ppm

have a 8x10x8 growroom. Does anyone knows how high to set my flow rate and how long to reach 1200ppms in my room.

Thanks in advance for the help, and thank you to those people who have provided input in some of my other posts. I live in a desert climate. Warm in the summer and cold snowy winters. I have a 4x4 gorilla grow tent and during the summer I was exhausting through a carbon filter (due to...

Hi guys n gals. This is my second attempt, the pictures are from Friday 7/26/19 end of week 3 from the clone shop. My first was medical mass and I proceeded to neut burn .. light burn .. and every other burn to those poor plants. Needless to say it did not turn out great. This time I am fairly...

I've read alot of mixed reviews and advice on where you want your PPM "runoff" prior to chopping. I'm thinking 300-400 should be good is that right in your opinion ? * Note * I'm 14 days out from harvest and have started using straight water ph'd @ 6.2 - I also read plenty about how you want...

So, My Question is water and PPM related Lets say my Tap waters PPM is ~200 and I'm looking for 1000 PPM of Nutes for a feed, Am I looking for a PPM reading of 1200 PPM or am i still Aiming for the 1000??

My new location uses well water instead of city tap. The ppm of the well water is 175. I want to start a single dwc bucket (5gallon), but is the 175 ppm too high? My nutes suggest 300ppm for seedlings. Because my location is very rural, the nearest store for distilled water is some 30...

I was just looking to get a recent thread going about how much you guys like to feed. Super Soilers: How much of what do you amend? Do you have to feed by flowering? How often are you watering a matured final potted plant? Hydro: What does your EC look like is the reservoir? Soil: What kind...

So I'm creating this to reduce my redundancy. Consider this as my reference thread so I don't have to type the same stuff over and over again, I understand it can be cumbersome to search through threads endlessly only to find partial, inconsistent and often plain false information. I was...

I've been using liquid GHE fertliser for years, always had Calcium issues. SO I started mixing my own from salts. Fun. Though I can use some expertise How much calcium is generally adequate for DWC? My plants aren't complaining, yet, 4 weeks into flower, but being optimal can't hurt. Worried...

Hello ya all ,i am a total noob enjoying the journeys ! I have 4 girls in coco-perlite -zeolite (waterfeed ph 5.8)are just fed with 230ppm organic notes (cana) for the second time in their lives . 2xC99 Northern Lights ,back 2xC99 (Cindy,cinderella) I have recently started making bokashi...

im using a rdwc system, My set up has been fine so far, I’m 3 weeks in to veg and I’ve noticed over the past 2 days my ph has started dropping last night it was 5.8 then I’ve got home from work tonight and it’s dropped to 5.7 and my ppms have risen slightly? Sorry if this sounds like a newb...

Hey guys. Growing in coco outdoor, week 4 flower and decided to switch to synthetic hydro nutes instead of my organic nute I use, which has too much nitrogen for my liking in flower. I’m currently watering it at 2.6ec, previous watering was 2.4ec, before that I did 2.1 and 1.6. It’s a big...

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...

Hello All! My two short rider dwc auto flowers have started to flower! They are about 25 days old What should the ppm be about at this stage? I am using general hydro flora, grow, and micro series with sensizyme, rhyzotonic, and cal mag. Thank you!

So I'm currently researching DWC and I was wondering if someone could answer what it means if: PH lowers, ppm rises but water level is stable. and PH stable, ppm rises but water level stable And PH rises, ppm and water level stable

Originally this was a grow w/ a journal. But considering the events about to be explained, it will now be an example. Nutrient burn! If you haven't heard of it get a ppm meter. If you have heard of it and experienced it prepare to cringe! If you have heard of it but have only seen examples of...

Getting lots of conflicting info on this subject or the conversation heads toward math and science i don't understand. Issue: Growers say how many Ppm's of nuut's they add, say( 900-1400 ) so if I add my nuut's to a gallon of water by what the bottle says ( 14ml per gallon ) and I check the...

Sorry, posted by accident. Seems I was watering it vinegar, had no idea all this time. live and learn! lol

Hello all, I have a question about PPM… I have been using the “grow bosses” 75ppm each week and to be honest my plants look thin and tired. None of my plants have grown to it’s full potential; they are nice but small for 7 weeks. The plants grow slowly until about 525ppm is given but by this...

What it do RIU, Anyone have any experience with one of these setups? How easy is it to setup? How good is it? Any other recommendations for an automated system...
