Wesco Fertiliser Salts Pricing { this is the quote i got a few months ago, because of the price of the Sodium Molybdate it may be better to use their Micro Mix or ask for a much smaller amount as you only need .2 of a gram to make 20 litres of Concentrated Nutrient Solution }

For PART A

Calcium Nitrate 25kg @ 30tbt/kg = 750tbt

Iron Chelate { Fe EDTA } 1kg @ 370tbt/ kg = 370tbt

For PART B

Monopotassium Phosphate 25kg @ 68tbt/kg = 1700tbt

Potassium Nitrate 25kg @ 48tbt/kg = 1200tbt

Magnesium Sulphate 25kg @ 20tbt/kg = 500tbt

Solubor 1kg @ 300tbt/kg = 300tbt

Zinc Sulphate 1kg @ 50tbt/kg = 50tbt

Manganous Sulphate 1kg @ 50tbt/kg = 50tbt

Copper Sulphate 1kg @ 125tbt/kg = 125tbt

Sodium Molybdate 1kg @ 3000tbt/kg = 3000tbt { very expensive }

Thanks Bina, Rice555 has opened an old Hydroponics Thread and i have re posted my information on that thread, i dont know what to do,posters are asking questions and i dont know what method they what to know about , but i understand that some like to have it all on the one thread, may be they could put a header on their posts so we know which method they are asking about.

Calculating a Target PPM from Fertiliser Salts for a Hydroponic Nutrient

I always like to work with 5 litres of Part A and Part B of Concentrated Nutrient Stock Solution to make 1000 litres or { 50ml of Part A and 50ml of Part B to make 10 litres } of Working Strength Solution [ expressed as a dilution rate of 1 - 200 } lets start with Calcium Nitrate, Remembering that Calcium Nitrate has around 1% of the Nitrogen in the Ammonium form { NH4 } as an impurity, and 14.5% in Nitrate form [ NO3 ] this sometimes is not labeled on the bag but simply states 15.5%N but it is important in the calculations

Calcium Nitrate = 18.8% Ca

14.5% N - NO3 Nitrate Form

1.0% N - NH4 Ammonium Form

Lets say we want 102ppm of calcium in the Working Strength Nutrient Solution

102ppm x 100 = 10,200

10,200 divided by 5 { 5 litres of Concentrated Stock Solution } = 2,040

2,040 divided 18.8 { Percentage of Calcium in Calcium Nitrate } = 108.5 grams/litre

So you would use, 108.5 grams of Calcium Nitrate per litre of Water to make the Concentrated Nutrient Stock SolutIon which will give 102 ppm of Calcium in the 1000 litres of Working Strength Solution if you use a 1-200 dilution rate.

108.5 x 5 litres = 542.5 grams to make 5 litres of concentrate

108.5 x 10 litres = 1,085 grams to make 10 litres of concentrate and so on

Hope this is not too confusing and i will let someone else work out the what the two Nitrates are adding to the mix { no prizes for getting it right sorry }, i hate typing, lol

Cheers

Ok its raining and i'm bored so i will do it, so we have got our target ppm of Calcium now we have to work out how much Nitrogen in both forms are being added to the nutrient from the Calcium Nitrate

NO3 = 14.5%

move the decimal point one place to the right, ie 145.0

145.0 x 108.5 { grams/litre Calcium Nitrate } = 15,732.5

15,732.5 x 5 { 5 litres of Concentrated Nutrient Stock Solution } = 78,662.5

78,662.5 divided by 1000 { litres of Working Strength Nutrient Solution } = 78.6625

So 108.5 grams/litre of Calcium Nitrate adds 78.6625ppm of Nitrogen in Nitrate { NO4 } form

Now lets do the Ammonium Nitrate form { NH4 }

NH4 = 1.0%

move the decimal point one place to the right, ie 10.0

10.0 x 108.5 { grams/litre Calcium Nitrate } = 1,085

1,085 x 5 { 5 litres of Concentrated Nutrient Stock Solution } = 5,425

5,425 divided by 1000 { litres of Working Strength Nutrient Solution } = 5.425

So 108.5 grams/litre of Calcium Nitrate adds 5.425ppm of Nitrogen in the Ammonium form { NH4 }

As you can see from the calculations, 108.5 grams of Calcium Nitrate supplies

102ppm of Calcium

78.6625ppm of Nitrogen { NO3 ]

5.425ppm of Nitrogen { NH4 ]

Totals

102ppm Calcium

84.0875ppm Nitrogen of which

6.45% of the Total Nitrogen is in the Ammonium Form { NH4 }

The A micro is: Fe 7%.

rice555

Hi Rice , thank you for that , what is the dilution rate they say to use, i want to put the ruler over it so if any one wants to make there own nutrient its known what the ppm of the individual micros is in the nutrient solution, and do you know what their Hobby Set consists of in regards to the macros, Mgo??????

