I received my set of bottles to make my own liquid stocks from dry ferts, and to make it easier for me to keep up with dosing. I'm having a little trouble with my math tonight, so I'm looking for some help. Here's what I have so far.
16 oz bottle. Approx 470 ml.
Each pump out of the bottle is .8 ml. I get approximately 590 pumps out of each bottle.
What I am thinking for convenience is 10 pumps per bottle, 3 times a week. That comes out to 8 ml per bottle.
According to EI dosing, each week I should have:
2 1/4 tsp KNO3
9/16 tsp KH2PO4
9/16 tsp CSM+B
For KNO3, it's 3/4 tsp for each dose. So 3/4 tsp per 8ml of water.
470ml / 8ml = approx 60 doses. That's 60 (3/4 tsp) doses.
Does that mean I would put 45 tsp of KNO3 in a bottle of 470 ml?
If I am off, which I think I am, please shed some light on the subject. My brain hurts tonight trying to figure this out!
