What are you planning on using your injector with?

The gardens I have seen with injectors are on the Grow More program and switch to organics for flowering...during veg they make stock solutions and use a proportioning mixer to feed everything. I was warned by these people that the products I use (Organic Gem, Therm X70, molasses) will not do well when using a mixer.

Are you going to use the doser for pH control as it comes out of the tank?

Do you use Nitric acid for early season pH control then switch to phosphoric during fall?

therm x70 and sugars wrok great qith my dosers i never have used organic gem ... anything you plan to use thats thick u can use your therm x70 and mix a little before thin with water and use a 200 mesh screen bag..... the only thing i have used that did not work great was a chunkcky thick liquid fish product as for ph i just use normal ph down from mad farmer or ph down from advanced which is a little stronger

planty: Last year I used dry pH up and down from GH... their 16 pound container was the best deal around. I knew no better. I can see the logic behind the nitric during veg and phosphoric during flower. Where do you source your acids?

My hope is to be able to monitor solution pH on the way out of the doser and adjust my 10x concentrate accordingly to make changes.

onetime: Thanks for the info. What are your thoughts about planty's concerns that certain products will cause problems going thru the system?

Rootwise: Sorry to hear about your flu. I got sick last year during harvest. It was the first time in more than ten years that I was sick for more than 12 hours. Blew my mind... I was sick for like 2.5 weeks. Perfect timing.

wotamess: Thanks for stopping by. The smart beds are a bot of a PITA. They need a frame. I have two more that will be put into service at the new project... If time allows, I will do it right over there. Here, we just did it with stakes made from 2x4's and its a bit sloppy.

if u only have one doser the ph becomes tricky cause you will have to add the acid to your nutrient consentrate and i have seen some chemical reactions occur before when i tried this.... cant recalll exaclty what but i bought a second doser fast and never turned back... some times i use 3-6 of them indoors to allow for a full line of products and ph control.....

you will use the second doser for ph up or ph down only...... if you look into large scale coommercial fertigation this is how they do it ... they will use one doser per one part of nutri mix... so lets say house and garden coco to make it easy you would have a coco a doser and coco b doser and a boost doser along with a ph doser this system will allow for total control with no need to change lines and mix ph into concentrate which i have done with out problems most the time but a few times it was no good

So I just adjust the pH doser's ratio till the pH meter gives me the right reading...

you will want to make sure the ph doser is the 180694 model i think thats the numbers ... just make sure it does .5%-2% then you purchase your PH that you want to use and put the doser in and start low and fine tune it..... if you are using a super concentrat you mite have to mix it with water as a .5% mite be too much... i would reccommend using GH or Mad Farmer i like MF its the same stuff no dyes.... once you figure it out and dial it in takes a few days maybe a week you will be dancing with joy telling all your bros what there missing... you seem like the do it yourself type but if you need some help man i am in the 530 most of the time.. and would love to help out.... i have been currently building doser type systems for friends and latly been doing a few Collective Warehouses.

Nice.
I am a DIY guy, but i like to work with other capable people. The first time doing something new, I will always defer to a more experienced person. I let them have at it and suck up as much knowledge as possible. There are also occasions when I am the first to learn something, pass on my understanding to the right person, whose knowledge eventually surpasses mine, then becomes my go-to for that thing.

I am one of those people who would rather be adept at many things then master of one. I welcome your offer for help. I am not a control freak... I like to delegate and appreciate people who can execute. I surround myself with such individuals.

Only 21 posts to go. Here's a trick... pick 10 threads that appeal to you and post "subscribed" to them. You're halfway there.

What's up bro I do not control pH using Nitric or Phos acids..It just works out to 6.4 when I'm done mixing my tank up...they do not comply with the standards I aim to employ in my garden. The grower who showed me about the fertigation , foundation 101 , atv sprayer hooked to 1/2 mainline with 1/4 to tornado misters on stakes is the cat who does the Nitric during the summer and Phos during the fall , grow more 30-10-10 and 20/20/20 during the spring and summer and metanaturals / guanos in the fall mixed directly in to the tank...

Onetime64 is pointing you in the right direction on using at least 2 injectors. The pH control in the set up I saw was directly from the nitric or phos acid HDPE jug with the hose from the doser in it set to the right ratio at the doser instead of diluting...The grow more fertilizers were diluted in to concentrate form. This guys sap levels were pretty much on point in every reading..FWIW.

My intention this year has been to use the nutes themselves to create a solution buffered to the proper pH... if I understand you correctly when you say "It just works out to 6.4 when I'm done mixing my tank up" you are going for the same thing...

What about pH adjustment on your foliar sprays?

I bring the pH up with Potassium Silicate....

The only things I use are fish hydrosylate , cold pressed kelp , molasses , potassium silicate , yucca extract ... In the tea brewer it is activated vermicompost (do this by getting a nice big shallow tupperware..one that could hold a cookie sheet..using baby oat meal ground in coffee grinder I take a big handful and mix it in to 1 gallon pot of vermicompost then spread this out in to the tupperwares in to thin layers and put them on a heat mat @ 80F and wipe the lid every other day so there isn't too much moisture..) fish hydrosylate , cold pressed kelp , yucca

In my quest to balance pH in my nute mixture, I have been testing and marking the effect of each product on pH... not very deep into it yet, but I noticed that potassium silicate is a very efficient UP.

I've also noticed that Botanicare's Silica blast will raise ph, I've used it for just that effect when needed.

Your grow looks amazing Nomaad, much respect bro.
