This very mix is widely used by commercial cannabis facilities throughout Colorado.That mix looks nice. whats 25lb cost, how many gallons?
Cost is currently $41 for the bag. At 3 grams per gallon, 25lbs = 11,340 grams/3 = 3780 gallons of plant ready nutrient solution.
To it, you'll need to add 1.5-3 grams per gallon of calcium nitrate. A 50lb bag of that is around $38. I'd also add a gram per gallon of mag sulfate, aka epsom salt.
Doing the math, it adds up to less than a dollar for a 50 gallon reservoir.
For bloom one can add .5 gram per gallon of MKP, aka monopotassium phosphate 0-52-32. It's not even necessary, I get great results without it. A 50lb bag of that ran me $78 and it's looking like it's a lifetime supply, lol
