Nice Sativa ya got thereI kept African Nightcrawlers and Red Wigglers separately, until I got lazy and just decided to keep the populations in the 45 gallon notill fabric pots I grow in. I also added some local earthworms from my backyard to the mix. If you want to keep them happy, add a thick mulch layer like wheat straw, because it breaks down quickly, and add your normal weekly topdressings under the mulch layer, and water your plant through the mulch. Another trick is to buy the wheat straw bale before the rain, and keep it outdoors. When the sun dries it out, there should be mushrooms sprouting out of it with lots of mycelium running through it. When you break it up, spores will be flying. Break that up and add it to the pots. The worms go flipping crazy. They crawl into the mulch. I have a constant supply of castings, and the thick mulch layer keeps my roots cool...in fact, here's my Ace Seeds Zamaldelica (zamal pheno) a few days after the garden hit 118f!
