Sorta its more that the nutriets the clover uses to grow comes from the air rather than the soil. Mow it often. I mow mine weekly. and what you mow will break down in the bed and release nutrients for the plants. Clovers are good for this.
Thanks.
I dont introduce any insects. Ive topdressed enough compost that I have plenty of insects. Never had aphids, thrips or mites. I also dont bring in outside plant life into my grow. When you first mix everything in let it warm, then cool, then water in your nematodes and Mycos source. Mites/nematodes will regulate their population based on food source. This is why mulching is important. If you mulch and use compost on your initial mix you will have plenty of mites. Water in just the nematodes/Rove Beetles to consume the fungus gnat larve and you will be good.
If you have compost you have a living soil. It may not be ramped all the way up, but that comes down too proper watering and proper mulching. I keep my clover growing always. Sometimes the cannabis will smother it out. I do try to prevent that if i can. But I never want just a pot of soil sitting. Something need to be growing in it. So mix your dirt, sow your clover. As soon as the clover is a inch long drop in your plants. 3 days later, mow your clover. I got some big ass grass shears. Take me 5 min to mow a whole bed.
Make sure if you do a 4xWhatever that you can get to 2 opposing sides always.
