Question on EC and Co2

[Jkooper]

I'll keep this brief.

I read that some hydro growers don't go past 1.2 EC when it comes to nutrients at full bloom. So assuming you are using tap water, do you measure 1.2 EC of nutrients plus the EC of the tap water (example 0.4 EC tap + 1.2 nutrients = 1.6 EC)? Or is it more important to not go over a specified EC overall including your tap water?

I've been thinking of doing a grow in an close room with no windows or vents, basically purely sealed. I've had no issues in a open environment, but would a tent in a closed room give me deficient Co2 issues? The enclosed room will provide a cleaner environment which is why I'm considering.

It really depends on how sealed the room is, how often you go in there.

The other thing to consider is temperature. Will you be using AC, stand-alone in room scrubber to help keep smells down some?

as for EC I barely exceed 1.4EC (including my 0.2 water - 0.2 water 1.2 nutes) and that’s usually only during stretch to sustain the additional veg growth and supply enough N so that the nodes don’t get too stretched out.

on my last grow I barely exceeded 1.0 including tap EC. So 0.2 water and 0.8 nutes.

but I’m in coco and feed multiple times per day.

No AC as the room ambient is 60F. Carbon filter will be used yes.

My tap is 115ppm, not sure about EC since I dont have a meter for that. I should rephrase my EC question and ask if the tap water ppm should be included to the maximum ppm (EC) since the plant is also absorbing whatever is in your tap water,

Personally I have always included it.

what medium are planning on using?

 

[jondamon]

Also have you tested this area for heat with your chosen lighting?

 

[MisterKister]

Save yourself the headache and get an ro filter it will be the best 70 bucks you'll invest into your grow

Water (DWC)

Also have you tested this area for heat with your chosen lighting?

No, but I am using LED's, I'm more afraid of it not being warm enough.

I want to, but I don't have a convenient place for one. I was looking at the Stealth RO150, I think it's only $150. Can you link the $70 one you might use?

I run the stealth 150. It's was about 300 in Canada. Dont get a cheap junk Amazon ro unit. Hydrologic makes good units that won't flood your house.
I just used some sharkbite fittings and spliced it into my cold water going to my laundry sink.

I do have pex piping going to my laundry but no sink. I could install a sink but it maybe more work than I plan on wanting to put in. Hmmmm, I assumed more than just a sharkbite fitting would be involved in a RO setup. It might be a lot to ask but do you have a picture or a link to a similar setup?

115 x 2, divide by 1000. .23 EC

Easy peazy lemon squeezy
I just added a shut off so I can use the sink and it won't pull the water out of the unit backwards

Why not just divide by 500?

Because I said so.

More co2 = less transpiration from the plants which = less uptake of nutrient solution. This is due to the stomata on the leaves closing/restricting due to being adequately enriched with co2.

That being said common sense would say you increase nutrient solution strength as you increase co2 enrichment. Also you'd reduce irrigation frequency. In hydroponics you'd notice your reservoir(s) not depleting as quick.

Don't read the bro science and read real science. This forum has lots of douchebags on it that will tell you bullshit information or give you stupid responses like "Because I said so".

Thanks for the pics, doesn't look as complicated as I though it would. I guess I'll install a sink since I would like one anyway. Is the ppm low or nonexistence? Does it Taste good?

Thanks for the link, I'll read it. I maybe able to leave the door open to the room which would help, just don't want the animals in there. This forum has some toxic folks, but there are diamonds in the rough that have far more experience than I will have anytime soon. Mental illness is a growing problem these days, best to just ignore those types of comments.

I think the reason some people do that is because it's easier to do it in your head that way. But if you're gonna use a calculator it's just an extra step.

Plus one for the “sensitive” side.. but really, my first comment was legit, can’t help some dumb ass needs to make unnecessary comments like usual followed up by tweedle dumb commenting on that original useless information response from me. Welcome to riu, thicker the skin the better.

Set these up right and you won't have to worry about flooding
