Cover Crop for Indoor No-Till

Hey guys, so in nearly ready to set up my organic no till bed for my next cycle, just waiting on the bed itself.

I’m wondering what cover crops have the most shallow roots? I obviously don’t want them to compete too much, as I’ll have 4 plants in a 65 gallon.

I have alfalfa/clover growing in my outdoor pots right now, combined with a layer of mulch(mostly hay), and it seems to be working well, but I’d like to try something more fragrant and beneficial. Chamomile, peppermint, and lemon balm are three that have piqued my interest.

Let me know what you guys think, and if there aren’t others that would be better, as I’be read that peppermint and lemon balm can be invasive and compete with my cannabis plants.

Thanks!

I think there's a dwarf chamomile variety. Not sure how deep the roots go tho. I used build a soil's cover crop once. The buckwheat can be invasive if you don't kill it early. Still have buckwheat plants popping up almost a year later lol

I've been using crimson clover this grow...no complaints yet..My friend swears by companion planting with a strawberry plant
