not sure on that but I'll definitely look into it and maybe see if can find out if it makes it's way into the stems of buds

Maybe it's non combustible? Looking at a similar products MSDS.
Honestly unsure.
Particles in the smoke maybe still a problem if they're fine enough to be carried?

Would much appreciate if you pass any info you find my way. Thanks.
I'm using it strictly in nutrient solution. No foliar applications.

Know if it's legal in the medical canna industry to use silica right up until harvest?
No-where I can find online that specifies.

Here's some of the MSDS -

"Hazardous Combustion Product If involved in a fire, not combustible, but may support combustion of other materials. Some gases such as phosphorous oxides may be released."

It really helps when you give the plants a beating, and supercrop the heck out of them. Especially when growing hydroponically. Not sure I ever watered soil plants with it. Harder to damage branches when your bending them around, and high stress training with trellis nets, IMO. I tried side by side, and the Si supplemented plants were more pliable, and rubbery like.

I wanna say it takes longer to decompose.. like, the branches that i pitch out in the woods don't break down as fast. They'll still be there in the winter after the tree leaves rot away, but i' don't know for sure. Maybe its just because my hydro plants were always so much bigger..


I actually quit using it last year or so. I don't buy any supplements anymore, and don't plan to buy another bottle any time soon.

Unless they sell it dry, so I can mix my own or something. I'm not paying for water. I'll have to check..

I stopped using it a couple years ago. Haven’t noticed a difference personally myself.

@Thisguy-4'

To cut a story short, I've used Si right up until harvest twice so far, with no obvious harmful health effect.
I've also observed better smell, resin and more healthy plants from doing so with the same clones.
I'm convinced myself that Si does work.

Though...

I get it...we're not necessarily speaking about crystalline silicate.
Though if speaking of combusted plant material, who's to say "more" crystalline particles wouldn't be present in the smoke, if Si was supplemented?
And if levels of Si in the inhaled smoke are higher, is it much more harmful?

Anyway I'll stop crashing the thread.
Not a topic to be ignored if it could be harming peoples health.
If I find a definitive answer elsewhere, I'll post it up.

Cheers.

I noticed a big difference after I stopped using it. My nutrient solutions stays way more stable, and I don't have to adjust anything anymore.
