I just finally got an answer back from my local city water utility.

Quote: "The average hardness last month was 7.2 grains. Hardness varies throughout the year from 7 to 10 grains/gallon"

When asked about total dissolved solids - Quote: "We donít test for Total Dissolved Solids so I donít have any values to provide you for that." (insert eye roll here)

I guess I'm mixing RO/Rain/distilled water with my tap water. The question is at what ratio.

How many plants do you have and how many gallons do you use in a week?

I have five orchids total. Cattlianthe Secret Love (3" pot), a Cattleya walkeriana (5"pot), Rlc. Hsinying scarlet (3 cup plastic tub) and the two NoID Phals (one regular size 5 " pot and the new mini).

I don't really keep track on how much I use for the plants since there is several other types plants about the house besides the orchids.

I'm sure I'll get in trouble for this. I use a pitcher water filter and I test the TDS and the pH. I take a couple kitty litter jugs and I run my tap water through that filter into the kitty litter jugs and that's what I water with. My water is very hard and there's a lot of iron in it but my orchids seem to be thriving. I know that there are more technical ways to do this but sometimes I feel that overthinking it is just unnecessary. I have over a hundred orchids and it takes me six gallons of water to water them and I use that twice a week that would be a total of 12 gallons.

Default Good humidifier Option!

Unfortunately I'm going to need to change the humidifier because it only lasted for 7 hours :/ .. It did up my humidity from 28% to 53% though so I'm hoping if I can find a good one that this will help my orchids a lot

Here's a picture with the changes as well as the label of the fertilizer I used: Imgur: The magic of the Internet


I know I still have a long way to go but I already think your advice will help my orchids a lot

Edit: removed video and added attachment of picture
If you are still in the market for a humidifier, the Vicks filter free cool mist has done a very good job for me. I have two of them and they are fairly cheap. I got mine from target in store and had them price match the target.com price of $35 a piece. Well worth while. I was going to look for pricier ones but then I was reminded the likelihood that after a year or so you may end up chucking it and buying a new one due to mold/mildew accumulation!

If you want to know the TDS, invest in an inexpensive meter (and a calibration solution for it, so that you'll know that it is working correctly) Then test your water now and then. Many water companies get their water from multiple sources, so TDS is highly variable. (Mine may be 180 ppm on a very good day, 450 on a very bad day, average usually in the neighborhood of 250.) You don't need to stress over exactly what you're using on the plants, but knowing what you have would give you a better idea of how you want to mix it with pure water. The other consideration on using part tap water is to have some idea of what minerals comprise that TDS... if it is mostly calcium and/or magnesium carbonate/bicarbonate, most plants can tolerate it quite well (and benefit from the calcium and magnesium, which are necessary in modest quantities) If it is sodium chloride (salt, as one would get from sea water intrusion) then you would not want to use it on your plants. That info should be in your water analysis.
