_Dosing Regime's_

[ZooTycoonMaster]

Ohhh ok. So I mix a tablespoon of it into a cup of water, and dose 2.5 ml. Got it

And I shouldn't dose Plantex at the same time as KH2PO4...say I dose Plantex, how long do I have to wait before I can dose KH2PO4?

I'd suggest going to liquids instead of trying to measure 1/32nd of a tsp

Just mix a 4 week supply in 500ml of water, divide the mls by 4 weeksX 7 days in a week. 500mls / 28 days = ~18mls per day.

Add the macros together and keep the trace plantex seperated in another solution. There's more on it for daily dosing folks under PMDD +PO4.

I'm doing the liquid method here.

Yeah I know (about the 1/32 tsp.) I used 1/4 teaspoon, then tried to estimate half of that, then half of that, then half of that

Dry dosing is easy with 20 Gallons and up. Gets a bit silly with smaller tanks. You can buy those dispensing 1ml bottles for about 1-2$ on line also.
Or the squeeze and fill reservior style for larger volumes(say 5 or more mls).

It is not particularly important nor critical you are terribly accurate, but it's not hard to make a liquid once you have done it once. From there you can dose pretty easy, the issue with accuracy is not critical due to plants having a wide range of nutrients they will grow in and with some simple water changes and frequent dosing, there's hardly any need for a particular level of accuracy.

Think about it like this: The Atkin's diet but for plants.

CO2= the carbs/sugars etc
Nutrients= the vitamins

A plant gets very lean and has little demand for nutrients if there's little CO2........and they lose biomass(Fat.... for us) and do not grow much.

CO2 is far more important to plants like Carbs are for us(if we want to grow and have energy). Our body will use the proteins and use more energy if there is no carbs around. Not easy on the kidney etc.........but it does work.

Same type of thing with plants, the consisency is more important for nutrients and having a bit/even a lot more than the break point limiting level.
You can also have mild(slows growth some) and strong(stunts delevelopment) limiting levels.

There's going to be little difference between say 20ppm vs 30ppm of NO3, but there will be a lot more with 5ppm vs 15-20ppm.

So you have a working range that's fairly large, an easy target to hit given all the errors. And that's the general point with any method.........make that target large and easy to hit.

The range of this target has gotten much larger over the years also.
Thus being easier to hit and manage.

What came into play later was as growth increases, more light is added, many folks got tunnel vision with nutrients and forgot about CO2.

CO2 is where it's all at(if you use it).
I'd spend 90% of my efforts there and maybe 5% on nutrients.

Thanks Tom!

Also have another question - what happens if you accidentally overdose on K2SO4 and KH2PO4?

[plantbrain]

You go straight to Hades and never return

Nothing really.

You do a water change and then things are fine.
Flks often have swapped nutrients and made errors, some rather large, and that's how we know things like such higher levels do not cause issues, they might have for some folks according to them and poor test methods and results that do not support their claims, but for us to be sure, we should see this when we dose a lot everytime, not just a few% based on results who knows what all was going on and no one can say much about.

With the PMDD +PO4 (http://www.barrreport.com/estimative...html#post23098) dosing, is a GH booster absolutely necessary? What would or would not happen if that solution were mixed without GH booster?

Found my answer...

So if I get a couple of those 500ml bottles that you squeeze into the built in measuring chamber, you are saying that I would have one bottle for my KNO3/KH2PO4/K2SO4 and another bottle with the Plantex CSM+B?

The KNO3/KH2PO4/K2SO4 will all stay in suspension in one bottle without locking eachother out? I assume I will have to use a 4:1:1 ratio, respectively.

Sorry if I'm a little late to the parade.

What happens if the tank doesn't get fertilized for 2-3 days while I'm on vacation? Not much?

[Wö£fëñxXx]

Turn the light way down, but leave C02 running with the lights
on a timer, you will be fine.
Do a water change and dose that day or the day before.

If you have a few days/weeks before you leave try it before
you leave as a test.

[ZooTycoonMaster]

I have a T5 HO fixture...should I just remove a bulb, if that's what you mean?

And no, I'm leaving tomorrow

[Wö£fëñxXx]

Raise it up 4 or 5 inches or set a timer to run light and C02
for 3 or 4 hours a day until you return.

I don't think you can pull a bulb on a T5HO fixture and
it work on that circuit.

Next time, wait until the last minute to learn these things,, hehe

[ZooTycoonMaster]

Is there any ill effect(s) from switching from EI dosing to PPS dosing?

[Wö£fëñxXx]

You will lose your right to be in clubEI..

Not that I know of, dosing is dosing, and plants are plants, as long as you
feed the plants.

You'll start posting thread after thread with photos asking "what deficiency is this?!"
