Cannabis plants need as much light as possible this doesnt sound like something anyone should do?

Yeah, something about planting a cover crop after the cannabis has become established???

How about this?  Applying a thin layer of some kind of mulch around the plant to control moisture?

For outdoors. That would work. Right now the sun is beating down on any exposed ground and drying it up. If you have water close then it doesn't matter and actually gives to a chance to add water and nutes as often as you want to. However, if a watering source is difficult to use at a location the mulch would help. With my cannabis plants, they are big enough already to shade the ground beneath them and there's no need for ground cover. 

My pepper plants have plenty of exposed ground around them and they are drying out almost every day. They could use something to keep the moisture in the ground from evaporating.
