How often do you use silica personality

If anyone's still interested and using Potassium Silicate as pH up until harvest. I may have found some relevant information.
Says enough for me, that I'm going to stop using it a few weeks before harvest from now on.
If only to be on the safe side.
As said in previous comments. If anyone has any data to share, like sample reports for contaminants etc. in finished, smoke-able product. That does, or doesn't support Silicas use in such a way, I'd greatly appreciate it. As I'd like to still use it up until harvest, if it's safe enough to do so.

My own 2cents is it should be safe and mostly harmless on edible crops. But can have the potential to be dangerous, if ingested in large amounts.
The question still is regarding smokable products. It seems mostly unexplored.

I'll quote some of what I think's important and leave the link here too.

"4. The effects of the substance on human health.

Applications of potassium silicate pose a risk primarily from inhalation or ingestion of silica-rich compounds. Respiratory problems in the agricultural sector due to inhaled dust are a proven concern (Schenker 2000). Decades ago, it was shown that dust arising from storage and handling of wheat grains contained particles that were believed to cause respiratory NOSB TAP Review Compiled by UC SAREP Potassium silicate - production September 4, 2003 Page 5 of 14 ailments (Baker 1961).

Burning of high-silica crops, such as rice and sugarcane, have been problematic for worker health in the past (Boeniger et al. 198. There is also significant indirect evidence linking ingested plant silica and human cancer (Sangster et al. 1983, Bhatt et al. 1984, Hodson et al. 1994), but there currently is no connection between plant silica and inorganic silica sources. Mitigation of health risks associated with respiration of silica-laden dust can be achieved though proper use of personal protective equipment including a NIOSH-approved dust respirator where dust occurs. No carcinogenicity, mutagenicity, or developmental toxicity data are available for potassium silicate. "

I have ran Potassium Hydroxide as pH UP instead of Potassium Silicate and noticed absolutely no change in plants given Potassium Silicate (silica) instead of Potassium Hydroxide. I think this is mythological bro science that stopping feeding a few weeks before harvest will make any measurable difference to the end product.

"Silicon is a mineral present on earth in abundance. The element makes up about 28% of mineral soil by weight."

there was a great article by manicbotanix (it's now a pay site apparently) about Si and he recommended to use from start to finish. and he had some quotes from scientific papers to back up his claims

I just started watering with well water after testing ph. Dr Wendy Zellner From University of Toronto mentioned there should be a decent amount of silicon from well water that your plants could use.

i've been using this for the last few years from CES Bulletproof Si
5% Silicone Dioxide (Si02) derived from Sodium Silicate

he (she maybe?) had a lot of great articles about some of the more advanced aspects of growing too. i guess make that $ if you can!!!

Yup unfiltered water will certainly have SIlicon in it, the earth's crust is made of like 80% Silicon.

@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...

Combined effect of silica dust exposure and cigarette smoking on total and cause-specific mortality in iron miners: a cohort study - Environmental Health

Background Both cigarette smoking and long-term exposure to crystalline silica dust were reported to be associated with increased mortality. However, the combined effect of both factors has not been well evaluated. Methods We investigated a retro-prospective cohort of 7,665 workers from one...

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.

I dont think burning plants that used potassium Si could convert to crytalline form of Silicon dioxide. Silicosis is caused by breathing in dust with crystallized silicon dioxide. Which is totally different. Your bigeest health risk is smoking and unfortunately smoking cannabis will cause you much more of a health risk than these theoretical issues with fertilizing with potassium Silica. This is a soluble form and wont get trapped in peripheral airways. There are no adverse health effects, that I am aware of especially to your lungs with edibles.
