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 }

Cheers

Hello All, just to bring this to a newer page, but the prices of what Scoop1

got quoted from WESCO 6 years ago. The prices today are maybe Bt. 1-2000

more today's prices get somewhat of an idea of the cost.

With 1 ea. of the chems above, I would be able to make 20-10L. kits of grow.

and need a bag of potassium sulphate to make bloom.

Todays cost for the above salts and the micros cost from my last post comes

out to Bt7070.  +or- Bt.1000  doesn't cover the pot sul cost for bloom.

Buy another box of Fe and you can make 3 more kits before you need to buy

another bag of calcium nitrate and the buy as needed cycle begins.

Hi rice and any one interested, I gravity drip feed my Tomatoes with a 30ltr drum , 4 double truss stems per 20 litre bucket and there are five plastic buckets , each bucket has 4 adjustable drippers, what you need is to have leachate before the sun reaches 80% of its intensity and you need to have 30% leachate at the end of the daylight period, so you adjust your ON time and off time and your adjustable drippers to achieve those parameters, if you don't have leachate before that, you have the OFF time at the end of the daylight period going off too early or you have your ON time coming on too late, or your drippers are no dripping fast enough, so its a balancing act between those three parameters and the environment conditions and plant growth stage, and that is the best way of doing it, turning pumps on and off several times per day is not good nutrient management , consistency is everything in hydroponics and being "consistently clinical" and "clinically consistent" is so very important if you want excellent results , with good quality coir which has excellent drainage properties you cant really over feed them, but its best practice to get yourself comfortable with the system you are using, there are some photos on here of my system if any one wants to have a look .

Cheers

Ps - I set my drippers to be dripping at a fairly good rate and try to have each bucket dripping at the same rate and then I adjust the supply tank valve to give myself[ a little more control as the plants and environmental conditions change

Hello All, Scoop1, not much of anything, waiting for the rainy season

to lower the EC of the water here,. Very high salinity here, the old place

had a good well, the village water was pumped about 250M away.
