ro water

Hi Everyone, I'm new to the growing scene, always been a back seat driver and now I'm getting my chance to be in the hot seat and its not going so easy.. haha Where do I start... I'll try and keep it brief and not overload with info. So the beginning was going fine, I planted 3 strains 2 each...

the set up: https://www.rollitup.org/t/setup.1054721/#post-16355858 So far everything is going .. ight. Lol. Started with four, lost 1 of each (one I think I knocked off the roots doing a nute change, other one not sure about, stress?) replaced the two I lost. 2 wedding cake, 2 Girl Scout...

Hey ladies and gents! starting a fresh grow as I had all males last time for my first ever grow I’m germinating right now but I’m switching one major component. I’ll be using RO water from start to finish this time instead of my 350ppm tap water that I didn’t know was bad lol I switched to RO...

first off im using pro mix and RO water and in week 5 of flower. so blue lab combo meter took a shit the other night as i was ph-ing straight ro water. it went from 5.5 straight to 7 and stayed locked there, put it in 4.0 solution.... nothing. so i said ok ill just guess a little bit and...

I know you arent supposed to go by the straight ro water for the ph but the water out of the ro system reads about 40 ppm, when I add cal-mag then check the ph it reads around 6. Is this a clue as to what that 40ppm consists of that is getting through my RO filter? @Renfro I already know you...

Hey guys, I recently came across these filters that can directly attach to most taps. It is said to contain Activated Charcoal, Bamboo and some other material. They're used for removing chlorine, heavy metals and lots of other elements from the water that we dont want and as it has to pass...

Can anyone provide a link of a PPM meter that can be used with RO water? Also of anyone can share why regular meters can be used with RO water. Thanks

I wanted to see if these lights could pull of a great grow or if they were crap lights as many assume. See details and photos attached. Stay tuned. 4 GALAXYHYDRO LIGHTS 300w model non-dimmable, simple on/off. Pulling 182 from the wall each. Running typical 18/6 - 12/12 cycles. 9 week Veg. 9...

So my friend is new to the grow game. He purchase a bunch of advanced nutrients, ph perfect n the whole nine (fool). Anyway I advise him that AN is meant to be used reverse osmosis water, which he doesn't have. I forgot to mention that he purchased the bytes online (No returns not free...

Good day to you, RIU Community! ____________________________________________________________ TL;DR My Secret Jardin DR90 (3'x3'x6') has a few factory light leaks that are kind of to be expected.. Should I be worried/take precautions? My RO water also comes out of the filter at 9.0 (which I...

Hellooo RIU Community! TL;DR Bought a homemade "RO" filter (not true RO). Water comes out at 6.6-6.8 pH and 0 ppm (EC unknown). Since filter is very new (have run less than 400 mL of water through it, since I haven't yet started grow), carbon precipitate still comes out in the water from the...

How much magnesium sulfate for 50 gallons of reverse osmosis water?

ZeroWaste® Reverse Osmosis System by Watts Premier I've had this unit for 6 years supplying all my drinking and cooking needs (notice I didn't say growing :) and all I ever replaced was the crummy pre-filter for like 2$...at least a thousand gals and the best part?! ZERO WASTE! Read the tech...

Basically this type of mix doesn't come with any nutrients or fertilizer right? If you use RO water with this type of soil would you use a lower dose of liquid fertilizer every time you water? Or would you use it like the directions say every 1 2 3 etc. weeks? Just starting to think about...

Hi this is my first grow and I'm running into some problems with my plants and need some help diagnosing from some veterans. I have read countless plant symptoms threads and grow pages so I'm not lazy I just have tried everything and can't seem to get things right so I'll explain and hopefully...

Hi all, I have very hard water also, over 600ppm going to 700ppms and it's full of Ca carbonate. During flowering I've had always yellowing issues what seems to be Mg def. I think spraying epsom salts every 3-4 days helps a little, but I'm planning to get a permament solution and get a ro...
