What is the Nitrogen break down on the label?

NPK of Base A and B is 4-0-1 and 1-4-2, respectively, from Nitrate Nitrogen.

How do I know how much to use in my tower garden?

We used 400 ml each if tub is full (20 gallon) to start. Then 200 ml once a week and that worked for us. If your plants aren’t producing they may need more nutrients.

Is this post sold as 2 32 oz containers of base a and base b? or two 16 oz containers of base a and base b?

It is 2 bottles each contains .946 liters or 32 ozs

Does this nutrient line work well in soil?

I have been using these along with Golden Tree, SuperThrive, Heavy Boost & an enzyme blend. I use this combination every other watering. The alternate watering I use the Fox Farm nutrients. Last crop was excellent. This crop may be even better! Will most likely continue using these 2 nutrient sustems.
