If they would’ve told me this is what chemistry was used for in high
school, i would have tried a little harder?
+mhpgardener As always, fantastic video, very informative. Questions: Many
fertilizer feeding schedules are written out in teaspoons. I’d like to see
how their scheduled PPMs compare to your formula here. I don’t know how to
convert a teaspoon of a given fertilizer into grams. I know a teaspoon is
5ml, but that’s not grams. The MSDS has a relative density of 2.2 (for my
fertilizer), does this mean 2.2g / ml of fertilizer??
hmm I can’t seem ti find any directions for the mix ratio at all on ether
website?
Would this hydroponic fertilizer work for all vegetables in the garden and
where would you recommend me to get the ratio ( example 10-10-10 , 13-13-13
ect..) from to be able to get as close to the right mixtures as I can??
You are the best teacher i have ever seen . Thanks for your amazing
detailed video and information.?
Great job! thanks for the help!?
Hi Bobby , I would like to ask you what you think about using Pro Mix
with Hobby Formula 10-8-22 and a 1/4 ts. of Episom Salts ? Thxs?
How far apart do you put your Dutch buckets for tomato plants thanks?
have anyone used an “organic” nutrient solution successfully with the
kratky method ? what have you used and what are other “organic”
alternatives that will yield relatively close to MasterBlend or Chem-Gro ??
here is a 2 year old comment so if you have found out, sorry. did you know
that adding baking soda lowers PH? i learned this when i had some
aquariums. ill have to try to remember what i used to raise PH.?
thanks for the great info. I’m pretty sure Cleveland from family guy stole
your accent. Just the way you guys say “Terrible”. Im in Aus and we got
some funny accents down here too 🙂 I’m sure you’d be laughing at mine.
Great videos. Thanks so much.?
Hey there, I bought the master blend and the epsom salt and calcium nitrate
and mixed them according to your portions. Everything mixed up well but it
remained clear, not green as I have seen in some of your videos. Any clue
as to what did or did not happen? Perhaps it needs to dissolve over night??
hi mhp, wat is the nutrient solution for pepper plants in every 5
gallons… pls answer me plss,,,?
Can you use this formula on raised beds? ?
Within the next week, most likely this weekend, I am building a 10 bucket
system with the specifications of your vid from Oct. 8, 2012. I have
watched this video a few times and am not sure on one issue. If I want to
plant 5 buckets tomatoes, 3 buckets peppers and 2 buckets cucumbers will I
be able to use the 19.5/18/38 solution mixture in the reservoir for all
plants? I don’t want to grow only tomatoes, but I can’t set up 3 different
complete systems.
Thanks for all the great videos!
K.H.?
Did you know Master blend is using your youtube video on their web site??
You’re on Masterblend’s website! That’s really cool!?
Do you know if this will work in an aquaponic setup? Will it kill the fish??
A lot has been said that PH levels is also important. It seems that the
nutrients do affect the PH levels significantly therefore after the water
PH is at the right level then adding the nutrients throws it off often
times PH goes way down. And the task now it to increase the PH to hit the
proper level. What is the best practice? Can anyone (Bobby?) let me know
if it is good to test and work on the target PH level AFTER mixing
nutrients and NOT BEFORE??
Thanks so helpful?
what do you recommend for foliar fertilizer in the outdoor garden? miracle
grow for tomatoes for a general rule????
I taught fertilizer materials calculation at a State College. Corey P reply
is correct in the fact The combined Master Blend and Calcium Nitrate is
actually 9.75 – 9 – 19. See his post below for a explanation. You forgot
to divide by 2 since you had twice as much weight.
By using a EC meter to measure Part Per Million you can better adjust your
Fertilizer to the Variety of plant you are growing. Tomatoes are heavy
feeders and 1200 PPM of fertilizer is a about right for growing Tomatoes.
Lettuce grows nice in 400 to 500 PPM. Too much or too little fertilizer
will stunt growth. Remember to start with a Base line of PPM before adding
the need PPM of Fertilizer.
The way I deal with the objection below about Magnesium (Episom Salts) not
mixing in, to use Chelated Magnesium Nitrate 7 – 0 – 0 which is a Liquid. I
also use a small submersible fountain pump to keep the fertilizer agitated.

Only hydropoinc gardener I have seen that actually takes the time to
explain his experiences… very well done mhpgardener… keep up the good
work?
Can’t tell you how many times I have referred to this video. Very
helpful. Thanks so much.?
Hey Mhpgardener, the math on this isn’t quite right, my friend. You’re
adding ratios, not actual whole numbers. So, when mixing a fertilizer with
4% Nitrogen, and a fertilizer with 15.5% Nitrogen, you don’t get 19.5%. You
actually get 9.75% (assuming you have the same size bags of both parts).
You get all the denominators to match then you add the parts and divide by
the number of parts. So, 4+15.5=19.5 and 19.5/2= 9.75%. Same goes with the
other two parts.
If the Masterblend and the Calcium Nitrate are both the same sized bags
before you mix them, the actual N-P-K is 9.75-9-19. I’m surprised no one
else has said anything on this yet. Love your videos though.?
