If you're working with 100L pots, sure 😂
All kidding aside, it's a terrible idea.
Firstly, check with local and county laws if that's even allowed. Some countries have laws that clearly state, your plants are to be separate from others's.
Secondly, you're not going to be able to regulate each plant's specific needs by growing in one pot. For instance, one plant is fine with 0.5ml of CalMag, and another could need 1ml. The problem persists in regulating nutrients like Nitrogen, Potassium and Phosphor.
Don't even get me started on ph..
Just no. Even with auto flowers, keep the plants separate.
