Grow Mediums A-Train needs info on the coco for future run... help a brother out.
- Thread starter A-Train
- Start date
I wish I had a ppm meter. Lol..... I want to know as well . I just want to use the best source that will allow the advanced nutrients to do thir thing the easiest
I'll tell ya what... I'll take some samples to work and do the ppm testing there.
We have an automated paint process and the wash portion is very regulated they have all the high end testing gear.
I'll do the ph. Testing this weekend and the ppm test Sunday night

Hey Fellas,
I just put together my first simple mix of coco coir. I cut it with 30% perlite. Now sitting at 7% flat.
What type of additional prep do I need to do with the coco mix I have made so far?
I have used OF so far on my first real grow. (fear the nutes)
Amazon is bringing me a couple of big bags of OF tomorrow. I was going to mix it with the coco coir to help each other.
I LOVE AMAZON!!!!

I have not. I am asking if it would be a bad idea. The intent is to buffer the nutes in OF.
I think the bottom line with pH Perfect is that as long as you start with very low ppm/EC water and minimize adding salts/ionic additives, such as Ca/Mg, your nutrient solution will be "pH Perfect" or perfect enough. This refers to optimal nutrient bioavailability of all the individual constituent high-end chelates, not the pH of the mixed nutrient solution (which doesn't mean or matter much, if you start with near zero ppm water).>> BII ---that's the kinda data that matta! All of you are helping me get a better picture of how all this is working, and I appreciate it, truly--
... I tell you what, I'm getting a major hardware boner with this Autopot/Airdome/coco set-up
...I think it's a done deal next chance I can get to grow ID's
If you don't have low ppm/EC water and/or must add salt/ionic additives, it will not be 'perfect,' but from what I've seen here on AFN and with my own few meager grows, even starting with hard water. pHing it down to 5.8 and then mixing in the nutes, including Ca/Mg (CaliMagic during veg, the GO non-N one in bloom), silica (AN Rhino Skin), humic/fulvic acid (AN Ancient Earth), Drip Clean, etc., the stuff still works very well, presumably better than any other base nutes.
Waira: Thank you for the Rep points. You will likely love Airpots/Airdomes. I'm about 35 days into a grow using a standard 3.9 gallon 4-pot system set up as they recommend (50/50 coco and perlite, hydroton/clay balls on the bottom). They are definitely a step-up from Airpots in terms of plant growth. Airpots/Airdomes combine many of the key advantages of coco coir and hard-core hydroponics (e.g., constant aeration), and does this fairly cheaply (just a 1-time purchase) and without electrical power, timers or pumps (other than a simple quiet air pump).
Eventually, if Airpots/Airdomes prove robust enough (with a number of AN members seemingly starting to use them), you may even consider recommending them for first-time grower. Using them is much simpler and zero stress even compared to manual/drain-to-waste feeding -- all you have to do is keep the reservoir filled.

With RO water, when should I start adding Calmag?
I personally would not mix the two.
Day 1 if I'm not mistaken. RO water should have 0 PPM.
This is the first I've ever heard of doing this.. Does CaliMagic have a higher N value? I generally don't add CalMag to my feeds until flower since I use bubbled tap water. I'm very happy using General Organics in flower due to it being 0-0-0.
On a side note, when do you turn your air pump on? I was thinking day 20ish?

correct, RO is 7
