Is Using Reverse Osmosis (RO) Water Useful In Growing? – Overview & FAQ

Reverse Osmosis and the modern high-tech Cannabis garden. Today on Lex’s World we discuss RO Water Purification and whether or not it has a place in your garden. You must do a cross analysis of both the water quality you’re dealing with out of the tap and what you’re hoping to achieve in your grow.

  2. JUNKFOOD PRODUCTION on May 15, 2022 at 6:41 pm

    My water is at 130ppm, and I can assure you that is really bad for my plants ! My water is full of calcium and lead.



  3. LunaLogicRadio on May 15, 2022 at 6:41 pm

    How bout you grind up a couple centrum vitamins into ur ro water?to make add those minerals etc?…



  4. Average Black Youtuber on May 15, 2022 at 6:41 pm

    I have an ro system and now I have alkaline water with less than 200ppm. I live in Flint MI



  5. Stoney Farms on May 15, 2022 at 6:44 pm

    I was thinking about RO water for hydro, but after seeing this I’m thinking I’ll try without. My water comes out of the tap at 110 to 125 ppm and 7.1 ph. Thanks bro!



  6. Petar Pan on May 15, 2022 at 6:46 pm

    Hi!I need help abaot making food for plants. If my EC of water 0,0 and when i put food in what EC is 1,7 but whan i have in water 0,4 in start and if i put food my EC 2,1 Is it that same or i should put less food in water? THANKS and sorry for bad English. Big hug

    my house is filtered from the water while the refrigerator is double filtered What would the best option be to use? I plan to use cow/horse dung into fertilizer what do you think the best option to use is? I will have to check my creek water around the cattle. I doubt using water from the cattle trough would do much of a difference but still what do you think between these?



  8. CAPTAIN CARIBE on May 15, 2022 at 6:47 pm

    Brilliant video top marks 👌🙏



  9. marcosteffano on May 15, 2022 at 6:49 pm

    My water comes out the same colour as milking a cow.



  10. Jeff Death on May 15, 2022 at 6:50 pm

    My tap water pH and ppm are very varied but around 300+ppm and up to pH 9. I bought an osmosis filter today for £36



  11. pimp2hoes on May 15, 2022 at 6:51 pm

    my tapwater is crazy like 700 ppm,would make sense to mix 50% tap 50%



  12. Tory on May 15, 2022 at 6:53 pm

    👍 thanks



  13. TheRealM00 The Original on May 15, 2022 at 6:53 pm

    bro my rain water is about 30 ppm isa this not just ro? i mea its still vaporised evaporated water right?



  14. dirigoelectric on May 15, 2022 at 6:55 pm

    My partner is convinced it’s the be all and end all. I have no use. I grow commercial as a caregiver. Unless you have pretty crappy water it’s a waste.



  15. Stoney Haze on May 15, 2022 at 6:56 pm

    I bought some cal mag and everywhere I see says add RO water. I make sure to measure the PH out of my tab water is that not good enough when adding Cal Mag?



  16. Aquatic ASMR on May 15, 2022 at 6:59 pm

    I have saltwater reef aquarium
    And i use ro di for both so it works



  17. Dave In St Louis on May 15, 2022 at 7:00 pm

    What Mineral solution do you recommend to add to RO to get the Micro/trace Minerals ?



  18. Aaron LaBranche on May 15, 2022 at 7:01 pm

    What about chlorine



  19. Judge TK on May 15, 2022 at 7:02 pm

    Well put young man. I have worked with water all my life.



  20. MrPuofke on May 15, 2022 at 7:02 pm

    So let’s say with german water you don’t even have to think about it?



  21. Muthrfuqrjonz on May 15, 2022 at 7:06 pm

    We should be drinking it, fuck the plants !



  22. Hogdaddy Glenn on May 15, 2022 at 7:07 pm

    Fortunately Lex I live in an area with some of the best water in the US….24 hours later I use it but always ph it….girls love it. Love your vids brother and have for years.



  23. Ege Çağan on May 15, 2022 at 7:09 pm

    Chlorine kills bacteria right? And we need them in our soils so i don’t see the point of using tap water.



  24. Dominic Lopez Novoa on May 15, 2022 at 7:09 pm

    I just use tap water thats a pH around 6.8



  25. Dustin Jay on May 15, 2022 at 7:12 pm

    My hose water comes out under 80 ppm. Perks of being Canadian!



  26. THIRD EYE ON THE SKY on May 15, 2022 at 7:14 pm

    They are cremating bodies with hot water only to let it flow back into the ocean and these are people who can’t afford burial costs and using raw sewage for tap not to mention smart dust radiation fallout and the list of pharmaceuticals rat poison and synthetics from men who are winning the war on intellect, empowerment, wealth, health and control we could give a flying f about the residual metals and calcium etc that is literally necessary to a plant after the poor filtration ran through miles of crusty rusty chemical coated pipes man I am not gonna finish the upload cause closed captions are faulty at best but what about conductivity of ions and oxygen what are benefits of cyclone filtration magnets or distillation? Take care man.



