So I’m wondering about arsenic in water and how cannabis may or may not retain a great deal of it. My city water, mind you it comes from aquifer. Has an arsenic level of 8 ppb the legal limit is 10 ppb. I’m wondering if my plants will retain that and continue to do so and increase the levels by the time Im ready to to harvest and then consume either it be inhaled or in ingested. No I haven’t been giving my plants this water just yet but buying ro water is getting a little pricey. Sorry if this topic has been brought up before I seem to have been unable to find it.
I don’t know specifically about arsenic but if you’re concerned about your tap water for the plants you plan on consuming, are you comfortable using your tap water for anything you touch or consume?
This is a good read, I’ll let you be the judge as there isn’t a clear answer unfortunately
I’m pretty comfortably drinking my tap. It’s at 8ppb. Beneath the legal limit of 10ppb. I cock with my tap and drink it. But I’m more concerned and wondering about the levels building up in the plant over the grow. I read somewhere that over 100ppm in consumable crops is not good. Also read combustion with levels that high is extremely bad. As for me I believe I’m able to flush out that arsenic no problem but the plants retention and soil retention I’m not so knowledgeable about.
Interesting read, almost makes me want to know which strains are the soil suckers of heavy metals. You know before purchasing.
Yeah I’m going to stick with RO water. I had to flush all my girls and I didn’t want to use ro water so I just used my tap.
Again use your own judgment but the difference between ppb and ppm is ridiculously huge!
If Legal limit is 10ppb (parts per billion) and 100ppm (parts per million) is the unsafe mark, it would take alot to reach that.
For example 1 ppm = 1000 ppb so, 100 ppm = 100,000 ppb.
At 8 ppb that take a 125 x increase in concentration…
I’m not exactly a scientist but that seems very unlikely to me such an accumulation could occur.
