Great, thanks I needed that! lol Its good to talk it out, I'm pretty slow picking things up sometimes but if I get a lot of info from different sources some of it eventually sinks in. Pretty soon I'll be as smart as a 6th grader. lol
This morning I was introduced to VPD attached to a scary name VAPOUR PRESSURE DEFICIT ( Canadian version) awe fk it was going to be a casual Sunday, walk the cat, play with my plants you know an easy day but oh no VPD has to walk into my brain and it was going to stay there until I figure it out . Now I've spent a good portion of the day reading the posts & watching the videos about VPD and thought I was catching on then wham fkin Algebra. I had it covered pretty good back in trade school but that was a long time ago and I'm not going through that again. Now after all my learning today I'll still just have to guess what my actual VPD is gees thanks guys there goes my Sunday. lol
If you want I can email ya my spreadsheet. All the calculations and formula is done and named... Just plop in you number and it tells ya.This morning I was introduced to VPD attached to a scary name VAPOUR PRESSURE DEFICIT ( Canadian version) awe fk it was going to be a casual Sunday, walk the cat, play with my plants you know an easy day but oh no VPD has to walk into my brain and it was going to stay there until I figure it out .

No thanks for the offer but I get the gist of it I don't think I need more info, it would just confuse me more.If you want I can email ya my spreadsheet. All the calculations and formula is done and named... Just plop in you number and it tells ya.
No no the spreadsheet just has the calculator. So all you need is to punch in the numbersNo thanks for the offer but I get the gist of it I don't think I need more info, it would just confuse me more.
No, no really I'm good I can't take anymore, I'm full, Anymore at this point and I'll crack. lolNo no the spreadsheet just has the calculator. So all you need is to punch in the numbers
Maybe not as accurate to the exact point of ph but it's dam close and in the vicinity. It's not like you'll read 6.5 with a runoff test and a slurry test will give you 5.5. It will be in range closer to 6.5 than 5.5. When I now do a runoff test I suck all the water out of the pan after watering then I take the test from the last water oozing out of the plant, this way I'm, assured of water that has leached through the soil and didn't just run down the sides of the pot or found a dry channel to go straight through and give a false reading.UPDATE:
the Indian bubble gum plants tested at 7.2 runoff today! The new mix, excluding the perlite is 1/3 promix. Wish I'd listened to @Jimster who recommended not adding the dolomite to the new mix! :/
Everything was flushed and all the numbers recorded today; The plants with the high pH got an additional watering of 6.2 which they'll get for the rest of their run, they'll be done in under 2 weeks. Because they were looking good I kind of let them go but now I'm bringing pH down
- The runoff numbers for the new mix (which is the same as the old mix but without the dolomite) was 6.2 - 6.4 and all were under 500 PPM ~Primo!
A thought on runoff:
You may see a lot of people who claim it's useless or even counterproductive but I disagree. I believe it's a great way to know what's going on in general in your medium. Granted it's not as accurate as a slurry test, but it tells me when I need to do a slurry test and that alone is value in my opinion
Nice and clean with space to grow. I see some guys with the room packed with no room to move, a little extra space makes things much easier to maneuver around when watering or just maintaining your plants. Light gets through to the lower parts of the plants as well.I just have to post this again!

..in >2 weeks this will be my real world!
I almost can't believe it?! Having my Bloom tent laid out like a 5 on a dice has been my dream set-up for a long time
It was so difficult and took so long to get to this point (& no milk crates to move around❤) I'm going to maintain this plant count & size going forward.
That's an hso black dog in the middle of 4 Indian bubblegums
Take it from the first water to come out next time. I forget why but I think it's because That's more of a better picture of the soil conditions than the last of it to come out which could be the water you've just poured inMaybe not as accurate to the exact point of ph but it's dam close and in the vicinity.

Oh man you have no idea I was ready to scrap the extra plants yesterday and just leave it like that lol! (I thought about it believe me) it's taken me about a year-and-a-half to get to this pointNice and clean with space to grow.

I find when my plants are in need of water that the soil pulls away from the pot and water immediately flows through to the tray. After a good watering and the soil is all wet the water that comes through has been in the soil and not just run through water. The first ph test I'll take is very close to the ph of the water I added because of run through but the last test with no run through water is more accurate for me and closer to the slurry test results I've taken.Take it from the first water to come out next time.

I may not have explained that well but I've only had half a cup of coffee so far, but yeah it's a thing
What I do is pour 40 oz of plain 6.5 in my 3-gallon pot and wait a minute or two
Then I pour another 40 oz 6.5 through and almost immediately I'll start getting run off and when most of that is in the tray I'll swap out trays allowing the plant to continue to drain in the new tray, and will test what's in the first tray
Well I mean you can continue doing it that way of course, but if you look into it or maybe somebody else can post in here about this, but I've been taught you need to take the first runoff and for the reason I (hope I mentioned fairly clearly?) aboveI find when my plants are in need of water that the soil pulls away from the pot and water immediately flows through to the tray.

The key here is water slowly!!! If your soil is dry the water runs straight thru water will not take on the ph of the soil . Run off must be cked after the media is completely moist!Well I mean you can continue doing it that way of course, but if you look into it or maybe somebody else can post in here about this, but I've been taught you need to take the first runoff and for the reason I (hope I mentioned fairly clearly?) above
Edit: I won't link to that site because it's a hate site but you can find it and likely other sites on this topic the same way I did if you want to read more on this subject

The first water & the last runoff aren't going to be the same. I've taken first and last and they can be and usually are substantially different
Just a thought on that whole water channeling thing, probably has some truth to it but I personally don't worry about itMaybe not as accurate to the exact point of ph but it's dam close and in the vicinity. It's not like you'll read 6.5 with a runoff test and a slurry test will give you 5.5. It will be in range closer to 6.5 than 5.5.

Exactly! ^ Above I recommended pouring in 40 oz and leave it for a minute or two then pour in another 40 and that's when I draw the water out when it starts to flowThe key here is water slowly!!! If your soil is dry the water runs straight thru water will not take on the ph of the soil . Run off must be cked after the media is completely moist!
In the end this is just another tool that everyone uses a little different !!
My opinion is it’s fine to check the runoff but if ya really want to ck the soil the best you can ? TAKE-THE TIME TO DOTHE SLURRY!
