There are some headed in that direction, to turn the VC into a stand alone fertilizer. But, to say the least, it's not a fast process even with a well established worm bin(s). With a brand new bin like what you are doing, figure on a year at least.Are you only feeding your plants your VC or are you adding amendments to your pots also
This ^^ is pretty much a plain and simple fact. As essential as VC is you are still going to need to amend your soil.VC is not enough to get plants through with a water only garden. amended soils are a must!