Thanks

This thread is getting a bit disjointed now

Some are talking aquaponics, and some are talking hydronics in the same thread. I can see this getting really messy, lol !!!!

Perhaps its time a decision was made whether or not we get sub forums for each?

great idea, waiting waiting!!

A bit late and hurry, but I'm interested to a subforum too. I run an hydroponic bank to grow rocket for my restaurant ;-)

Thats great anguid, tell us a little about your system, do you make your own nutrients, are you using an open or closed system

He May be growing Indeterminate tomatoes, commercially thats how it is done and you have to get on a ladder to harvest them, it is an efficient way if it is run well, but the longer they are growing the closer you are to disease problems, to do it that way you have to be very clinical about your growing practices

Hydroponics

There are many ways of growing fresh produce hydroponically, but i think to start with it is best to try and keep it simple for those who have had little or no experience and build up from there, i know this may make boring reading for the more advanced growers but i think it is necessary, as regards to what is needed, i think most people will have something lying around the house or farm that will do just nicely, hydroponics can be as simple or as scientific as you want to make it, its not always lots of pipes and pumps , the most simple and idiot proof way is a simple plant pot or bucket { Plastic } with drainage holes the pot can be filled with an inert substance such as coir { Coco Peat } although coir is not totally inert it is used widely in commercial hydroponic production and normally has an EC { Nutrient Strength }of less than EC .3 and this is fine for hydroponics , after you have potted the plant its time to feed it some nutrients and any excess will just run out of the bottom of the pot, so you really cant drown your plant, that is the simplest way, very very basic which is called "Run To Waste" or an "Open System". As for the nutrients! this is where the decision making begins , if you buy pre-made then you have to totally rely on a manufacturer for your nutrient needs, which can get expensive if using a lot and also you dont know exactly what is in the nutrients and at what amounts , that are in the bottles, and there have been manufacturers sued because what was written on the bottle was not what was in the bottle, and if you have to buy nutrients, in Australia it can cost up to $180 for 4ltrs of Part A and Part B ,and its only worth about $5 to make yourself , i personally think that anyone wanting to grow hydroponically should learn how to make there own and then they are in total control, which is what hydroponics is about, total control over the growing environment. For people just starting out with, lets say, 6 pots with Pak Choy it probably be better to buy pre made to start with and see how you go , making your own is not that hard, you just need to learn a few calculations and have a good set of digital kitchen scales

Hope this helps a someone

I only inquired about a subforum on Hydroponics, considering that there is already a pinned section on aquaculture/aquaponics i think hydroponics should stand alone because of the vast difference in the two, this is only my opinion of course,

Scoop

The only thing about pinned threads is that they get lost in the mists of time, as it were

Like your title states, perhaps a sub forum on each of the 3....Hydroponics, Aquaponics and Aquaculture.

This might generate a bit more interest than at present.

In fact i am very suprised there isnt a place for the aquarium folk to post/gather

Isnt this a popular enough pastime in Thailand, i wonder?

Penkoprod

Totally agree

Hi Loong, i dont go much on the fancy varieties, to me they look great as a decoration but a little bitter, i much prefer to eat head lettuce and they do very well in a single pot with coir and a good nutrient, too easy, but as with everything in hydroponics the rain has to be stopped from getting to the plants which is not that much of a problem if you only have few plants

Cheers

Scoop

anyone got any drawings on any equipment they have made, just buy sourcing pipes etc from the local hardware store? ie the set up they have designed to stand the plants in.......

also, where do you buy the food from? what is good for growing vegetables, and how much does it cost?

Hi UKJASE, are you talking about Hydroponics or Aquaponics, i may be able to help you with information on Hydroponics, { making your own balanced nutrients for the crop you wish to grow, what to use and how to use it }, its best for any novice to start off very simple and learn that way, its important that you get a good result first time, but Aquaponics is not my field of expertise someone else will be able to help you with that i am sure. If it is Hydroponics you are interested in, tell me what you have grown before and how did you grow it, if you have never done it before i will explain some simple ways to get started in a very small way, the only problem is the nutrients and if you wish to make your own.

Cheers

Scoop

Hi Loong, are you growing Fancy lettuce or Head lettuce, may be you could get a variety that is suitable for the hot climate, they certainly will bolt if they are not grown quickly. Tip burn is not usually a serious problem when growing in soil but Fancy lettuce grown in hydroponics in hot conditions will suffer tip burn if the nutrient is not formulated to combat this

i am interested in hydroponics too..... i would like to get some tips and information from others on here
