I got my dry fert pack from GLA - (
here) and that has all the micro and macro powders you need in each formula...here is the formula:
You also need 2 1000mL dosing bottles from GLA. You will also need a gram scale- i got mine from amazon. Here is what Rivercats told me when I was learning lol:
The fertilizer package has your nitrates, phosphates, potassium, and the CSM+B is your micro nutrients. **These 4 packages you get are all you need. *Plus 2- 1000ml dosing bottles from them too.
Then mix your macro solution:
In 1 liter bottle: *(which is the 1000ml dosing bottle)
59 grams K2SO4 (Potassium Sulfate)
65 grams KNO3 (Potassium Nitrate)
6 grams KH2PO4 (Mono Potassium Phosphate)
Fill with distilled or RO water and shake well. Let sit overnight.
Next mix your Micro Solution:
In 1 liter bottle: *(1000ml dosing bottle)
80 grams of CSM+B or equivalent trace element mix
Fill with distilled water and shake well. Let sit overnight.
Also add 5ml of Excel to each 250ml of Micro and Macro mix
(20ml Excel to a 1000ml dosing bottle)
Thats it!
