EASY Beginner GUIDE & TUTORIAL Introduction to pH & TDS meters for Dosing Nutrients #ninjaorchids

👕👚Fabulous Orchid Swag! 👇🏼🤩 #orchidfashions Https:/teespring.com/stores/ninja-orchids-3

Thank you Nina in airing the most important and highly useful topic of Ph and TDS in orchid growing upon my request.I wish all orchid growers in different parts of the world think seriously about this topic after watching NINJA ORCHIDS You Tube Channel.

Hi Nina! Wonderful informative video, as always. As I have told you before, I learned from you how to properly use pH and TDS meters in cultivation of orchids. I implemented your techniques a year ago and my orchids are thriving. I knew they weren’t happy for years and I struggled to find a solution. I can only surmise it’s your expert techniques. Thank you so much for sharing. And I’m sure anyone who follows your instruction will be rewarded too! 🌹🌹🌹

hi Nina, you are smack on target with t his video. Kudos to you for sharing your wealth of orchid knowledge, Thank you

BRILLIANT video Nina, and really well explained and informative video about the right water quality being so important, when I lived in the south of Ireland our water was very hard and with a very high pH of pH9.5 a lot of my cacti struggled and I had to use rainwater that was a pH of 5.5, Here in Belfast our water is nice and soft at pH6 and the cacti do so much better, I still use rainwater for all my Phals and Tillandsia Air plants and Carnivorous plants at pH5.5, the TDS meter looks a fantastic tool for testing the nutrient and salt build up and preventing over fertilising, you are so amazingly knowledgeable Nina, thanks so much for sharing with us and sending you lots of love and happiness and PLANT POWER from across the Emerald Isle to Spain for a fantastic weekend ahead XXXX <3

Hope you're having a great weekend, Nina ❤. Thanks for showing us the readings you take whilst caring for your orchids. It's always a good reminder that the enzymes that act as catalysts for the metabolic processes occurring in plants (and all living things for that matter) are adapted to and function within very specific pH ranges. Extreme variations can definitely lead to damage. Absolutely worth bearing in mind. These tools can definitely help to ensure consistency and minimise fluctuations when caring for our plants 🪴 ❤.

One correction, a TDS meter cannot measure organic matter, it is by definition non-conductive in solution so there is nothing for the TDS meter to read. TDS meters work by electrical conductivity, which is then translated to TDS. Anything in the water that does not have a charge will not be measured. If you are using a urea Nitrogen fertilizer, you will get a much lower TDS reading than the actual because urea is organic and does not register on a TDS meter. I have two fertilizers that have the same composition (N, P, K and all other nutrients identical) except one is a urea (I use it outside), the other is nitrate and ammoniacal N (used on houseplants). If I measure the same amount of each into water and test the TDS, the urea reads roughly 1/2 the TDS because it is not reading the urea component. Easy experiment to do at home, take a glass of water (tap is fine), measure the TDS. Add an amount of sugar (say a teaspoon) and stir to dissolve. Take the TDS reading again. It should be nearly the same if not identical. Repeat using table salt. The TDS should be exponentially higher with the salt.

🦒💐👏 Great video, many people are still not aware how details such as these are important. It may seem complicate at first but once understood it becomes so easy. Kudos from stormy Portugal which seems to be our new climate. The 3 days of sun we had prior were such a delight 😂❤❤❤❤

Nina:_OrNinja: Great comprehensive information! Thanks, Sherrii San :_Ninja:❤

Very interesting and lots of info to take in to consideration as well. Still having sleep issues so YT has suffered my non viewing time as pages of vids line up.... I think doing away with a few of these channels won't hurt that much. 😂. Hope you had a good one Nina. 👍🏻 🦇

Hi Nina, thank you for this video! Really was easy to understand this video and it made perfect sense to me. As usual you’re wonderful at helping demystify orchid care . I’ve been watering my orchids with water from my dehumidifiers , the tds is fine but I’ve never actually tested the PH . I’m certainly going to have a little play with my water and see what the measurements are with a little more attention . I collect rainwater too, so I’m definitely going to be doing some dip testing before watering my plants this weekend. My curiosity has been piqued & I have a way better understanding of why it is I’m checking in the first place . Bought a meter without any understanding of what I’m meant to be doing. 🤣

Baby, interesting video I’ve never had one of those gadget things. I wouldn’t know where to start. Thanks for the very good video your knowledge of today❤❤😊😊

Another well explained video. I may well might have slowly killed off my collection without these monitors. New fertilizer comes up at ph of 4!!!!!! And over 700 ppm. Just goes to show that different batches of the same fertilizer may have different characteristics. Thanks again for sharing your wealth of knowledge 😘

I’m slowly becoming more comfortable with the science of nutrition for orchids. Your videos have taught me the most. My other source of information has been my husband who has 46 years of experience in crop production (yes, we are that old 😅) including water quality and nutrition. The one thing I haven’t gotten is a pH meter. I know the ph of our water is about 7.4 from water tests done in a reputable lab and have checked the ph after adding nutrients using just litmus paper and adjusting with pH Down. I’ve looked online for pH meters and have been discouraged about their accuracy when I read the reviews. Do you or any listeners have advice about finding one that is reasonably accurate and doesn’t break the bank?

I've been thinking about PH testing different media combinations such as bark and coconut husk or sphagnum moss and leca without any orchid inside. I can also see how long it will take for each mix to dry out. I think this would be a good first step for any beginner.

700 ppm on your tap water? that's a lot :) look at me complaining with around 250...

Hi Nina, I need to learn more on this and get a TDS meter one day. I already have. PPM reader. I have some Cattleyas that the canes are like wilted and soft… so weird. So I added some epsom salt and calcium to see if that help them. Hope they harden off. What could that be? 🫣😆 Great video.

I thought my 300PPM tap water was too much... 😵‍💫 I have one question. How much does the substrate in which the orchid is grown affect the PH? I've heard that shagnum moss slightly changes the PH value in the pot, to slightly acidify the medium. How accurate is that? Do we have to change the PH based on the substrate in which the orchid is poted in? Also, i don't understand one thing. When we flush the pot, does it matter what the PH value is?

Hi Nina. I love your videos and want to really learn how to fertilise correctly. Out of my 50+ Phalaenopsis only two flowered for me year 😢. I purchased a Ph meter and brought the level down to a 6.3 with the use of PH down and then added fertiliser. Not sure if that is correct procedure. I do have a TDS meter and have checked my water before doing the above and it was around 78. How much fertiliser is needed to bring it up to 300ppm. Is there a site that explains the process in a pdf form. I am in my 70’s and didn’t quite understand how to do everything correctly and in which order. Cheers from Australia xx

I was watching your video and wondering if your fertiliser is unusually high tds or mine is unusually low :D I normally do 150-200 tds for those requiring a bit less food and 200-300 TDS for things like Phalaenopsis, Anguloa, etc with Cymbidium getting a double dose. I now wonder if I'm underfeeding. Is there a difference in strength when comparing semi-hydro/inorganic and organic (most of mine) growing?
