I ran 3 inch because you don't need all that space unless you want tree's. I had a few that got over 4 feet tall. No problems.
That's true, but considering how cheap a net pot is having this happen isn't a catastrophe. The biggest problem is that you might have some medium fall into your reservoir.

If you find out your cups are too small for your first grow (because they rupture) it's not a problem to just get bigger cups and cut bigger holes to fit them for the next grow.
killerm8r Reviewed by killerm8r on . small net pots This might be a dumb question, but I'm new to hydro. Right now I'm cloning into 2" net pots in the lid of a 3.5gl bubbler bucket. Would it be possible to complete the grow in those small pots or would the roots be too cramped? I can't find net pots around here, so I'll have to order again, otherwise I'd just get bigger pots. Keep in mind that I would do about 4 plants and only about 2ft vertical space above, so the plants wouldn't be too big anyway. Rating: 5
