Grow Mediums A-Train needs info on the coco for future run... help a brother out.

[Wile e Peyote]

I just use tap water it's soft to very soft it doesn't show up on my blue lab truncheon I measured it with an old tds metre and it was 50 my problem was it took my ph to low it was ok when I adjusted it back to 5.8 oh and I used coco specific nutes even big bud coco still needed calmag

 

[A-Train]

I don't have an ec meter. I used to ph my water down to 6.0 in the pro mix so I have a ph pen and plenty of ph down I'll probably go that route when watering my coco plants and when I fill the res. Just ph to 5.8 then feed

 

[A-Train]

I I fully intend on using the 3 part grow micro bloom and adding cal mag I have too much left to toss and order a coco product. Folks grew cannabis in coco long before the AN coco line it'll be fine I'm sure

Here's what we'll do I'm going to ph my tap to 5.8 each time and see how it goes.

@MeefChief is going balls out and just mix and water. I'll watch what happens with his lol

...sounds solid my friend-... as long as the coco's thirst for Ca, and to a lesser degree, Mg are slaked, adding a little Ca-Mg should be fine to see that through!... I'd still get a basic TDS meter though, a very handy tool... In the Autopots, this isn't applicable, but from what I'm reading about soilless media, occasional looks at your input ppm and run-off ppm can help keep an eye on potential salt build-ups or other feed conc. issues,...

 

[A-Train]

You're yhe man Waira thanks for the input

So you have now made me check my ph for my AN coco nutes lol.so after mixing my nutes and cal/mag my ph is 7.0.but my runoff is ph 6.0 i checked this 4 times and the ph of the runoff is exaclty the same everytime.does this mean it buffers it after entering the medium.now i am going to get the misses to hide my ph pen and go back to not worrying about it hahahahahaha

 

[A-Train]

In soil I would never worry with it. You'll be fine

FWIW I use tap water. pH is 8.2 or higher, ppm from 150 to 170. My large tote dwc holds 20 gallons, I replenish in 5 gal increments. The last res change was two weeks ago when I changed to a bloom diet. It is a bit of an experiment but I don't plan on changing the res again until after harvest when I clean up. If AN buffering runs out, or expires, I'm sure I'll notice before the rest of you. Keep an eye out for me sitting in the corner crying if I fail.

@Fantasy Island I found the coco grow do you have to rinse or anything or just mix with water and place in pots. I'll be going 50/50 perlite mix

Hey A-Train,
Why 50/50?
I was going to do 70/30 coco to perlite.
Is 50/50 the manufacturers recommended mix?
Thanks,
just on page 5 now..
Lots more to read to catch up.

50/50 is the manufacturers recommendation, but Hans runs 70/30 without issue.
