[Dude Man]

I am trying to come up with a feed schedule for High Pressure Aeroponic system.

Okay first I need a Mother formula for a ebb and flow bucket system...


I looked up the the formula for Hydrodynamics Int.
Mother Part A and Mother Part B. i ran them through the pre-mix caculator and got,
N-P-K-Mg
137-20-114-34

Mother Part A 15 mL/Gal
Mother Part B 15 mL/Gal

So I ran some numbers with PBP and got
N-P-K-Mg
132-31-117-41

PBP Grow 8 mL/Gal
PBP Bloom 2 mL/Gal
PBP Soil 0 mL/Gal
Cal-Mag 7 mL/Gal
Liquid Karma 10 mL/Gal
Sweet Berry 0 mL/Gal
Aqua Shield 15 mL/Gal


I wish I knew what kind of N PBP has in it the label just says water soluble??

now on to the veg for HP- Aero

From reading podracers thread i can tell i need to watch out for some things,like


Nutrient balances necessary to avoid lock out or nutrient burn is:

Ca:Mg 3:1
NO3:NH4 9:1
ph is 5.4-5.8

PetFlora journal has some general ppm limits
200-400ppm during veg; 600- 800 bloom. NO MORE!

with that in mind, I go to the caculator!

Early Veg
N-P-K-Mg
108-76-187-59 with a ppm of 575

PBP Grow 0
PBP Bloom 0
PBP Soil 14 mL/Gal
Cal-Mag 10 mL/Gal
Liquid Karma 10 mL/Gal
Sweet Berry 0
Aqua Shield 10 mL/Gal

so I want to cut that in half to get a ppm around 200-400ppm.

so,
N-P-K-Mg
54-38-94-29

PBP Grow 0
PBP Bloom 0
PBP Soil 7 mL/Gal
Cal-Mag 5 mL/Gal
Liquid Karma 5 mL/Gal
Sweet Berry 0
Aqua Shield 5 mL/Gal

now ASS-uming all the N in botanicare products unless listed as something elso is a Nitrate NO3.

This gives a NO3/NH4 = 20/1
and
Ca/Mg = 2/1

now would somethig like this work or
does it need to be closer?

[Dude Man]

any thoughts or critics,

just throw them out their,

I am new at this premix-caculator stuff
and i may of miss read something so just put it out their!!!

one question, for ebb-flow bucket with hydroton should do adj mother formula for the medium?

I have meters and will adj to plant needs of course but want to get the starting mix close to right.
