The moisture content in Earthworm Castings varies quite a bit from batch to batch, and they dry out a lot, over time. It is best to get it moist prior to adding it to your base medium (soil). To do this - just add some water to the Castings and mix it up. I do this right in the bag. Add and mix until you have a nice rich loamy product. Then: Mix the castings into the base growing medium. Do not use more than 25-30% Worm Castings. Too much nitrogen can burn your plants. Thoroughly moisten the mixed medium, before planting your seeds atop it.
Earthworm Castings are a necessary ingredient - in our opinion - in the growing of Sunflower Greens. They offer more nitrogen to the growing plants which dramatically improves the quality of the crop - the Sunnys grow more rapidly, more evenly and shed their hulls more readily. Above all - they taste absolutely the best when grown with Castings.
The added nitrogen is also hugely important when growing Micro-Greens to the True Leaf stage.
Earthworm Castings are the excretions left behind by worms after they finish digesting the organic matter that makes up their diet. Now you know =:~).

Do not try to re-use a growing medium. Just compost it and start fresh with your next crop.
