question

sorry my camera is old and crappy. i am growning hydro and have no idea what my ppm is or has been for the past month since i got the plants. i will get a ppm meter. what should the ppm be at? also wondering what EC is and why that is important to know
 
well hell's bells man...that's a mighty fine forest you have for yourself there.
seems you don't need to know about any ol stinky ppm gibberish to me..

very nice indeed.
 
not at all, no...just keep an eye on the tall lanky one and your gold i bet.

no reason not to know to use and have a test kit around though...for insurance and all

fer sure i think ill go get a ppm meter but are you talking about that last pic cuz i has LSTd it yester day heres a new picpics 053.jpg
its was like a ft taller that the others do you think that will help it fill out a little more or something?
 
no...i am always suspicious of tall plants...the males need to be the tallest so gravity does it's thing with their pollen.
just paranoia really...

i bought them as clones from a collective they are all females but that one was pretty talk so i did the LST thing

thanks for the link very complicated to understand i may be to stoned to get it. in gen did it say that ppm and ec were basically measured the same? so if i get a ppm meter will that suffice or no?
i think i like being an idiot and not paying attention to the ec or ppm lol. it seems to work ok for me :P
 
im assuming that i am probably one of the only ppl not paying attention to their ppm or ec and no one can answer my question? really?

Don't fret about EC just yet. I never did, in fact up to a certain point, I had never heard of it even being applied to growing.

I only worried about reservoir temp, ph, and ppm. And I did quite well.

If the post you were linked is too complicated, then I would suggest researching testing pens. Check the hydro store, and see if they have one that can handle multiple "variables".

A multi pen is most likely the best route, IMO.

For example......

Muti-Pen: EC, TDS, and PPM
 
fer sure its wasn't to confusing im just not sure if i was correct in assuming that ec was just basically a different way to measure ppm. if it is then wouldn't you only need a ppm meter and not both ppm and ec? heres the link to that thread https://www.rollitup.org/newbie-central/953-talk-about-ec.html#post4801


For convenience, EC measurements often are converted to TDS units (ppm) by the meter.

The meter cannot directly measure TDS as described above, and instead uses a linear conversion factor to calculate it. Everyone’s nutrient mix is different, so no factor will be exact. The meter uses an approximate conversion factor, because the exact composition of the mix is not known. Conversion factors range from .50 to .72, *depending on the meter manufacturer, which do a good job of approximating a TDS calculation from the meter’s measurement of EC.

* All ppm pens actually measure the value based on EC and then convert the EC value to display the ppm value, having different conversion factors between differing manufacturers is why we have this problem communicating nutrient measurments between one another.

Basically yes. EXACTLY....no.

Get your self a good pen that does the work for you. It'll cost a bit, but cheaper than getting a pen for this, and a pen for that.......and if you don't know the difference between the measurements and how to convert or calculate....these values are useless to you.

I used a mutli pen, and never bothered with all the ins and outs and differences between the measurements.

One that calculated nutrient strength (tds/ppm/ec), and one for ph. Temps of the reservoir were measured with a simple floating thermometer.
