I have 4 plants going in a small ~5 gallon container, and due to their recent growth explosion I need to get them moved into a larger container pronto.. They are all currently in 2 inch net pots. The only issue I can foresee with this is that they will need more support in the future than if I had used larger net pots. And fortunately that won't be an issue, are there any other problems with only using 2 inch net pots?
