I decided to follow up with my last post concerning the six day old seedling with the overgrown healthy root system.
Both of the following plants are summer squash and were planted at the same time. Keep in mind, I only did a comparison between summer squash plants in our garden, however worm tea results can be expected on all plants, even cut flowers in a vase will last longer!
The photo below is a plant that was planted as a seed with 5% worm castings added to the potting mix. Since then I have only planted in the garden and watered when needed.
Here pictured below is the summer squash I originally posted with the amazing root system at 6 days. It was planted as a seed with the same procedure as above. I have watered with a worm tea I made from worm castings twice in the past two weeks. This photo below was taken 14 days after my original photo showing the six day old seedling 
Next week I will be adding concentrated worm tea from here as well as worm tea bags in different sizes. If you are interested in ordering in advance, feel free to leave a comment below, filling in your email (will not be displayed online) and I will get back with you with sizes and prices on both.
As far as my experiment with seeds with varying amounts of worm castings, we had a wash out, literally. I left the plants on my covered porch; however driving rains ruined this test. I will be restarting this test shortly… so stay tuned.

What is LEC (liquid earthworm castings)?
It is an organic soil amendment made from 100% earthworm castings without additives.
It is a highly concentrated liquid easily applied through all irrigations/drip systems or foliar
spray and mixes readily with water, other fertilizers and herbicides.
4 It is 100% biogradeable, non-toxic, and will not harm the environment.
It is a biological load of trillions of micro-organisms (beneficial bacteria and fungi) per gram.
It has more than 12 of the most needed elements for the normal development of the plant.
It is a biochemical substance which includes humic and fulvic acids, as well as auxins,
gibberllins, and amino acids, among other growth enhancers.
What will LEC (liquid earthworm castings) do for you?
It has high chelating qualities which facilitates better uptake of nutrients.
This means less use of other fertilizers and more balance in the soil.
It improves the physical, chemical, and biological conditions of the soil.
It helps the plant handle stress from herbicide, prolonged overdoses of
agrochemicals, frosts, droughts, etc.
It facilitates the absorption of nutrients by increasing cellular permeability.
It stops retro-gradation of cations and releases tied up minerals into the soil.
