Does anyone store their per gallon nute doses in centrifuge tubes?

canabineer gave spot on infos here, its not a good idea to mix A and B part fertilizers in high concentrations/directly.

if you really think you need to make it, why not dilute your stock solution?
for some fertilizer a 10% stock solution would be ok, max 17.5% is allowed according to some maufactorer.
1% is EC 1.52 , 3% would be a EC of 4.19 (its not linear!), so maybe a EC of 10 is ok for a stock solution idk.
dilute your stock soultion to a level working for you.

getting there. this is great! shaking the cobwebs from what I remember about chemistry. cool, not only will my immediate issue be resolved but I'll make more informed purchasing decisions in the future....

Ok, I made a list of products, including a link to the product label; alphabetically captured product ingredients and what they're derived from; and made columns for solubility notes and pH notes (so far, most notes come straight from the label).
  • Below is a screen shot of part of the draft spreadsheet (not all product data's entered yet).
    • to keep ingredients alphabetized, so I can quickly see what's potentially duplicative, I'm blacking out cells that don't have a particular ingredient.
Next, within the supplements I might be able to combine, I'm going to work through the chemistry a little bit to assess basic things that may negatively affect solubility (e.g., ionic strength (+/-), repetitive ingredients (saturation/also ionic strength), and combinations known to form precipitates).
  • I'll post what I come up with.
Along the way, I may be able to identify products I can discontinue and/or replace. I'm still annoyed that I started with Mills (a mostly organic system that doesn't even require adding cal-mag...) and it was discontinued at the store I use for most of my purchases. Mills is a simple 2-part fertilizer, 6 bottles tops if you buy everything, including their mono-silicic acid product, Vitalize.

So, I guess these are my "before following instructions" pics. Learning curve, coming to you live.

Green Gelato, Crop Kings. Phasing out the purple pneno from Grower's Choice. [Not all seeds/strains came from seed banks.]

Hmm, any thoughts on some sort of automation?

Raspberry pi + relay + PSU + peristaltic pump?
Pi - $40
Relay for 8 pumps - $12
Dual output meanwell powersupply(PSU) for Pi(5v) and Pumps(12v) - $20
Peristaltic Pumps - $12ea x 8?

I currently run Mycodo software on my pi and monitor my PH, EC and temps of my RDWC reservoir and currently just have 2 peristaltic pumps hooked up but plan on expanding between my next grow to 7 pump. Currently just have PH Up and PH Down so that I could monitor and adjust while out of town. Sensors will crush the value of this so if you don't have the money, don't look at that lol. I probably paid $450 for my 3 sensors and boards to connect those but they were mostly plug and play vs generic Chinese ones that have a shorter life and need some troubleshooting.

But anyways - For the pumps, I can send how many ml of up and down I want pumped into my system and can do it from my phone. I'm sure there's a way to trigger a program to pump "flower" "veg" or "seed" programs as well. It's pretty open source but even just entering in the ML of the solution you want is easier than tipping, pulling, looking, pouring, cleaning?

Create like a soda station with shot glasses under each tap and punch in the mls to disperse and dump into your reservoir.

Just to follow up, there is a "function" option where you could build in some sort of standard output, lets say for like 10gallons, input all the MLs you want each pump to output for a standard 10 gallon and hit the "execute all options". save this function and you'll be able to run the exact same function each time you plan to water with 10 gallons... (Again, I only have 2 pumps hooked up so I can't really show further than that)

Rockwool provides abundant silica, no need for any more Si.

Thanks. I like the idea of automated irrigation. I've tried it. Multiple pumps in a ~6x6 with plants on floor and shelves. No sensors. But that's awesome, I really like what you're doing.

When I get to a point where I'm running a fixed number of plants (i.e., I don't have to add/subtract lines every time) and can simultaneously differentiate programmed feeding schedules in perpetual bloom (e.g., GH's 1-8), I'd absolutely automate it. Perhaps, once I'm more familiar with my strains and getting consistent yields, I will revisit irrigation. I'm sure there are ways to plug an end you're not currently using but I just remember there were a lot of over/under-watering issues to troubleshoot and I didn't have time to mess with it then.

Ah, I was just trying to suggest an alternative to your original question of "pre preparing nutes in capsules". Not really full fledged automation of your setup.

No need to prepare the capsules, if you don't really have to do anything when you need them.

Ex.
Put a tube and pump in each of your nutrient A, B, C, D, E and F. Put a shot glass in front of each nutrient with the tube in it. On a table or wherever you store your nutes.

You say you have a set amount you prepare for 10 gallon feedings. Set a function in the program to dispense 20ml of A, 10ml of B, 5ml of C ect. into each shot glass. Save the function and call it "Bloom". Now when you want to make a 10 gallon batch of bloom watering's, you hit your bloom function(1 button), it spits out the amount you need for 10 gallons of water. You no longer need to open and measure each bottle. Just pick up each shot glass(or cup, whatever) and dump into your 10 gallons.