  27. Robert Mayo on May 15, 2022 at 7:15 pm

    I use Artesian water from the Adirondack mountains,it has a TDS readind of 62



  28. The Bear on May 15, 2022 at 7:15 pm

    So my ppm is close to 300 and I going to use am RO system. My question is should I add some trace minerals to the water?



  29. Mark Rich on May 15, 2022 at 7:16 pm

    city waters between 70 and 90 ppm. I use plenty of it.



  30. steven goulding on May 15, 2022 at 7:18 pm

    My water comes out at 400ppm I live in the UK so Yup I’m buying an RO tomorrow lol



  31. Troy Macleod on May 15, 2022 at 7:19 pm

    Huge fan joined weed tube growing dwc and getting rust spots but I’m using cal mag 3-8 ml I tried it all but still get spots is it the tap water?



  32. Paul on May 15, 2022 at 7:21 pm

    My tap water ppm
    Is 390 . I use two thirds revers osmosis and one third tap
    Water . This gives me a base line of about 150 ppm. Works out well



  33. hippo4g93 on May 15, 2022 at 7:22 pm

    My tap water in the caribbean is 90 ppm and we have shit facilities here



  34. Craig Anderson on May 15, 2022 at 7:22 pm

    Thanks for all the vids mate. Just wondering. If your worried about chlorine, is an air bubbly enough to eliminate the contanaments after 24 hours? Bubbling bubbling lol. Ppm really does let you know where you are in your grow and if you use a journal and the same strain you can really " dial it in " ( that’s the trendy thing to say) love your stuff man, stay safe everyone….



  35. Joe Shmo on May 15, 2022 at 7:24 pm

    The very good part of RO water is it makes it slightly acidic which is really what weed needs.



  36. Duncan Ferguson on May 15, 2022 at 7:24 pm

    I use r.o water in a danish dripper system, im scared to use normal because of algae and other stuff that can grow in hydroponics



  37. Justin Rodriguez on May 15, 2022 at 7:24 pm

    THose Co2 cans suck they last like 2 days and barely add any co2 and the cost a lot for something like that. I wouldn’t recommend



  38. Josh Irvin on May 15, 2022 at 7:25 pm

    So in short it is not good to use bottled water for your plants….correct???



  39. Nibbles D. Biscuits on May 15, 2022 at 7:25 pm

    34 ppm straight from the tap in my small town by the sea. 👍🏼 6.8ph



  40. Inventor Down The Rabbit Hole Network on May 15, 2022 at 7:26 pm

    there are r.o filters that give alkaline and minerals also it’s 2020 the future is now .



  41. Cooller on May 15, 2022 at 7:28 pm

    RO water all the time! no matter where you live, how hard water you have, or not… it’s best to clean it and put everything back in… the third part of nutrients is really not a problem, not even a financial one, however, you can now follow the instructions on the label and get the ‘scientific’ results within your own grown also with good light and controlled environment you really can’t have a nutrient issue, it’s impossible unless the manufacture of your nutrients lies about the dosing… the dosing actually works with 0 EC water so that’s the reason why every ‘growing’ influencer is suggesting use fewer nutrients than the label says… it’s also really worth for beginners because everyone can now address an issue immediately without a doubt… overall if this all you gain with using RO water why wouldn’t you if it cost you only one more bottle of nutrients to buy?



  42. Eli Skull on May 15, 2022 at 7:29 pm

    but if you are already providing nutrients to the plant then wouldn’t RO be the best thing to use



  43. Fribit LoveLoad on May 15, 2022 at 7:31 pm

    My city water in uk is 365 ppm , basically very hard , some people wouldn’t wash their dishes with anything over 150 ppm



  44. Torrie Landsman on May 15, 2022 at 7:32 pm

    water that falls from the sky (rain,snow) is distilled water it has nothing in it!
    I used to catch rain for my girls and it tests out to 0 ppm less in it than most RO.



  45. Agent Sancho on May 15, 2022 at 7:32 pm

    Came here to learn about a walter filter system for my faucet. Then I left with tips on how to grow the dankest weed. 😂



  46. Thomas Eidstø on May 15, 2022 at 7:33 pm

    Much love from norway ❤️



  47. Joe Shmo on May 15, 2022 at 7:36 pm

    You forgot chlorine which comes in almost all water you are getting in the city, and chlorine kills organic matter which is normally a good thing but not when you are watering your plants.



  48. james arundel on May 15, 2022 at 7:36 pm

    Yeah it makes deficiency as soon as the nutrients are leeched off. See it done it. My tap is 600ppm not much needed in veg.. how about using it in the flush cycle



  49. james bond on May 15, 2022 at 7:36 pm

    we’re in USA my rain barrels ppm at 0-6 depends on dust,dirt,etc. our tap water is 250-400 ppm. Anyhow anything over 100 ppm water wise you’ll need reverse osmosis and micro nutes etc. Indoors you have the power over the light,temp,air,etc. And with RO the water. Fast tip he didn’t bring up you can ad one cup of tap water into 50 gallons of RO and get those micro nutes back with a ppm of 0-5 depends on how much you ad to tank.



  50. 1mouseman Jomama on May 15, 2022 at 7:38 pm

    Tap water ppm here 560 lol
