The RO from the our store machine tests at 20ppm and the bottled water I buy tests at 15ppm. Been drinking it for years.


Seems like I might need to re-adjust my line of thinking on this.

I still think that I already lack micronutrients and that my plants are probably fed better than I am, RO water probably won't do me any favors.

Whats the difference between ro and bottled drinking water? Both are sold at the store for human consumption and both test under 20-30 ppm. Is the doctor trying to kill me? They serve ro water in the waiting room. LOL I call fake news bs
So I used to run a factory that had a e-coat paint system we used RO and the manufacture of our system said it was safe to drink but yes you have to get the mineral content somewhere - they also said could cause serious shits for some-

I give my seedlings ro or rain and they love it because they are in cocoloco which has everything they need. When they get bigger I mix with 400ppm tap water 50-50.

The machine at the store that fills the big bottles claims to be RO water, its sold for drinking and is under 20ppm. @ 35 cent/gal its a good deal. The bottle of niagara I'm drinking right now just tested at 7ppm.

Just keep in mind that water from a public RO machine is only going to be as pure as the store keeps it clean. If it's dirty, those impurities will transfer into the water. It's cross contamination.

Technically speaking though, both distilled water and RO should be 100% mineral free ... In the real world? Not always ...

Buying a filter for your drinking water is common :p most people use BRITA's even in first world countries. Unless you enjoy fluoride and chlorine that is.
Even cheaper possibly are those Brita filters that @Shaded_One suggested. Common item that can be found at most any big box store.

Yeah RO is often up to 40ppm in places like that and rarely below 20ppm. They don’t usually run RODI that’s usually 0-2ppm with new filters

True story here ... I was on the road about a year ago repairing some industrial equipment. I asked about the lime and scale in the piping. They said that they use RO water, there should be no minerals in the system. I asked how often are the filters changed? Answer was ... never.

I hope that adds clarity to the issue.

If your in Canada you cant really beat this.

Aquatic Life RO Buddie Three Stage Reverse Osmosis, 50-Gallon
https://a.co/d/haoqARK

In USA here. You can get an RODI unit for $80 or RO for $70

I bought one of those & sent it back because of too much waste water & replacement cartridges, Then there's the added work of making the RO water....I found a source for 16 Gal of 0 ppm $6.50 + new caps on the bottles if I need for another $1....

If I need to replace filters every so often then there's an ongoing cost any ways. Along with everything else that needs to be dealt with, picking up water once a week in the winter or once a month in the summer for my dehue's water is easier and close to the same over all costs for me.

I bought some distilled just to mix 50/50 with tap until they grow a bit and get stronger. Very slow growth right now.

So what do you guys do if you find a fungus gnat in the tent?

The most common source of fungus gnats in an indoor grow is from the soil. The bugs were present in the soil when you bought it. Speaking only for myself, I've never had the issue with either Fox Farm Happy Frog or Ocean Forrest. I've also never had issues with Roots Organic "Lush" soil. I have had this issue with brands like Miracle Grow. Others may have had different experiences.

Edit: Not a bug guy either but I don't like anything that flies out of the soil.

Yeah I figured it was probably from the soil. A buddy of mine had some from his OF or HF so maybe it’s the store we’re buying it from? Hopefully it won’t turn into a swarm of them, but I sorta expect it to. Grabbing yellow stickys tomorrow to catch the little bastards. Got nothing against little bugs as long as they stay where they belong… outside and off my plants haha.
