That seemed odd to me. So, I googled it.

Reverse osmosis was originally developed to make drinking water from seawater. Your system is equipped with a membrane that will be very effective in reducing sodium levels normally found in ground water or softened water.

Seemed odd to me too. Of all the salts that an ro membrane filters, sodium is the exception?

well damn i stand corrected!! maybe I will have to look into that.. although distilled water is only about $1.50 a gallon but still a pain in the ass buying all of it lol Thanks!

Yeah, I run two humidifiers in my 4x4 tent during early to mid veg, and then drop to just one in later veg and early flower. I used to buy bottled water too. Pain the ass for sure.

Systems cost a bit, but well worth installing, or even having it installed if you need to humidify the environment for growing.

Yeah I think I will have to invest in one! I cant taste any salt in my water at all but for it KILLS humidifiers for sure.

I live in a pretty rural area so I think I am going to just get a system, thank you for the heads up!

Have you ever considered rain collection? Weve been off the RO for years now and only from rain collection; its very close to RO and works really well; also wont waste ground water. We do it from one drain of one ceiling with very irregular rain fall though when it rains it rains big. You can also may even setup tarps. Or if your spendy some solar panels with a rain collection provision. Any surface works. Just a though and obviously depends on your property and climate but always good to think out of the box :)

For humidifying theres also diy solutions; any piece of cloth drying in the grow area will create humidity, and more so with a fan on it. A blanket or similar of a high absorbing fabric hanging up with a fan on it, with one end sitting in a bucket of water can atleast change the dial somewhat

While rainwater contains no minerals, it can contain dust and pollen. Doubt that would be good for any humidifier.

Not sure on rainfall or typical RH in your area, but I would never, or rarely be able to collect enough rainwater in the semi-desert area I am from to keep my humidifiers supplied to humidify my single 4x4 tent with 4 inch intake, and 6 inch exhaust when in early veg.

To maintain negative pressure in my tent, and keep humidity in line with VPD or somewhat close, I tape over the intake considerably, slowing intake.

RO systems aren't completely maintenance free, but changing filters periodically is a small price to pay for having suitable water on tap to fill humidifiers. I'm not the greatest at DIY, but an RO system will solve the problem you are having.

I grow in SIPS also. Not Earthbox, but City Picker SIPS. Do you grow in tents, or do you have a room you grow in?

I would be worried about sediment from the shingles also and all the pine stuff I would install a filter but I think not consuming all that sodium would also be good for me and fam. Our water is amazing except for that one thing. We have a very deep well and get the water tested every year.

Are you exhausting air from that attic space?

That depends on which way Im trying to go with vpd. Sometime exhaust out the window if Im trying to lower rh and then scrub and recycle air into the room when trying to raise rh. I did pretty good last run keeping the area close to right but it took constant monitoring and changing. Im lazy

Just be careful. Humidity exhausted into an enclosed space will cause mold. Don't ask me how I know. Lol
